Coastline Manager is a package that allows the user to learn about the factors which need to be considered when deciding on how best to defend an area of coast from erosion and flooding. You take over as ‘Coastline Management Consultant’ whose job it is to plan the strategy for managing a section of vulnerable coast some 10 kilometres long. The coastline has varied geology, a wide range of human uses and a number of environmentally sensitive areas. You will need to balance the necessity to reduce erosion with the economic, environmental and aesthetic constraints of the area. Coastline Manager can be run on a number of levels each of which offers different challenges. You can research the background to coastal processes using the on-screen ‘Coastal Management Handbook’ or the two slide shows on Coastal Processes and Coastal Management. The aim of the game is to be as successful as possible in saving land and property over the ten years of your ‘contract’ whatever the level the simulation is being played at. Section 2 - Getting Started 2.1 System requirements IBM compatible PC with Windows 95, 98, NT, ME, 2000 or XP 10 megabytes of hard disk space free 16 megabytes of memory SVGA monitor (SVGA 800 * 600 resolution recommended for best effect) 2.2 Installing Coastline Manager Insert the Coastline Manager CD then Run the program setup.exe and follow the on-screen instructions. During installation the setup program will install all program and data files into a folder called Coasts unless you specify otherwise. Users have sometimes experienced difficulty at this point as it is necessary to confirm the destination directory in order to move on. The program says “Click this button to install Coastline Manager etc…” but which button to use is not that clear as the Exit Setup button seems to be the most obvious option. Hopefully the following diagram will clarify matters ….. This is the button to click! Hopefully all will then progress smoothly! Further information on installing Coastline Manager onto a network is available in Appendix 1 at the end of this user’s guide. WARNING: Normal installation automatically checks system files to see if any are out of date. On installation you may be presented with a message asking you to update your system files, if you wish to load the program then click ok and follow the on screen message. 1 User’s Guide Coastline Manager Section 3 – Running Coastline Manager 3.1 Getting Started To start Coastline Manager select ‘Coastline Manager’ from the Start menu. The following Screen will appear… Opens an Existing Project Creates a new blank project Opens the Coastal Processes Slide Show Opens the Coastal Management Slide Show Information Help This gives you direct access to the two slide shows if you wish to view them without entering the management program. However, to access the main program click on the button. To make it ‘user friendly’ Coastal Manager’ will ask for information about who is playing by asking you to register as a Coastal Consultant. All communication (in letters, application forms etc). are then personalised. 3.2 The thinking behind Coastal Manager To manage any area of coast there are a number of factors to be taken into account… • What processes are acting on this section of coast and how may they be a threat? • What is the physical geography of the coastline like? (geomorphology, sediment budgets, estuaries etc) • What is the human geography of the coast? (land use, sea use, roads, recreation) • Are there environmental factors to consider? (wildlife habitats, SSSI’s, RIGS etc.) • Are there aesthetic implications in modifying the coast? • What options are open to you as a Coastal Manager? • How much will it cost? Is it worth doing? Should we manage the coast at all? There are basically FOUR main options open to any Coastal Manager… 1. Do Nothing – let the sea take the land 2. Hold the Line – repair existing defences or put new ones in place to keep the coastline in its current position 3. Advance the Line – reclaim land from the sea protect / drain salt marshes. Create new farmland or land for building. 4. Retreat the Line – sometimes called managed retreat. Move vulnerable structures, do not allow any new building near the coast and work with coastal processes. The basis of most planning is embodied in the Benefit/Cost ratio. If the cost of carrying out a scheme (costs) are more expensive than the land and buildings being defended (benefits) then it would be silly to carry out the scheme. 2 The zoom buttons allow you to zoom in on selected areas of the map to see things in more detail. It is possible to enlarge the map areas up to 32* original size This is the main mapping screen. It allows ‘layers’ of data to be displayed in the form of lines, symbols and shadings. Individual elements (buildings, locations) are ‘hot’ and can be clicked to reveal further text or visual information. Opens modelling options module Accesses handbook and Slide Shows Displays or hides map Opens and Saves Projects Copy and Paste Functions Displays this screen for map displays 3D versions of selected map displays 3.3 The main display Coastal Manager 3 Runs simulation Displays balance sheets by year The ‘Display’ button activates currently selected options. Some activate automatically when selected. This ‘refreshes’ using current selection. Activates area interrogation functions Turns on defence building options panel Zoom out Transfers control to the panel which allows you to select which defences to build Allows any year covered so far to be reviewed. Turns on the overlay showing buildings and land lost to the sea Allows display of mapped ‘areas’ rather than linear features or locations Turns on grid lines and scale bar Turns on selected linear features and displays buildings and associated labels Turns on Help files for on-screen help Clears all settings and return you to the blank map (as shown here) Cycles through years to allow review of past events User’s Guide User’s Guide Coastline Manager Section 4 – Finding Out about the Coast 4.1 Using the Map The ability to display information on the map is the cornerstone to success in this project. The map is an interactive Geographical Information System (GIS) in many ways. Information can be displayed selectively about places, areas, zones and changes over time using the GIS. Areas of the map can be enlarged so things can be viewed in greater detail. This section will look at these mapping facilities and other data display functions to do with the coast to be managed. 