As for the inflow of the fluid which has the different density from the stagnation area, diffusion and mixing occur with the buoyancy and shear force of inflow fluid. In this study, the reservoir model equipment was employed to examine the effect of inflow mouth angle on the behavior of the density current and the flow characteristics in circulation and mixing. The plunge flow was influenced by the inflow fluid and the densimetric Froude number Fre. Changes in the inflow mouth angle with keeping small density layer thickness did not vary the plunge point. It was found out that the thickness of the density layer was not influenced by time but only influenced by Fre. The changes in the density and the fluid reflected at the end of the downstream in the reservoir are expressed as functions of the reservoir length, time and the buoyancy flux.
