In this thesis the free radial hydraulic jump phenomenon is investigated experimentally under different flow conditions. The free surface, bed pressure, sequent depth and velocity distribution are measured. The study also includes the role of the entrained air. Statistical analysis is used to analyze the experimental data and regenerate the necessary characteristic design charts for the free radial hydraulic jump. The macroscopic momentum balance is applied to the expanding section to drive the general equation for the free radial hydraulic jump. The energy equation is used to obtain the jump energy loss. The same experimental procedure and theory are applied to the submerged radial hydraulic jump to study its characteristics under different submergence and operating conditions. Since the macroscopic theory does not give the flow pattern within the jump, a mathematical model based on the strip integral method of solving the integral momentum and continuity equations is developed. The mathematical model is developed first for the free rectangular jump and it is extended to simulate the free radial hydraulic jump. The model predicts the water surface profile, hydraulic grade profile, decay of the maximum velocity, variation of the surface velocity, variation of the energy coefficient (alpha), variation of the momentum coefficient (beta), sequent depth ratio, jump length and the energy loss. The mathematical model results are compared with those of the previous researchers experimental data for the rectangular hydraulic jump, and with the experimental data from the present study for the free radial hydraulic jump. The mathematical model results show good agreement with the experimental data.Dept. of Civil and Environmental Engineering.
