摘要:
The roughness of movable beds, which are deformed by the formation of sand dunes, is not constant since bed topography is dependent on flow characteristics. The relationship between the energy dissipated by the flow and its average velocity deviates, therefore, from the quadratic form generally used to express hydraulically rough flow; it is nevertheless possible to describe the general form of this relationship and then determine its exact terms using the Einstein and Engelund methods.
