Abstract:
The jump profile measurements on sloping floor, including the jumps with positive and negative step in an open rectangular channel were conducted. A set of regressed results of experimental data for predicting the length and depth of jumps on sloping floors are proposed. Analysis of sequent depth ratio and length characteristics revealed that the negative step has advantages over the positive with respect to stability and compactness of hydraulic jump. The results in nondimensional form may provide useful information for designing the stilling basin on sloping floor downstream of hydraulic structures.
