Embankments, levees or dikes

04. Morphological alterations

General description

Levees or dikes along a stream or river channel are longitudinal structures designed to prevent water passing from the river channel to the floodplain. Frequently river banks are reinforced and their level is raised by the construction of a bank top mound for flood control. Such bank stabilization eliminates river planform dynamics, and the addition of levees or dikes prevents lateral hydrological connectivity, which is crucial to hydromorphological complexity and the provision of diverse habitats, including refugee, for aquatic organisms.
