Uncertainty Evaluation of Hydraulic Jumps in Open-Surface Flows

The hydraulic jump is considered to have one of the largest energy losses in the field of Hydraulics. These losses are caused during transition from super-critical to sub-critical flow conditions in the case of open-surface flows. In this study, we focus on a laboratory-scale hydraulic jump combining both experimental measurements and model simulations using theoretical arguments. The main objective is to identify, quantify, and interpret the uncertainty in both cases through key parameters, such as the (sub/super) critical depths and channel geometry, for various flow conditions, with emphasis on energy dissipation, turbulence, mixing, regime transitions, and flow stability characteristics .
