FIG : - DESIGN OF ANTI SEA EROSION BUND AT SWAMINARAYAN TEMPLE, TITHAL - GUJRAT
PROBLEM
The Swaminarayan Mandir in Valsad-Gujarat is situated at a distance of around
200-250 m from the Seashore. The shore suffers extensive erosion due to strong
wave action and the formation of eddies contributed by the adjacent river and high
velocity winds. Seabed erosion had almost reached at the walkway of the temple
and posed a threat to the structure in the long run. The problem of erosion is so
tremendous that roughly 6-7 m of the shore are lost per year.
SOLUTION
The help of CWPRS was taken to restrict the erosion and have a full proof solution
in long run. After study of the problem CWPRS suggested the use of Polymer Rope
Gabion for construction of Anti Erosion Sea wall and using Woven Geotextile as a
filter media below the gabions.
C U R R E N T S TAT U S
After completion of the job, washed out land of about 30m x 330m was reclaimed
and is beautified by the temple authorities for pilgrimage purposes. The gabion
wall is performing very well and about 3m deep silting has taken place at the wall.
The sea wall after 4 years is absolutely in sound condition even after being
subjected to severe cyclonic winds and rainfall. No major maintenance cost has
been incurred during last 4 years.

FIG:- DESIGN OF SEAWALL AT THERONDA, DIST, RAIGAD
PROBLEM
The Theronda coast suffered bank erosion due to the tidal actions. The severity of
the problem was major as large portions of the land was getting affected due to
this.
SOLUTION
It was proposed to construct a parallel sea wall along the coast of the Theronda.
For the construction of the sea wall the use of polymer rope gabions was
proposed taking into view the effect of wave action and usefulness of gabions.
C U R R E N T S TAT U S
The project is still in construction phase and the completed portion of the wall has
reduced the erosion to a considerable proportion.

FIG:- TRAINING WORKS FOR VARSOLI CREEK, ALIBAG
PROBLEM
Varsoli, a village situated on the seacoast near Alibaug, Maharashtra, is a small
harbour that suffered a problem of bar formation in the entrance of the harbor.
This bar formation took place because of the tidal sand movements. As a result of
this the ships had a trouble in moving in and out of the harbor. The dredging of
this bar formation would have been a costly affair.
SOLUTION
After studying the problem, it was decided to construct two perpendicular
groyens to the harbour entrance. Two groyens one on each side of the entrance
having a length of 1km was proposed. For construction of these groyens use of
polymer rope gabions was proposed because of suitability to withstand cyclic
loading of waves.
C U R R E N T S TAT U S
Construction of About 500 m length of the walls on both sides is going on and is
giving good results. It will provide solution in the short term and long term to the
problem of bar formation near the entrance.

PROBLEM
The various stretches along the coastal line in Kanyakumari district were facing a
problem of severe bank erosion due to the tidal actions. This was causing a threat
to the nearby fishermen villages and some of the villagers need to shift their
structures away from the coast.
SOLUTION
It was proposed to construct parallel sea walls along the 28 stretches wherever
the severity of the problem was more. Use of polymer rope gabions was proposed
taking into view the effect of wave action and usefulness of gabions.
C U R R E N T S TAT U S
The project is completed and these walls have reduced the erosion to considerable
proportions. Its performance is much better than the old seawalls constructed there
by just dumping the stones without gabion and geotextiles.
