Abstract
The tree radial hydraulic jump phenomenon is
investigated on rough and smooth channel beds under
different flow conditions and different roughness
intensities. The tree surface, bed pressure, initial depth,
sequent depth, jump length, roller length and velocity
distributions were measured. The study also includes
observations of the entrained air. Statistical methods were
used to analyze the experimental data and to generate the
necessary characteristic design charts for the free radial
hydraulic jump formed on different bed roughness intensities.
A macroscopic momentum balance is applied to the
hydraulic jump control volume to derive the general equation
for the free radial hydraulic jump on rough beds. The energy
equation is used to obtain the jump energy loss.
The dimensional analysis approach is applied to develop
the relations between the variables involved in the formation
of the tree radial hydraulic jump on rough beds.
The theoretical results are compared with the
experimental data obtained from the present study for the
free radial hydraulic jump formed on different bed roughness
intensities. The theory shows good agreement with the
experimental data.
The study concluded that, the largest energy loss and
the shortest length of the radial hydraulic jump on a rough
bed occurs with relative intensity
