Transport Processes in Torrents

Does not take place this semester.

Abstract

This course focuses on the various transport processes in torrents. This includes discharge, bedload, debris flow, and large wood. Differences between transport processes in rivers versus torrents will be discussed. Special focus will be put on the (1) analysis of the interaction between the transport processes (cascading processes) and the (2) design of countermeasures.

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 cascading 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 cascading effects (what happens if multiple transport processes occur at once) and their implications 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.
