Study of the semi-theoretical relation of the hydraulic jump evolving in an U-shaped channel, with rough bed

Abstract

This study has for objective to study the theoretical relation of the hydraulic jump by sill, evolving in an U-shaped channel, with a rough bed. Functional relations, in non-dimensional form, relating the jump characteristics, seeming the effect of the bed's roughness, are obtained. A comparative study with the hydraulic jump in U-shaped channel, with smooth bed is proposed.
