Opis

These proceedings of the International Workshop of Fluvial Hydraulics of Mountain Region (Trent, October 1989) can be regarded as the state-of-the-art on water flow and sediment transport in mountain rivers. The focus is on: - Hydrodynamics of steep rivers; - Sediment movement and sediment control; - Particular features on sediment transport relevant to non-uniform grain-size.