4.2 The Map The map shows an area of coast some 7 kilometres long. The default display on start-up shows just the sea and the land. To add features to this map you need to use the ‘Display Settings’ panel to the right of the map. This allows attributes to be turned on and off, thus displaying any number of combinations depending upon what you wish to investigate. For ease of use these attributes have been divided into logical groups… • • • • • Linear features – Roads, contours, beaches etc. Specific locations – buildings, places OS Grid Lines Areas – geology, altitude, flood risk, land value Defence Structures It is easiest to think of each attribute as if it was a transparent piece of tracing paper, or overhead projector transparency. These can be laid on top of one another to give a simple, one layer map, or stacked so that several layers can be seen at once. This is the beauty of GIS maps. We will refer to each attribute as a ‘layer’. To select a layer for display simply click the ‘box’ to the left of the label (or the label itself). For most of the attributes the map will update automatically as soon as that layer is selected. 4.3 Linear Features Some examples… Main roads, Minor Roads and Woodland have been selected and are automatically added to the map Here Contours, Drainage (streams and rivers) and Beaches have been displayed. If you wish ALL linear features can be displayed at the same time. The simplest way to do this is to click on the All button Clear will turn all the layers in that ‘group’ off. For information on displaying ‘keys’ see page 4 Coastline Manager User’s Guide 4.4 Buildings To display the layer showing buildings select the ‘Buildings’ button. In the example here both buildings and place name labels are displayed. Note: ‘Hot Spots’ allows you to access detailed information about each building, such as address, distance from the sea, size, type, value for planning purposes. This is covered fully on pages 6 -7 in the section on Planning Your Project 4.5 Area maps So far linear features and those with specific locations have been mapped. There are attributes which cover the whole area. The maps for these are referred to as ‘Area maps’. Area maps cover layers such as… Geology Drift Altitude Strength Geology – displays the three main rock types underlying the area. More often than not these are buried beneath Glacial Drift from the last ice age. Drift – displays the glacial deposits which cover the solid geology and are exposed all along this section of coast. There are three main deposits, all of which vary in their resistance to erosion. Older till (25,000 years old), newer till (14,000 years old) and outwash sands and gravels Altitude – the higher the land the more there is for the sea to remove therefore the more slowly the coastline will retreat. Here it is shown as ‘layer shading’ between the contours. The same information can also be seen in a more simple form by just displaying the contours. Strength – this is a ‘calculated variable’. The harder the rocks, the more resistant the drift and the higher the land the stronger the area will be to resist attack by the sea. Quite a useful map for planning purposes. If maps do not display on selection simply click the button at the foot of the display panel. 4.6 Cellular Maps For modelling purposes it is convenient to divide the map up into ‘cells’. This aids calculation and allows each cell to be given values for planning and simulation. It is possible to display some of these ‘cellular values. Flood Risk Land Classes Land Classes The map on the left shows areas which have been calculated to be susceptible to flooding (low lying and coastal). The map on the right displays the quality (therefore value) of farmland. 5 User’s Guide Coastline Manager 4.7 Grid Lines The options allow you to display OS style grid lines and a scale bar. These automatically re-scale if you change the scale of the map (see next section). Grid References are referred to in the planning and positioning of features, and the location of ‘erosion events’ during the running of the simulation. The current grid reference of the cursor is displayed in the panel at the base of the Display Options if the Grid is turned on. 4.8 Scale Bar and Compass The scale bar and compass rose appear to the south of the map and are set to the currently selected map scale. De-selecting in the display options panel can turn them off. (see above) They can be moved to another place on the map by dragging and dropping the bar or compass. 4.9 Defences and Labels If you have defences in place then selecting these options allows you to display or hide these structures and their associated labels. 4.10 Information (Info.) This option displays sensitive locations which need to be considered in your planning. They appear as ‘icons’ on the map and fall into five categories… Geological Ornithological Environmental Aesthetic Cultural/Historic 4.11 ‘Hot’ Locations As well as being able to see where places are the power of GIS is that it allows you to access layers of information which cannot normally be ‘mapped’. The same is true with this map. Specific locations have other layers of data, both text and visual, associated with them. For the purposes of this application these are referred to as ‘hot spots’. There are three main types of ‘hot spots’… 1. Information Hot Spots To reveal these extra layers simply move your mouse over the Information Icon (see above). It will then display a circle around it to show that it is active and summary information. Now click on the hot spot to reveal the full information. In some cases extra information is provided in the form of photographs. If a photo is attached to the ‘hot spot’ then this appears at the top of the Information Window. To copy either the text or the photo simply place the mouse over the item to be copied. A ‘copy button’ will appear – click it to copy. Copy displayed text 6 Coastline Manager User’s Guide 2. Defence Hot Spots The defence labels are ‘hot’ and interactive when turned on. Clicking on the numbered circle accesses information about the associated defence or structure. 3. Building Hot Spots To access this facility the buildings must be turned on and the ‘hot spots’ must be activated on the Display Panel ( see page 2) As you move your cursor over the houses a red circle appears to indicate that they are ‘hot’. If you then click on the house an information panel appears telling you about the selected building. 