Troon - sea defence
Piecemeal coast protection measures adopted in the 1980s along the sea front
at Troon (see picture below) failed to halt erosion along the dune front. A
major investment was made in front of the Royal Troon Golf course in the early
1990s, following storms which caused the shoreline to retreat by 15m or so.
The Club laid 470m of gabion mattresses topped by a gabion
basket. This was only partly successful, and it has been suggested
a more extensive protective foredune should be built, which harnesses the positive
sediment budget in the area. The aim is to create a semi-natural appearance
to the coastal fringe using Leymus arenarius;
the main dune building species in the area (Wood
2001).

Guidance: A general conclusion can be reached as a result of
the actions taken at this. Clearly the geomorphological context needs
to be more clearly understood when undertaking remedial action to combat
erosion. It remains to be seen if these approaches will be any more successful
in the long term than those that have already been tried.
