Summary | For advancement of method for evaluating impacts on river-bed variation on the basis of sediment discharge monitoring data, we implemented development of the methodology of sediment measurement by using hydrophone for bed load and analyzing of observation data. As a result of comparison between observation data of hydrophone, direct sampling and accumulated sediment in check dams, the sediment measurement by using hydrophone has applicability to measure the quantity of bed load. |