7 User’s Guide Coastline Manager 4.12 Displaying Keys When displaying maps a number of keys are available. These will appear automatically when new layers are displayed. They appear in the bottom right hand corner of the map screen by default, but they are movable, and can be dragged to other places on the map panel if required. You can turn the key display off easily by clicking on the ‘Hide’ button on the key display. You can also control whether a key appears or not by using the ‘menu bar’ at the top of the window. In this example the Map Symbols, Altitude and Defences are all displayed. To turn any of them off simply deselect it by clicking on it. It will still be shown on the menu (meaning that it is available for display) but it will not have a tick alongside it. Keys which are currently unavailable, as that layer is not displayed, are shown ‘greyed-out’. You can display ALL active keys on or off by selecting the “All active keys On” (or Off) option. Where multiple keys are displayed Coastal Manager ‘stacks’ them. In some cases keys have been deliberately designed to show information about more than one layer, for example, Geology and Drift are combined onto one key if both layers are requested. If a key fails to display properly simply go to the menu bar and turn it on from there. 4.13 Extra Information from keys At the bottom of some keys is an ‘information icon.” On clicking the icon an Information Panel appears which elaborates on factors associated with the topic covered by the active layer. Another level of information can be accessed from this panel also. The Coastal management handbook can be automatically accessed by clicking the Open handbook button (see page 12 for information about using the handbook). 8 Coastline Manager User’s Guide 4.14 Changing the Scale of the map It is possible to view parts of the map in more detail by ‘zooming in’. To do this you click on the ‘zoom’ button on the Display Panel. Zoom In Zoom Out Full Map Zoom in enlarges the scale of the map Zoom Out reduces the scale Full Map shows the whole map in the map panel a. Zooming In When the Zoom In button is selected an ‘enlargement frame’ appears in the top left corner of the currently displayed map. To zoom in on an area of the map drag this frame over the area you wish to enlarge and ‘drop’ it into place. The map will then display your selected area at the new scale. Dragged and dropped here… Position of enlargement frame …to give this map It is possible to enlarge sections of the map up to a scale of 32 times the original size. To do this just repeat the drag and drop routine of the enlargement frame. *1 *4 b. To Zoom Out click the ‘Reduce Enlargement’ 9 *16 button User’s Guide Coastline Manager 4.15 The ‘Locator’ map It is always useful to know just whereabouts on the map you are if you are viewing an enlarged area. The ‘Locator’ map resides in the North West (top left) corner of the map. When the map is first displayed it is ‘full size’ and there is no real need for a locational map to be visible. However, as you zoom in it is hard to keep track of just where you are in the bigger picture. To turn on the Locator Map just click on the map icon. This will now display the area you are viewing as a square on the Locator Map. To turn off the Locator Map click the a. Moving around the Map If the map is enlarged then all of it is not visible therefore you may want to view a part of the map which is just off the screen or simply ‘scan’ along a section of coast. This can be done using the ‘arrow buttons’ which are situated … in the corners and at the mid point of each side of the map. If the Locator Map (see above) is active then you can ‘drag’ the square showing the currently selected enlargement area to a new location. The map will then re-draw to show the newly selected area. Note: The map re-draws all enabled layers so, if you are displaying a ‘complex’ layer which takes a while to refresh (e.g. cellular strength) then it may be best to turn this off, navigate to the new location, then turn it back on again. Saying this, if the map is enlarged then only the displayed cells are re-drawn and it can be very quick. Try it and then make a decision. b. Re-centring the Map There is a facility to re-centre the map. This can be done using the Re-Centre button. This button only appears if you have the map enlarged. On clicking this button your cursor changes from an arrow to ‘cross-hairs’ + When you next click on the map it will be centred over the location you have clicked. 4.16 - Overlay lost coast When modelling or looking back on previous years you can choose to either see features which have been lost to the sea (overlay) or not. To turn the overlay on use the ‘Overlay Map’ button to the right of the Re-Centre button (see above also) Original Coast Overlay Off When the overlay is turned ON the button displays an ‘overlaid coast’ and the ‘prompt text’ (which appears when the mouse is placed over the button for a second or so) confirms this. Similarly, when turned OFF the image on the button and the ‘prompt text’ indicates this. 10 Overlay On Overlay ON Overlay OFF Coastline Manager User’s Guide 4.17 3D Views It is possible at any time during the project to see what the coast looks like from a 3D perspective. To see the 3D version of the map click on 3D Map on the menu bar at the top of the main map window. This will display the screen below. The 3D map detects the current settings for the main map and applies those. They can be changed in the same way as on the main map window (see pages 2 – 5). It is possible to turn ‘blocks’ of options on or off using the does what it says, turns off all options in that block. button. If your selection does not display on demand click the button. Controlling the appearance of the 3D map The perspective of the map can be controlled to some extent. This is done using the slider bars below the map. Widens or narrows the map while retaining all other settings Stretches the map vertically from its existing baseline. Raises or lowers the point from which the map is viewed. Resets all three options to their default (central) settings. Allows you to view through the years you have planned so far. You cannot view years which have not yet ‘run’. (see running years) Displays the original coastline and all features (assuming they are turned on) so you can see what has been lost. Close the 3D map… Copy the map… Print the map. 11 User’s Guide Coastline Manager Section 5 – The Coastal Management Handbook 5.1 – The Management Handbook The Coastal Management Handbook is a source of a wide range of information which will help you to make decisions about managing the coast. It is divided up into four main sections covering… 1. Coastal Processes 2. A section on features created by erosion and deposition 3. A unit on a range of management strategies 