Work Begins On Seawick sea defences – Oct 2020

Sand has been eroded at Hutley gap, allowing the sea to erode the sea wall and potentially flood the holiday camp. Work aimed at preventing this has started

Rock groynes were built at Seawick around 1998.  5 groynes were placed about 90 paces apart and have good beaches, 1 groyne was 180 paces away with a reef at about 90 paces. The beach here has eroded.   

Sadly it seems the plan is to build revetments (pile rocks against the sea wall) instead of replacing the reef with a groyne.

I strongly suspect this will not work.

A beach where the groynes are about 90 paces apart. You can see there is dry sand in front of the sea wall. This stops the sea from eroding the wall.
This photograph was taken within a minute of the one above. In the photo above the sea is at the sea wall, in the photo below the sea is tens of years from the sea wall. Yet only 1 groyne, a yard or 2 wide, separates these beaches.

Google images show how the sand has been eroded since the groynes were built, but only were the reef is.

This photo, from Mike Page around 2014, show the only place where the sand has been eroded (allowing the sea to attack sea wall) is at Hutley’s were the reef is.

Is it logical to think if there was a groyne here instead of a reef the erosion would have been reduced if not stopped?

This is what Environment Agency has to say.

EA has been monitoring and reporting on the coast for example

but doesn’t appear to notice the difference between where there are groynes and reefs.
