Abstract:

 In this paper, theoretical developments, regarding the establishment of dimensionless relationships for sequent depths ratio and relative energy loss of
hydraulic jumps are achieved in a straight rectangular compound channel These relationships were given with and without consideration of a volume force Fx, which is assimilated by analogy to Borda-Carnot’s expression The Experiment was carried out with three different values of the width ratio τy For each τy ratio, several values of inflow Froude number were considered according to the five inflow ratio depths’ values τz The experiments proved the validity of the proposed theoretical relationships The study showed the need to consider the force Fx when the ratio τy reaches the value of 05 It reveals also the practical usefulness of the compound channel in terms of energy dissipation capability compared to the rectangular channel.
