Abstract

A stilling basin is designed to dissipate the kinetic energy of the flow in a hydraulic jump. Sometimes an abrupt rise is introduced based on land topography and design requirements to increase the energy dissipation and to reduce the length of the jump. The main objective of the present study is to use the abrupt rise in a radial stilling basin at certain positions to create a jet flow. Experiments were conducted to investigate the effect of the relative position and relative depth of the rise on the characteristics of the jet. The results of experiments are compared with the free hydraulic jump in a radial basin of flat horizontal bed. The dimensional analysis was used to correlate the jet characteristics to the other relevant flow and rise parameters. Also Theoretical models are developed for the prediction of the relative depth and the relative energy loss of the jet. It is found that in comparison with the case of free jump in flat bed the values of the relative depth and relative energy loss are higher and the percentage of increase decrease with the increase of the rise position to the gate. It is found also that the values of relative length are lower comparing to the free jump and the percentage of decrease decreases with the increase of the rise position to the gate.
