| Abstract: | Undoubtfully there is a strong interrelationship between sediment transport and river bed dynamics. Instable river beds are the result and the reason for erosion, transport and for accumulation of bed sediments. Since the investigations of Simons & Richardson (1962) the interpretation on flow regime, bed roughness and resistance to flow is well investigated for Sandy bed material. In contrast there is a certain neglect of knowledge in the case of coarser material. The big difference between these river beds are caused by the distinctive erodibility of the coarse materials and their restricted availability. Nevertheless the regime concept is a good tool not only for the classification of many phenomena but will help to understand the dynamics of both river beds and transports of mountain torrents. |
