Abstract

Hydraulic jump used to dissipate excessive kinetic energy in natural water ways since the down of time. Screens fixed in the stilling basin to control the hydraulic jump location, depth and length from four decades ago. In this study, screens with a constant height and different widths with the same screen relative area (Ar=0.285) were located behind the gate at a distance of 10 cm and tested under wide variance conditions of submerged hydraulic jump. Screens with different relative widths are tested to select the best screen relative widths. The screen relative width of 1.00 had a maximum energy loss and shortest length with a minimum tail water depth of the submerged hydraulic jump. The theoretical deduced equation of the relative depth of the submerged hydraulic jump had a higher asymmetric scatter with the experimental results around the line of equality, however a good agreement was present when a correction factor was used.
