Artificial bed load supply at the River Elbe - investigation and realization.
Faulhaber, Petra; Alexy, Matthias
River bed erosion leads to various problems for navigation, river structures, flood safety, groundwater level and flora and fauna. A feasible measure to reduce this degradation process is to compensate for the deficit of bed load by artificial bed load supply. Since 1996 field experiments have been performed to investigate the stabilizing effect of artificial bed load feeding on the river bed in the upper reaches of the River Elbe. These field experiments were accompanied by investigations with a numerical bed load transport model to improve the knowledge about how much feeding is required to stabilize the river bed.
