To compare responses of bedload measured by the pipe hydrophones and plate geophones, both sensors are installed at the same sites in the Ashiarai-dani, Japan and the Erlenbach, Switzerland. Contemporaneous sensor and bedload data were obtained during the rainfall events. From the results, responses from the hydrophone and geophone sensors show liner relationship, however, the sensitivity for smaller sediment by the hydrophone is higher than geophone. It is suggested that the combination of both sensors is a appropriate method of bed load monitoring.
