Abstract
Many researchers have investigated characteristics of the hydraulic jump in sloping channels, but the effect of aerated inflow on flow characteristics of the hydraulic jump has not been shown. This paper presents the effect of aerated inflow on flow characteristics of hydraulic jumps in steep sloping channels (i.e., 30 and 55 degrees). The experimental investigation reveals that the jump length is affected by the air-concentration of the aerated inflow. The length of the jump has been formulated. By considering the air-concentration in the jump, the sequent depth ratio of the jump in sloping channels has been obtained on the basis of the momentum equation.
