Synopsis

In this paper a simple, practical and quick method is presented to indirectly predict the total boundary shear force along a free sloped hydraulic jump, in a rectangular channel with inclination angles 0^o<φ<16^o and Froude numbers 2<Fr₁<16. The method compares the present results with previous data based on the laboratory and the onedimensional momentum equation. The comparison shows small differences, i.e. the method is considered as successful, and may help the hydraulic engineer when designing any pertinent stilling basin – sloped or horizontal.
