| Abstract: | Energy dissipation by hydraulic jump is widely used in various hydraulic profects.Generally the end sill is adopted in the stilling basin.Previous studies on the effect of impact force on the end sill by hydraulic jump were conducted by model experiments or by empirical equations.In this paper,the effect of impact force on the end sill is investigated by momentum theory.The results are compared with those of the design criterion. |
