Surrogate bedload transport measurements with the Swiss plate geophone system

 

Prediction of bedload transport is important for hazard assessment and in engineering applications such as the planning and implementation of flood protection measures. Continuous and reliable measurements of this process are difficult and challenging to obtain but important to advance the understanding of sediment transport in mountain streams. The Swiss plate geophone (SPG) system is a seismic method to measure bedload transport in water courses for which considerable experience has been accumulated over the last 15 years; it has been installed at more than 20 field sites, and direct bedload samples have been collected at many of these sites for calibration purposes. The main goal of this project is to further develop the SPG system by performing new sets of controlled experiments using an outdoor flume facility in Germany and to obtain further calibration measurements at Swiss SPG field sites.
