| Research Abstract |
These days, 2-dimentional numerical simulation of depth-averaged flow and bed variation would be useful for river management. However, it is difficult to examine either sediment conditions at the surface or the substrate structure in detail because of problems in predicting sediment behavior in a real river. Furthermore, the attributes of mixed sediment transport vary depending on physical conditions, making it difficult to describe using numerical simulations. Therefore, two series of flume experiments were firstly conducted in order to examine sediment behavior through bed composed of two size of sand. These experiments and some simulation results indicated the important characteristics of fine and coarse sediment movement for prediction of math of sediment transport.
