Density current is one of the most important phenomena that affect sediment processes and water quality in reservoirs and other water resources. Variation of cross sections in natural channels is inevitable and affects hydraulic parameters of density currents. The recent study evaluates the water entrainment of density currents in converging reaches. The experiments were conducted in a flume with 6.0 m length, 60 cm depth and 72.5 cm width by using three converging degrees (8, 16 and 25) and with different discharges and concentrations in hydraulic modeling laboratory of Shahid Chamran University of Ahwaz. Equations were formulated to estimate the water entrainment in converging reaches with different angles and finally an equation was proposed for converging, constant and diverging reaches using experimental data which were gathered from other researchers.