4. Tables of information on land/property values and costs of defences To access the Handbook select from the menu bar On doing this the Coastal Management Handbook will appear. To open the Handbook simply click on it as instructed at the foot of the front cover. This accesses the ‘Contents Page’. It is possible to either ‘read’ the book, starting at the introduction and working your way through, or to ‘turn’ straight to selected pages from the Contents Page. Whichever you choose, the page can be viewed by clicking on the green heading at the left hand side of the page. Clicking on ‘Waves’ will give… To return to the Contents click the Button. To turn over to display pages 4 and 5 click on the To turn back use the button. Copying Information from the Handbook It is perfectly possible to copy either the images (maps, photos etc.) or text from any of the pages in the Handbook To do this simply RIGHT CLICK on the element you wish to copy and it will be placed on the clipboard. To Close the Handbook click on 12 Coastline Manager User’s Guide Section 6 - Opening a slide show for viewing 6.1 Running a Slide Show There are two slide shows which accompany the Coastal Management application. They cover Coastal Processes and Features and Coastal Management. To open either of these select Slide Shows from the menu bar then choose which of the two shows you would like to run. On opening a show the main slide show viewing screen will be displayed. A range of functions can be accessed from this screen. These are outlined below and will be explained in detail on the following pages. Main slide display screen Slide title panel Loads a new slide show Move to new slide Help Copy current text Copy current photo Save all or part of commentary Print current photo View all photos in the set to select a slide Print all or part of commentary Displays enlarged image Open the main glossary screen Main commentary display panel Highlighted text denotes keyword in the glossary – double click to see definition Alternative route to glossary – select word then click this button 6.2 Moving through the slide sequence To move from one slide to another simply click the ‘slider bar’. The associated commentary will be displayed beneath the slide. 6.3 Slide-based functions Copy: This button will copy the currently displayed image to the clipboard for transfer into another application, for example a ‘Word’ based report. Print: This button will send the currently displayed image to the printer. A standard ‘Windows’ printer dialog allows formatting etc. Browse: This useful function displays ALL the slides on one screen. Individual slides can then be accessed in whatever order they are needed and viewed at a larger scale, copied, saved or printed. Full Screen: Displays a full-screen enlargement of the current image 13 User’s Guide Coastline Manager 6.4 Using the Slide Browser Clicking the Slide Browser button accesses the Browser Window. This displays all the slides which are associated with the current slide show. Each slide is numbered in the display order. As the mouse is moved over each image its title is displayed above the images. To view any one of these slides simply click on the slide you wish to see. The selection is displayed as a ‘full size’ image. Copy Save As Enlarge To return to the Browser click on the picture. To return to the Slide Show click Copy and Save As functions do as they suggest. 6.5 Commentary Functions When slides are displayed using the Slide Viewer (see p.3) the commentary for that slide is displayed in the panel below the image. In the same way as it is possible to Copy, Save or Print images the same can be done for the text. If Copy is selected it is possible to copy either just the commentary associated with the currently displayed slide or the whole commentary. You will be prompted to select one of these options (see opposite) Selecting the Print button offers the same options. Save As allows you so save the whole commentary as a Rich Text File under a different filename or to a different location. Because the file already exists it is easy to access the original, but it may be that you wish to make changes to enable it to be used for another purpose, so a copy is quite useful. Once again, you will be prompted to this effect. 6.6 Accessing the Glossary - from within the commentary You will notice that some words in the commentary are shown in Bold and Red. These words are highlighted because definitions or explanatory notes about them are included in a Glossary. There are two ways to access these definitions. 1. By double-clicking on the word or 2. Selecting the word or words with the mouse or keys and clicking on the 14 button Coastline Manager User’s Guide Two options are offered because when you double click on a word only the one word is selected and it is this word which will be searched for in the glossary database. For example, in the sample show on Processes, “Differential Erosion” is covered. Double clicking on this would highlight ‘Differential’ (if you clicked on the first part) or ‘Erosion’ if you clicked on the second. So, to access the whole term you need to select ‘Differential Erosion’ either with the mouse or shift and arrow keys, then click on the button. This allows the use of groups of words rather than just single words in the glossary. Whichever option you choose displays the definition for the word(s) you have selected. This is the definition panel displayed when the word ‘Erosion’ is double-clicked in the commentary for slide 3 in the Coastal Processes show. ‘Double’ words, such as this can also be accessed in the same way. If this doesn’t work then try using the ‘select and click button’ technique. If a term cannot be found in the Glossary, or you double click on a word which is not highlighted in red then an error message will be presented. This can also occur if you select leading or trailing spaces when dragging the mouse or using the shift/arrow keys. When the Definitions Panel appears then words which are in the Glossary appear in red here too. Simply double-click on these to access their definitions. 6.7 Accessing the Glossary - directly It is also possible to access the Glossary and associated definitions directly. Simply click on the (View Glossary) button Æ and a list of all defined terms will be displayed. To view a definition just click on the word or term you wish to see. On selecting the word you wish to view, the ‘Definition Panel’ will appear below the Glossary List. The button on each panel will do just that, however, there are slight differences… • • Close on the Glossary List panel closes both the glossary and Definition panel Close on the Definition panel closes just that panel. 