{{Definition|title=Coastal erosion
 
|definition= Coastal erosion is the process of wearing away material from the [[Shoreface profile|coastal profile]] due to imbalance in the supply and export of material from a certain section of the coast.

==Notes==
 
Erosion takes place on the [[shoreface]] and on the [[beach]] if the export is greater than the supply of material, meaning that the level of the seabed and the beach will decrease. The deficit can be due to both cross-shore processes and longshore processes. It manifests itself in the scouring in the foot of the cliffs or in the foot of the dunes. Coastal erosion occurs mainly during strong winds, high waves and high tides and [[storm surge]] conditions, and results in coastline retreat. Erosion due to cross-shore processes is a (partially) reversible process (see [[Dune erosion]]). The rate of erosion is correctly expressed in volume/length/time, e.g. in m<sup>3</sup>/m/year, but erosion rate is often used synonymously with coastline retreat, and thus expressed in m/year. The most important reason for long-term erosion is a deficit in the littoral drift budget, which is often caused by a deficit in supply of sand to the area in question (also referred to as [[structural erosion]]).
