Hydraulic jump in sloping channel with positive or negative step

Abstract

Predictive mathematical models of hydraulic jump in rectangular sloping channels with a positive or negative step are presented. The models are verified with experimental data. A generalized equation for the modified Froude Number which accounts for channel slope and step height is suggested which is applicable to sloping channels with or without a step. A practical method for the determination of the sequent depth is presented and some important characteristics of the hydraulic jump in sloping channels with a step are also studied.
