Methods for the Quantitative Assessment of Channel Processes in Torrents (Steep Streams) [Hardcover]

1 Introduction
2 Flow resistance in gravel-bedded streams and torrents
3 Fluvial bedload transport
4 Debris flows
5 Magnitude and frequency of torrent events
6 General remarks on hazard assessment of channel processes in torrentsThis book presents an overview of methods to quantify channel processes in steep catchments. The understanding and the quantitative description of channel processes provides an essential basis for the planning of protection measures. Channel processes are mostly triggered by rainfall events and associated runoff processes. Apart from possible flood hazards during an intense rainstorm event, a lot of damage is often caused by fine and coarse sediment in the form of fluvial bedload transport or of a debris flow. This work mainly discusses the topics of flow resistance, bedload transport, debris flows and the relation between magnitude and frequency of torrential sediment events.

Dieter Rickenmann is a senior research scientist at the Swiss Federal Research Institute WSL, Birmensdorf, Switzerland. He has a degree as Civil Engineer from ETH Z?rich in Switzerland and a PhD degree from ETH Z?rich. In 2002 he was appointed Professor for Alpine Natural Hazards at the University of Natural Resources and Applied Life Sciences (BOKU) in Vienna, Austria. Since 2007 he is back at the Swiss Federal Research Institute WSL, focusing mainly on sediment transport processes and debris flows in steep headwater catchments.
