Abstract

This course focuses on the various transport processes in torrents. This includes discharge, bedload, debris flow, and large wood. Special focus will be put on discussing recent research articles on the various transport processes.

Objective

At the end of the course, the students will be able to: (1) Describe the different transport processes in torrents, such as flow discharge or bedload transport, (2) discuss how these processes affect the resulting natural hazard, and (3) derive solutions for a sustainable hazard management.

Content

The first part of the lecture introduces the different transport processes in torrents such as discharge, bedload, debris flow, and large wood. This will include methods to determine and calculate the discharge, characterize debris flow, and quantify wood load. In the second part of the lecture, special focus will be put on the implications of the transport processes on the resulting natural hazards. The last part of the lecture focuses on the design of countermeasures such as check dams and will include examples from selected catchments in Switzerland. Two field trips are planned to illustrate the transport processes and existing countermeasures.
