Natural processes of coastal erosion 1 strong waves and high wind play a most important role in coastal erosion while the waves strike the.
The aim of coastal policy is to mimic nat- ural processes by balancing erosion and accretion, principally through 'beach nour- ishment', that is, replacing sand.

These include: tsunami, storm surge, high winds, coastal erosion, sea-level rise, and high wave overtopping building on eroding coasts increases vulnerability.
A geographical coastal feature is a physical manifestation of processes operating upon a shoreline component: currents operating on sand, tides upon shores. The movement of sediment along the coast and the loss and gain of shoreline— erosion and accretion—are continuous and interrelated processes.
