Summary The river-bed variation measurements using acoustic depth observing system were conducted in the YOSHINO and FUJI rivers during flood events. The system succeeded in capturing the dynamic variation of river-bed with sufficient accuracy to detect abrupt change of river-bet by scouring. The system will facilitate integrated levee management.
