Strip of natural vegetation located along a river, and which differs from the surrounding matrix, including the river bank, the floodplain and part of the alluvial terraces. The presence of a stream or wood is not enough to make corridors. It is their conduction function that defines them. At the regional level, the riparian corridor appears to be a relatively uniform area (line of trees). At the local level, sedimentary and hydrological constraints provide variability of conditions resulting in a mosaic of habitats. The corridor is a transition zone between the water system and terrestrial system. Thus,…
For a river, to ensure the free movement of species (in particular fishes) and the smooth flow of sediments.
Is defined by the free circulation of biological species and good flow of natural river sediment transport. The concept of ecological continuity did not take sediment transport into account until the Water Act of 2006.
