Abstract

This paper illustrates the main features of the hydraulics of mountain streams. The effects of small submergence and riverbed steepness on sediment motion initiation and transport are discussed together with the effect of big roughness elements and pool-riffle and step-pool sequences on velocity distribution and flow resistance. Finally, the most used torrent defense techniques are described.
