| − | Erosion will take place on the shoreface and on the beach if the export is greater than the supply of material, this means that the level of the seabed and the beach will decrease. The deficit can be due to both cross-shore processes and longshore processes. Erosion due to cross-shore processes mainly occurs during extreme events associated with storm surge, which partially is a reversible process. 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.
