Since the force due to flow in the plung region changes from momentum to flux, so identification of characteristics of this region is very important. In this research, geometric parameters of underflow density currents in plunge region under different inflow concentration, bed slop and inflow discharge. Experiments were conducted in a flume in Hydraulic Laboratory of Water Sciences Engineering Faculty of Shahid Chamran University of Ahwaz. In the experiments, plunge depth, plunge region length and the height of the flow at the end of this region in different discharges, four different concentrations equal to 1006, 1009, 1013 and 1016 kg/m3 and three slopes equal to  8, 12 and 16% were measured. The results show that, plunge region length and the hight of the flow at the end of plunge region are functions of plunge depth.   UR - https://jise.scu.ac.ir/article_10832.html L1 - https://jise.scu.ac.ir/article_10832_607ff1faebf3cc32be8a9986bb030ca3.pdf ER -
