Abstract

Recently, the non-prismatic stilling basins attracted many researchers due to their effective dissipation of excess energy. Radial stilling basins are characterizing with symmetric flow patterns that in turn minimize the expected damages of the erodible bed downstream the stilling basins. In this research, the submerged flow in radial stilling basin was provided with negative step and an end sill was analyzed both theoretically and experimentally. The effects of various parameters such as submergence, relative height of sill, relative height of step and inlet Froude number were presented and discussed. The experimental study is conducted on 30 cm wide, 45 cm deep and 12 m long open channel. The theoretical study utilized the one-dimensional momentum and continuity equations. The developed equations are verified using the obtained experimental data. Also, prediction models to estimate the length of jump are developed using the dimensional analysis and statistical methods. The models are calibrated and verified using the experimental data.
