Abstract

Sediment monitoring has been started at a branch of the Sumiyoshi River in Rokko Mountains. Rainfall, water level, bedload discharge and turbidity are measured. Bedload discharge rate are measured continuously with a hydrophone and a pit (slit) bedload sampler. Pressure pillows are used to measure the weight of trapped bedload in a pit on a torrent bed. The pit bedload sampler was adopted for the calibration of the hydrophone. They have worked properly and water and sediment monitoring were successful. The hydrophone's data were converted into instantaneous bedload discharge with the pit bedload sampler's data.
