Research Abstract |
Erosion characteristics of cohesive material bed by non-cohesive material is clarified by flume tests and the relationship between sediment size distribution and bed hardness is verified by field observation. Furthermore, effect of cohesive characteristics on geometric and migration characteristics of channel and bed configurations is discussed. Finally, the bed deformation model with vegetation dynamic states was developed.
