The Beach is a shingle spit deposited over time by longshore drift. This blocks the southerly flow of the River Adur which turns east at this point and eventually meets the sea further along the coast.
These waves tend to create longshore drift currents which push deposits along the beach until it runs into the dock and breakwater, potentially destroying the purpose of the dock being built out into deeper water.
They also measured the long axis, radius and powers shape index down the longshore to determine whether longshore drift is happening and in which direction.

The annual potential sediment transport rate, generated by vessel wakes, forms approximately 25% of the similar rate caused by wind waves and is directed opposite to the natural longshore drift. This result indicates that vessel wakes, although their impact does not control the sediment transport pattern in the study area, do cause a substantial component of the overall sediment motion on the SW coast of Aegna and that their role cannot be neglected.
