Abstract

the hydraulic jump is a phenomenon which characterizes the flow in the open channels. It can occur in the channels with rough beds making it possible to dissipate the significant kinetic energy. this work will analyze this kind of hydraulic jump producing in rough major beds for rectangular channels of compound section. the parameters influencing the length of the jump have been systematically studied [24]. the analyzes of the phenomenon were conducted using the general jump equation. the experimental data were carried out with the aim of establishing dimensional empirical approaches which vary according to the roughness imposed on the major bed. these additional approaches obtained are proposed. The results obtained showed that the rough major beds can be used to dissipate the hydraulic energies of the hydraulic jump that occurs in the stilling basins.
