Development of drop number performance for estimate hydraulic jump on vertical and sloped drop structure

Hydraulic jumps primarily serve to dissipate the excess energy of flowing water downstream of hydraulic structures, such as spillways, weir, sluice gates etc. This type of jump is of practical importance when tail water depth is inadequate to give a good jump. The research conducted at the hydraulic...
