A review study on the effect of artificial bed roughness on the performance of prismatic hydraulic jump stilling basins

Hydraulic jumps offer an efficient method of dissipating excess kinetic energy beneath hydraulic structures such as chutes, spillways, and gates. Typically, the performance of a hydraulic jump stilling basin is measured in terms of the jump features it assigns: the basin must be both efficient in terms of energy dissipation and economical in terms of financial considerations. Corrugated and roughened beds are an alternative to the smooth beds commonly used in hydraulic jump stilling basins, and the effects of artificial roughness and corrugated beds on the performance of hydraulic jump stilling basins with respect to energy dissipation and jump length are thus reviewed in this study. Rough beds were thus found to have significantly higher shear stress than smooth beds, making them superior to smooth beds in terms of reducing basin length and enhancing energy dissipation.
