The current study aims at examining the internal flow field and the corresponding phenomena in the developing stage of forced hydraulic jumps. Experiments with a range of Froude numbers were performed by adjusting the inclination angle of the channel. A nonintrusive measuring technique, particle image velocimetry (PIV), was used in the experiments. Numerically, the weakly compressible moving particle semi-implicit (WC-MPS) method coupled with the subparticle-scale turbulence model was applied to simulate the flow phenomena. The simulation results for both flow surface profiles and velocity distributions at different sections were compared to the experimental data from the published literature and experimental data conducted in the current study. Flow phenomena showed good agreement with the numerical simulation results. Finally, the results from the experiments and simulation provided a detailed examination of the flow field during the developmental stages of forced hydraulic jumps.
