| Abstract | ||||
| The effect of using stilling basins on local scour phenomena, which occur downstream irrigation structures, was conducted out in the laboratory of irrigation and hydraulics, Faculty of engineering EL - Mansoura University.Experiments were carried out for different gate openings, flow conditions, and dimensions of stilling basins, using two types of sand as bed material. This research was performed for Froude number ranged from 0.26 to 0.45 for selected dimensionless relationships between the design parameters.Empirical relationships between the dimensions of stilling basins, flow conditions, bed material and scour hole parameters were developed from dimensional analysis technique based on the data obtained from the experimental tests.Generally, the obtained results showed good Fitting between the different parameters. The results indicated that the dimensions of the scour hole were affected by Froude number downstream the sluice gate. | ||||
