  • Abstract en This study aims to estimate sediment discharge and river bed variation based on long-term hydraulic quantities in a basin. For comprehensive sediment management throughout the river basin, it is important to elucidate sediment dynamics, such as the sediment yield from the mountains and sediment transport in the river not only during flood periods but also during normal periods. We formulated non-uniform sediment discharge from the mountainous area by using the long-term hydrologic cycle model. In addition, we performed long-term calculation of river bed variation, using the formulated equations as boundary conditions at the upstream end of the Mu River basin, Hokkaido, a river with high sediment yield. We reproduced the long-term trends of river bed variation and succeeded in estimating the sediment discharge into the estuary.
