Final Report Abstract

The results achieved within the project “Surrogate bedload transport measurements with acoustic sensors” will be useful: to continuously monitor the total and fractional bedload transport activity in torrents and rivers at the four example sites in the Swiss Alps Albula, Navisence, Avançon de Nant and Erlenbach in the coming years, allowing further and detailed process-based studies of bedload transport in mountain catchments; to plan future field and flume calibration campaigns involving bedload surrogate monitoring systems; to further improve the design of such systems and to develop general calibration relationships for other monitoring systems based on impact structures.
