Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


On the upstream of Atago weir, Hirose River, Japan, the sedimentation phenomenon is complex due to the coexistence of the weir and channel bend. Moreover, fine sediment accumulates on the river bed notably. From the observed results, it is found that silt is the major component in the flood water and accumulates significantly in the discharge increasing stage by the backwater of the weir. From the theoretical computation considering the settling and resuspension of the suspended sediment, the cohesion of fine sediment is an important factor of the net deposition process.
