Abstract
T
he hydraulic jump is a phenomenon which characterizes the flow in the open channels. It
can occur in the channels with rough beds making it p ossi ble 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 s tudi ed . the analyzes of the phenomenon were conducted
using the genera l 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. the s e ad ditional approaches obtained are proposed. The results
obtained sh owed that the rough major beds can be used to dissipate the hydraulic energies of
the hydraulic jump that occurs in the stilling basins.
