Processes:

- Longshore drift was accused, the movement of material along a coast by waves which approach at an angle to the shore but recede directly away from it.

- Attrition was one as well, it's a form of coastal erosion. Rocks are transported downstream along a riverbed.

- Deposition was one of the processes, deposition is a geological process in which sediments, soil and rocks are added to a landform or land mass.
