Experimental study of the hydraulic jump in a hydraulic jump in a sloped rectangular channel

S. Kateb, A. Ghomri, M. Debabeche

Abstract


The hydraulic jump in a sloped rectangular channel is theoretically and experimentally examined. The study aims to determine the effect of the channel’s slope on the sequent depth ratio of the jump. A theoretical relation is proposed for the inflow Froude number as function of the sequent depth ratio and the channel slope. An experimental analysis is also proposed to find a better  formulation of the obtained relation. For this motive, five positive slopes are tested. The relations obtained are recommended for designing irrigation ditches.


Keywords: Hydraulic jump; rectangular channel; positive slope; open channels;  irrigation ditches.
