When a dense flow reaches neutral buoyancy in the stratified ambient fluid, it can leave the slope and enter the ambient fluid as an interflow. In this study, the effect of discharge and concentration variations on the separation angle of the dense current body at the separation point was investigated using a physical model. The results showed that for all slopes, the separation angle of the dense current body relative to the angle of the flume bed and the horizon (bed slope angle) increased

... h increasing the inflow rate of the dense current at a constant concentration and decreased with increasing the concentration of the dense current at a constant discharge. On the other hand, for all states, the angle of dense current separation with the bed was always larger than the angle of the flume bed with the horizon.
