Sea has eroded part of path running in front of seawall at Seawick
By the time the sea can reach these rocks, after it has eroded the rest of the path, the rocks will simply fall into the sea.
The sad thing is the solution has been known for hundreds of years, build groynes.
Even worse the solution has been successfully used a few hundred yards to the north at Seawick.
So the recipe is
- Don’t pile rocks agains the sea wall
- Use rocks to build groynes perpendicular to the sea wall
- Ensure the groynes are higher than the sea at high tide
- Don’t build the groynes too far apart
At Seawick groynes have been built correctly
What’s been done wrong?
- Instead of building a groyne perpendicular to the sea wall near the shop, a reef has been built off shore.
- The reef is too low, it is covered by water at high tide – this means it won’t stop the sea moving sand.
Here is a groyne where the lower part, the part sometimes covered by the sea, has sea weed growing on it.
The sea is eroding land at Seawick
EA and TDC are doing nothing
EA and TDC have already built rock groynes at Seawick which successfully defend the coast against the sea.
EA and TDC have built rock groynes at Seawick which DO NOT WORK, and done absolutely nothing to rectify the situation.
Could this be because EA plan to either knock down seawall at Seawick or let it fail? environment-agency-plan-for-tendring-coastline-by-2105-may-2013
