Abstract: Hydraulic jump on horizontal bed of a rectangular channel is treated as a plane turbulent wall jet of an incompressible fluid of finite width in adverse pressure gradient. Momentum integral techniques have been applied to determine the longitudinal variations of the parameters characterizing the assumed mean velocity distribution. The kinematic constraint arising from the requirement of continuity has been imposed. The idealized wall jet has been modified to take into account the mean velocity distribution ahead of the jumps that is typical of most of the experimental situations. The mean flow properties of jumps at high Froude numbers, e.g., the maximum velocity, surface velocity and depth profile, are predicted and compared with experimental results.
