The plunging model of density current established in the paper introduces the modified plunging momentum coefficient,ε,and gives the quantitative relationship at plunging point between densimetric Froude number and the essentially independent parameters such as bed slope, the drag coefficient of density currents, width of channels, discharge rate of unit width, and sediment concentration.

Experimental study on the incipient plunging point of stratified flow of turbidity currents and debris flows;

The results show that,the FrP of plunge point,the plunge depths and the creeping time of plunging inflow depend on reservoir bottom slopes——the bigger the slope,the bigger FrP of plunge point while the water depth,density flow thickness and the time are smaller.
