Abstract

The study proposes to examine, by the experimental route, the effect of roughness on the hydraulic jump length in a rectangular channel. A comparative study between the characteristics of the jump controlled by a threshold with a smooth and rough bottom is proposed. The results of this research can be applied in the hydraulic load dissipation basins of dams and also in irrigation lines, using the ability of the projection to raise the water level downstream of the flow.