6.8 Getting Help To access the Help files which accompany this application click on the 6.9 Leaving the current Slide Show To leave the current show and load a new show click on To leave the Slide Show completely select 15 button User’s Guide Coastline Manager Section 7 – Modelling and Risk Assessment 7.1 Setting Up and Running a Model Before you spend any money on defences you need to know just how vulnerable your coast is. It is possible to model (simulate) the effects of erosion on the coast at any time in the running of Coastline Manager. It is best done BEFORE any commitment is made to defences, just to get an impression of where your priorities might lie. To activate the simulation, and model the retreat of the coast, select Model then Set Up Simulation from the menu bar This will open the Simulation Settings Panel (see below) You can determine the starting year for the simulation Set the year in which your simulation run finishes Allows you to pre-set a pause during the simulation sequence If set to ‘On’ a line is left marking the position of the earlier coast at intervals you determine If set to ‘On’ then all roads and buildings are left displayed even if now in the sea. By setting the Sea Level Rise you can model best-case or worst-case scenarios You can determine the speed at which the simulation runs Resets to the settings you see above Starts the run Examples of the results of a simulation are shown below. Cancels the option It is possible to run the model when an area of the map has been enlarged. However, it is better to run it at ‘full size’ then zoom in to the area you wish to look at in detail. Before Modelling After Modelling (Overlay ON) 16 Coastline Manager User’s Guide After having run the simulation you can manually view selected year’s situations. Select View Simulation Year from the menu bar then select the year you wish to view from the panel. Click OK to display the new coast. Current ‘transparency’ settings apply. Cancel will return control to the main program in the currently active year. When the Model has run this panel appears. Selecting Return to Project will return control to the main program in the currently active year. Reset makes all setting as default (see previous page) Pause pauses the simulation while running (Continue re-starts) Run re-starts the paused simulation 7.2 Assessing Losses ‘Assess Losses’ automatically calculates the land and properties which would be lost given the simulation setting selected. These calculations are based on the map information displayed. On selecting Assess Losses this window appears. The currently selected map area is displayed together with a statement of the average width of coastline lost in the time scale of the simulation. In this case it is 404 metres over 50 years. Further detailed reports can be accessed by clicking on the ‘Tabs’ above the map. These are shown below. Summary Houses Other Properties Land Roads Cost-Benefit Utilising these screens accesses a range of other modelling facilities, particularly the ability to carry out a detailed cost-benefit analysis on the currently selected coastline. 17 User’s Guide Coastline Manager 7.3 Risk Assessment The simulation described on the previous page tends to work best to get an overview of the whole area. It is often better to focus in on one specific location and find out its strengths and weaknesses. This can be done using the “Area Investigation”. To set this up select Planning then Area Investigation from the main menu bar. On selecting this the following options present themselves… Include all within selected area assesses all losses within the selection frame regardless of how far away from the sea it is. It may well include land which would not normally be lost. However, it is easy to apply and a useful option. Set Selection Zone allows you to state the ‘fringe’ of coast (say, 100 metres) which you wish to include in your assessment of losses. A dropdown panel and scroll-bar allows this distance to be set. Use 50 Year loss line uses the calculated average distance of the coastline in 50 years time (as determined by your simulation parameters) as the landward boundary of loss. Click Activate to apply your chosen settings. Once the settings are applied simply click the left mouse button, hold down the button and drag the selection rectangle to delimit the chosen study area. When the mouse button is released the “Assessed Losses” window appears (see previous page) but this time it only displays and assesses losses within the selected area. This is really useful for small area assessments when money is at a premium. This style of assessment can be carried out on quite small areas if the map is enlarged first ( see ‘Zooming In’ on page 9) Click here Drag to here If a Selection Zone is specified or the 50 Year loss line (see above) the resulting map display shows the inner fringe of the selected area as a purple line on the map. This time the figures displayed in the tabbed tables include only those losses of land and property between the present coast and the purple loss-line. Inner limit of assessment 7.4 Cost Benefit Assessments This is the cornerstone of coastal management. It is crucial to know if the cost of proposed defences exceeds the value of losses. If it costs you more to build the defences than the land and buildings are worth then it would be silly to proceed. This facility allows you to model a range of possible scenarios to aid decision-making before the money is committed. 18 Coastline Manager User’s Guide Having selected our area of study and selected Cost/Benefit from the tabbed menus we can see that the land and property within 100 metres of the coast (our own setting) is worth £1,796,900. Obviously, if we did nothing then this is what we would lose. Clicking the bottom of the table button confirms this at the To see what would happen under a range of circumstances simply select one, or more of the defence options and click the button. The example opposite shows the financial implications of a sea wall used to protect the coast which is in a similar selection area. It would cost £2,021,250 to defend land and property worth only £1,798,900. Costs outweigh the benefits and it gives a Benefit/Cost Ratio of less than one (the threshold/breakeven point) Having determined that the sea wall is too expensive maybe we could try something else? This time we spending less, as groynes are cheaper. Now the whole thing becomes far more cost effective, and the Benefit/Cost Ratio swings in our favour at 1.46:1 On selected high-value areas it is perfectly possible to use combined defences such as groynes and beach-feeding. There are certain combinations that are not allowed such as gabions and sea walls(which basically do the same job) You cannot sensibly use sea walls, rock armour, revetments or breakwaters with one another so these combinations will be de-selected. 