Using different sensor types to improve the signal interpretation

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.

The Swiss plate geophone system

This project aims to further develop the Swiss plate geophone system, a passive seismic method to measure bedload transport in water courses, with a new set of controlled experiments and field calibration measurements.
