Influence of constructional elements on sediment transport

Abstract

Efforts have recently been made to renaturalize the Weißach River which had previously been regulated in a schematic, monotonous manner. During the last flood period an aggradation of sediment occurred, which may provoke an overtopping of the dams. In a hydraulic model with movable bed (scale 1:20) the existing conditions and possible improvements were studied in order to prevent further aggradations. Furthermore, fundamental investigations were made with regard to the influence of constructional measures on sediment transport and water levels.