7.5 Non Monetary Considerations Not everything has a monetary value. There are things of aesthetic, cultural or environmental value. These are shown on the map as icons (see page 6) These will be detected in your ‘sweep’ of the area. Here the ancient village of Walton has been included in our potential loss area. Clicking on the cell which says “Click here for details” displays further information about this resource. Clicking on the button generates an illustrated report in Rich Text Format (.rtf) which can be saved, copied to a project write-up or printed. 19 User’s Guide Coastline Manager Section 8 - Building Defences 8.1 Building Defences Having interrogated the map and modelled possible outcomes the time will come when you wish to put some defences in place. Step 1 - As defences are costly this is best done accurately. It is recommended that you enlarge the section of coast you wish to work on to at least 4 times normal size (see page 9). This ensures more accurate placements and no wastage. Step 2 – Change from the Display Setting panel (see page 3) to the Construction Projects panel by clicking on the button at the foot of the Display Settings panel. This will display a panel which offers a range of Structures from which to choose. There are two main types… Defences and Roads. It is sometimes more cost-effective to move a road back away from the coast (retreat the line) than it is to build costly hard engineering structures to ‘hold the line’. Step 3 - The cost of both building and maintaining the defence is displayed alongside the picture of the defences or roads. Clicking on the images provides extra information taken from the handbook, but displayed in a separate window. The information from both the text and the images in these panels can be copied easily. As the mouse is placed over the image a ‘copy icon’ will appear in the image or text panel. Simply click on this. Step 4 – Select the defence you wish to use by clicking the button to the left of the image and its heading. A panel will display showing you how much money you have left to spend this year. (see left) On closing this the following window (see right) will appear on the map. It states … a. the defence you have selected b. how much you have built in this section c. costs of building this section d. how much money you have left to spend Step 5 - Place your mouse on the section of coast where you wish to START your building. Hold down the left mouse key and run the mouse down the coast to build your defence. The defence will be drawn in as a coloured line. As you build the Cost and Balance panels update to show the current status of your finances. You can cancel the build if you change your mind by clicking on the 20 button. Coastline Manager User’s Guide Step 6 – If you have not exceeded your budget (see below) Confirm your build by clicking on the button. When you do this the defences will be put in place and will show as either a coloured line (if working in normal size mode, or as a set of coloured symbols along the coast if using an enlargement of *4 or more. A key panel showing these colours and symbols will be automatically displayed. If you have the ‘Defence Labels’ turned on then a label indicating the project number will be displayed alongside the structure. You can always check the status of existing on newly built defences by clicking on the numbered circle. (see page 7) 8.2 Incompatible Combinations It is possible to have more than one defence along a section of coast. However, you cannot put two defences which basically do the same job along the same bit of coastline, so Coastal Manager blocks these options. A message box will appear letting you know what you have in place already and that the proposed defences are incompatible. Incompatible combinations are shown as ‘X’ Armour Blocks Armour Blocks Gabions Revetments Groynes X X 9 9 9 Sea Wall X 9 X X X X 9 9 9 X 9 X X 9 Gabions X Revetments X X Groynes 9 9 9 Offshore Breakwater 9 9 9 9 Sea Wall 9 9 X X 9 X 9 9 X X Beach Feeding X Offshore Breakwater Beach Feeding 9 9 8.3 Building Roads Sometimes it is more cost-effective to MOVE something that is threatened by flooding or erosion than it is to defend it. This is certainly often the case with roads. Replacement roads can be built in the same way as defences. At the bottom of the defences window are the two option buttons which allow roads to be selected. There are two styles of road which can be built… main roads and minor roads. Main roads are more expensive, at around £1000 per linear metre. Minor roads cost less, around £700 per linear metre. To build a road simply select the road style by clicking on the option button. To make best use of your money accurate road building is essential. This is best done when the map is enlarged. If the map is smaller than 4 times normal size you will be prompted to consider enlarging the area. If the map is at ‘normal’ full screen size, with no enlargement, then all you need to do is to close the Information Box by clicking on YES then click on the map where you would like to zoom in. The new map, enlarged to four times normal size, will be centred on the point where you clicked. 21 User’s Guide Coastline Manager Note: You CANNOT build roads unless you are zoomed in to at least four times enlargement. This is for two reasons… firstly, it is far more accurate and saved money, secondly, there is no way that a road longer than even half a screen a four times enlargement could be built with the money available. If you wish to zoom in manually then that is not a problem, simply close the Information Box by selecting NO and use the Zoom buttons to enlarge the map and select the area you wish to work on. Once the map is enlarged then ‘nodes’ will appear on all existing roads (see left). These mark the points at which each segment of road starts or finishes. You use these nodes as start and finish points for your new roads. Roads MUST start and finish at an existing node. To Start a New Road 1. Make sure the correct road type is selected in the ‘Defences and Roads’ panel. 2. Move your mouse over the road nodes. They will change colour to green when ‘active’ 3. Click to select your starting node, it will turn blue On doing this the ‘Construction Costs’ window will appear. This updates as you continue to build. 