Geography - Groynes

Alice10

can anyone help me add on a few more SRPs to this answer because I haven't 15

Groynes are an example of how humans interact with the natural processes along a coast.
Groynes are wooden barriers built at right angles to the coast.
They interfere with the natural processes of erosion, transportation and deposition.
They are built to stop longshore drift. Longshore drift is the zig zag movement of materials along the coast.
This is necessary where silt is inclined to build up blocking access to a port.
The groynes dissipate wave energy.
The incoming swash is trapped and fored to drop its load.
Groynes stop transportation and cause deposition to occur where it otherwise would not take place.
This is shown on the following diagram....
The beach down the coast is deprived of beach material and eventually fades away. As a result erosion occurs downstream.

will someone help me please?

Also what kind of question could we get on floods/flooding ??

spurious

Can be used to 'save' beaches from washing away, thus helping tourism.
Can be made of other materials - concrete, steel etc.

Can't you talk about more than just one way in which humans interact with coastal processes???rock armour,sea wall,marram grass and gabbons.
