INSTANTANEOUS SEDIMENT CONCENTRATION DUE TO WAVE ACTION AT PROTOTYPE SCALE

Klemens Uliczka

Abstract


At sandy coasts the sediment transport due to wave action can cause beach erosion and loss of protecting dunes. In order to calculate the wave-induced sediment transport the physical parameter of wave height, waveinduced current, instantaneous sediment concentration and bottom elevation have to be known or measured. The following study was concerned with field measurements and extreme conditions (wave-induced sheet-flow transport), which were simulated at prototype scale in the Large Wave Flume (GWK) in Hannover.