4. Move the mouse to the end point of your first new segment (you can have as many new segments as your finances will allow). A dashed line will show the position of your proposed segment. 5. Click on the map to create a new node. This will appear in blue. 6. Repeat stages 4 and 5 until your road nears completion. 7. To finish the road click on an existing node on one of the original roads then select ‘Confirm Build’ on the construction panel. 8. The road will now be drawn onto your map Once you have built the road it will be identified in the same way as the defences, with a numbered circle representing the ‘Road Project’ number. As with defence projects, clicking on this circle will allow you to review information about that project. 22 Coastline Manager User’s Guide 8.4 Overspending! You have a limited budget to work to each year. This is shown in the ‘Building Window’ (see p. 20) and is updated as you create your defence. If you overspend then your attention is drawn to this in two ways… 1) If you overspend by less than £100,000 then you are warned in the ‘Financial Problems Ahead’ Window. There are three options open to you… a) Build as planned and carry your overdraft on to the next year b) Apply for an extra grant from DEFRA (see next page) c) Cancel this project and try something different. 2) If you overspend by more than £100,000 then the project will be cancelled and you can reconsider your options. 8.5 Applying for a Grant If you decide to apply for a grant just click on the button. Coastline Manager anticipates how much you may need to cover this project and where you intend to build the defences. You will then be offered an ‘on-line’ application form already formatted for you. The sum of money needed is rounded up (in this case from the £44,329 shown above to £50,000). It is also noted whether you have already applied for a grant this year. If you wish to proceed with the application as it stands click on submit. You can change the options before you submit the form by clicking on the ‘drop-down’ panel arrows. Your application will be checked and you are informed ‘by post’ of the outcome. Clicking the letter opens it. The letter either confirms the allocation of a grant or its refusal and why. Any money given in the form of an extra grant does not have to be paid back, unlike the overdraft outlined above. 23 User’s Guide Coastline Manager Section 9 – Running the Simulation 9.1 Running a Year Once all modelling, interrogating, cost-benefit analysis and building is done it is time to run the simulation and see how well you have done. To run the year click on in the main menu bar at the top of the screen. Coastline Manager will then … • select a random weather scenario for the year which determines the rates of erosion along the coast • apply this to the coast and remove vulnerable undefended sections according to a pre-determined ‘strength’ ratio (This can be viewed as a map – see section1) • assess the effectiveness of defences you have put in place If features other than farmland are threatened during this run then a warning is issued. This informs you what is happening and where. You are offered the option of putting Emergency Repairs in place. These are charged to your account at £1000 per metre If you opt to do this then your choice is confirmed. The simulation then continues to cycle through the months of the year. At the end of the year a “Situation Report” summarises the outcome of the year.

A summary of the Cost/Benefit situation for the current year is also available (see below) 9.3 Graphs of success rates The button accesses a set of four graphs which display the following data sets… The content of the graph can be selected by clicking on the ‘Options’ button at the bottom of the graph window. ‘Copy’ and ‘Print’ do what they say. 25 User’s Guide Coastline Manager 9.4 Looking Back at Previous Years It is possible to review any of the displays relating to previous years which have been run. To do this click on Review in the menu bar then select the review option you require. • • • Review Year allows you to select any year Review Last Year does just that Saved Land and Buildings takes you to the Details displays shown on the previous page 9.5 The Final Year! When you run Year 10, the final year in your contract, the usual summary of the year’s events will be displayed (see Situation Report on page 23) When that window is closed the Final Summary Window appears This accesses summary tables of all key areas of your project. Examples of these displays are shown below. Overview Projects Success Finance Managing a coastline is a delicate balancing act which involves understanding natural processes, assessment of risk, an awareness of aesthetics, a sensitivity to the natural world and being able to make balanced judgements when it comes to decision making. Cost/Benefit Analysis is at the heart of this process but there is more to costs than money. Coastline Manager allows you to model and test outcomes, make these decisions then review the consequences of your actions. Next time you visit the coast maybe you will view it with fresh eyes. 26 Coastline Manager User’s Guide Section 10 – Saving and Opening Projects 10.1 Saving a Project Active projects can be saved at any time during the simulation. All current settings, values, defence projects and finance information is saved. Other data is re-calculated on loading to re-construct the coast exactly as you left it. To save an active project select File then Save Project from the menu bar This will present the standard “Windows” Save As screen. Coastline Projects are saved as Shoreline Management Projects with a file extension of .smp It is best not to change this as Coastline Manager automatically searches for these files by their ‘extension’. If you do save them without the .smp don’t panic, simply change the ‘type’ to “*.* (All Files)” when loading (see next section). 10.2 Loading a Project If you are loading a project from a ‘cold start’ – the Title Page, then click on Load an Existing Project button (see below) This will re-instate the map to its default values then give you this window… Select the file you wish to load. If you have saved them with the default extension of .smp then they should be displayed automatically. If they do not appear check that you are in the correct folder. If that does not work then change the ‘Files of Type’ option to…*.