Action to reduce any type of erosion of the river banks. Depending on the objective and hydraulic forces acting on the bank, various methods can be used, from plant engineering to heavier constructions (masonry/concrete/rock revetment, gabions, piling, etc).
Maximum bed occupied by a stream in which water flows only temporarily when the minor bed overflows during very high-flow periods (especially in the largest historical flood). Its outer limits are determined by the largest historical flood. The floodplain of the river allows the storage of overflowing waters. There is also a mosaic of habitats for many species. These habitats are also called "water dependent habitats"
