Synopsis

This 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.

About the Author

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 Zürich in Switzerland and a PhD degree from ETH Zürich. 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.

From the Back Cover

An important part of the risk management of natural hazards in mountain regions concerns the hazard assessment and the planning of protection measures in steep headwater catchments, i.e. torrent control and slope stabilization. Torrent processes in steep channels have their rightful place among the various alpine natural hazards and the corresponding control measures have a long tradition in the European alpine countries. In the planning and execution of such measures, professional experience has been of paramount importance. This experience was based primarily on observations made during and after hazardous events, as well as on regular field visits in the catchments of a steep headwater stream. Quantitative measurements, e.g. of the discharge and of the eroded and deposited solid materials, have been increasingly carried out only in the last decades. This set the basis to develop and improve quantitative methods to predict flow hydraulics, bedload transport and debris flows in torrent catchments. This publication 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.
