| description | Erosion processes of cohesive sediments in reservoirs are studied experimentally as a basic study for fine sediment management in reservoir. The relationships between their critical shear stresses and water contents are liner on log-log paper, which is the same trend as those on cohesive sediments in lakes and river mouths. The relationship between critical shear stress and water content varies in sediments and it can be estimated from its liquid limitation. Since liquid limitation mainly depends on ignition loss and median particle diameter which are usually measured by a dam administrative office every year, those data could help to discuss on erosion process of cohesive sediments in reservoir before detail investigation. |
