Abstract:
An embayment along the riverside is contributing to provide and maintain the ecological process from the environmental point of view. The connection between the primary river flow and a dead zone is often found as a closed partially partition made by sediment deposition or artificial works. It results in an entrance on the connection between main channel and the embayment zone. Effects of the length, width and location of the entrance channel were measured by PIV method in horizontal plane. The flow patterns in embayment zones were changed according to the flow and fitted to the size of the length and width of the entrance. When the length of entrance is wide relatively to the width, a large scale of primary vortex was generated and located both in the embayment and the entrance zone. The size of this vortex becomes longer in the transversal direction as the entrance length increases.
