It is found that the flow pattern of the density current front is of turbulent and its subsequent part of lamilar. Formulae for computing water depth and resistance at the plunging points are deduced, and the calculated results conform well to observed data. 关 键 词：Plunging section Homogeneous FLOW with hyperconcentration of SEDIMENT NON-HOMOGENEOUS FLOW with hyperconcentration of SEDIMENT Point of INFLECTION BINGHAM yield stress Effective Reynold’s number Densimetric Froude number.
