Slide13:
How do these features help
to protect the coast? The concave sea wall reflects back the wave energy that would otherwise erode the soil behind the wall. The steps slow down the waves to reduce their energy before they hit the curved wall. The rock armour slows down the bottom of the waves causing them to break early. A cubic metre of sea water weighs a tonne. At 50 km/hr how much force will 1 tonne of water exert? Severn Beach
Slide14:
Should this part of Severn Beach have coastal defences at all? Yes
To stop the fields being eroded.
To give tourists a dry walkway.
To keep builders in work. No
A wall here means erosion elsewhere.
The land behind is not that important.
To keep a natural habitat for wildlife
