| Research Abstract |
Various configurations were considered as concavity spaces for improving ecological environment in rivers. The effects of their boundary conditions on flow behaviors and sediment transport were investigated by field observations, laboratory experiments and numerical simulations. As to the riverside embayments, flow characteristics and sand deposition mechanism were clarified with respect to the configuration process of embayments and flow stage. The important points were indicated for creating pools and river course diversity by using permeable groynes and boulders.
