Projekte

Indirect bedload transport measurements help to better understand how coarse solid particles are transported in steep streams (torrents) and mountain rivers. We use three different sensor types to improve the signal interpretation: geophone, accelerometer, and microphone.

This project aims at assessing the contribution of sediment erosion from steep slopes adjacent to channel beds to the sediment transport in small catchments.
