In this study recent equations for the main geometrical characteristics of hydraulic jumps are applied to experimental data of several sources, to verify the adjustment of the equations and eventual trends observed for the adjusted parameters. The equations reflect the conservation principles of mass, momentum and energy for a hydraulic jump. They are presented in non-dimensional form, and admit ad-justment through few coefficients, defined while modelling the energy dissipation in the jump. The ad-justments highlighted here are of good quality. The adjusted coefficients are analyzed in the sense to compute the effect of roughness. It is seen that this effect may be adequately quantified and that a com-prehensive study of the coefficients is welcomed for the use of the formulation as pre-design tool for hy-draulic structures like dissipation basins. Complementing the information, the shape of the surface of the air-water mixture is also discussed, considering predictive equations, in the sense of furnishing a complete picture of the geometrical properties of hydraulic jumps. Experimental and numerical results are used.