* (All Files) and see if they appear then. 27 User’s Guide Coastline Manager Section 11 – Getting Help Help can be obtained in one of three ways… 1. Selecting Help from the menu bar at the top of the main mapping screen 2. Clicking on the button if it appears anywhere on a window 3. Pressing the F1 key This accesses what is known as ‘context sensitive help’ and takes you straight to what are considered to be the most appropriate page(s) in the help files based on the ‘windows’ which are currently active. It is still possible to navigate around Help using the ‘Contents’ menu or to Search using Help search facilities. See Windows Help for further details of these facilities. 28 Coastline Manager User’s Guide Appendix 1 Installing Geopacks Software on a Network Geopacks Software is written in Visual Basic and in order for it to run it is necessary to install files into specific locations on any computer that is running the software. • • There are the program (or application) files, which are installed into the folder chosen to hold the programs themselves. This is selected by the user when setting up the install sequence and prompts to this effect will be displayed. Other files (the ‘system’ files which actually run the code) are installed automatically into the Windows System folder on the host machine. On a standalone machine the files are installed into their correct locations automatically and after installing the programs should run with no extra ‘tweaking’ However, installing on to a network is different to installing onto a standalone PC. Due to the way in which Windows locates the required files it is necessary to undertake a few extra steps during the installation process. If you have bought a network version of the software and do not have a network, but wish to install it on to more than one computer, please contact Geopacks. To install on a network… 1) 2) 3) Install the software onto the server in the usual way. If you use install software like Install Wizard or Winstall you will need to replicate the files installed in the \Windows\System folder into the equivalent folder of the client machines. If you need to manually install the \Windows\System folder files, you need to copy the files listed in Table 1 on the next page from your \Windows\System folder on the server to the windows system directory on the client machine. Table 1 on the next page identifies the ‘System’ files for each application in the current Geopacks Suite of software which need to reside in the \Windows\System folder of client machines which will run the software. 4) 5) You will need to map a network drive from the client machine to the server. Make sure that applications are installed in a folder on the mapped drive but that the application folder is NOT the root folder of the mapped drive. Create a shortcut from the client machine to the ‘start-up’ program for each application in the mapped drive and folder on the server where you installed the application software. The start-up programs for the Geopacks Software are as follows… Slope Analysis Channel Analysis Sediment Analysis Roundness Analysis Bedload Analysis Orientation Analysis Sediment Analysis Full Fieldwork Suite Channel Analysis Slope Analysis Mastering Mapwork Down on the Farm (Main Program) Down on the Farm (File Manager) Slide Show Maker Slide Show Viewer Coastal Manager The software should now work from a client machine. 29 Slopes.exe Chan32.exe Cailleux.exe Bedload.exe Orient.exe Fines.exe channel.exe slopes.exe startup.exe farm32.exe FileEdit.exe Make32.exe View32.exe Coasts.exe User’s Guide Coastline Manager Table 1 – Files to reside in \Windows\System folder (or Microsoft Shared\DAO folder in the case of two files used by “Down on the Farm – shown at bottom of the list) COASTAL MANAGER SLIDE SHOW DOWN ON THE FARM MASTERING MAPWORK FIELDWORK FULL SET SEDIMENT ANALYSIS CHANNEL AALYSIS SLOPE ANALYSIS INSTALLED FILES ‘RUN-TIME’ FILES COMMON TO ALL APPLICATIONS Msvcrt40.dll 3 3 3 3 3 3 Msvbvm60.dll 3 3 3 3 3 3 Stdole2.tlb 3 3 3 3 3 3 Oleaut32.dll 3 3 3 3 3 3 Olepro32.dll 3 3 3 3 3 3 Comcat.dll 3 3 3 3 3 3 Asyncfilt.dll 3 3 3 3 3 3 Ctl3d32.dll 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 EXTENSION FILES USED BY INDIVIDUAL APPLICATIONS COMCTL32.OCX 3 COMDLG32.OCX 3 3 3 3 3 3 3 EXPSRV.DLL 3 GAUGE32.OCX 3 3 3 3 3 3 GRAPH32.OCX 3 3 3 3 3 3 3 GRID32.OCX 3 3 3 3 3 GSW32.EXE 3 3 3 3 3 3 3 GSWDLL32.DLL 3 3 3 3 3 3 3 MFC40.DLL 3 3 3 3 3 3 3 MSCOMCTL.OCX MSFLXGRD.OCX 3 3 3 3 3 MSJET35.DLL 3 MSJINT35.DLL 3 MSJTER35.DLL 3 MSMASK32.OCX 3 3 3 3 3 MSRD2X35.DLL 3 MSREPL35.DLL 3 MSSTDFMT.DLL 3 PICCLP32.OCX 3 3 3 3 3 3 3 RICHED32.DLL 3 RICHTX32.OCX 3 SPIN32.OCX 3 3 3 3 3 TABCTL32.OCX 3 3 THREED32.OCX 3 3 3 3 3 3 3 VB5DB.DLL 3 VBAJET32.DLL 3 FILES TO GO INTO ‘PROGRAM FILES \ MICROSOFT SHARED \ DAO’ FOLDER DAO350.DLL 3 DAO2535.TLB 3 This information can also be found on the CD in a Word file called “Network Installation.doc” 30 3 3 3 3 3 3 3 Coastline Manager User’s Guide Batch copying of system files There are two supplementary folders on the CD which are not used during the setup process. The files in these folders are extra copies of the System Files which are installed into the Windows System folder or, in two cases, the Program Files/Common Files/Microsoft Shared/DAO. As covered above, they need to reside on the hard drive of each workstation that will be used to run these Geopacks applications. They are installed automatically onto the hard drive of the computer which is used for installing the applications. However, several network managers have suggested that it would be easier to have them all in one folder on the CD as well. This enables ‘batch’ copying onto the C:\ drive of workstations which will run the Geopacks applications. So, there are two folders on this CD which contain these files. They can be found in the ‘Files’ folder. The SysFiles folder contains all files which reside in the System Folder. The ShareDOA folder holds the two files which go into the Program Files/Common Files/Microsoft Shared/DAO folder. WARNING: Normal installation automatically checks to see if a file you are trying to install is already present or not. If the file to be installed is more up to date than the existing version it will update it with the later version. If it is older it will either leave it or gives you a warning and recommends that you retain the existing, newer, version. BE CAREFUL if block copying not to overwrite newer versions of these system files as it may cause problems with other software on the machine. Geopacks software deliberately uses slightly older versions of some system files to ensure compatibility with as wide a range of Windows versions as possible. This does not affect the functionality of the software. 31
