Abstract

Stepped spillways are structurally stable, resistance to water loads, and efficient. energy dissipators, but there are no clear design rules for such structures to date. In the present study, the flow characteristics over stepped spillways were investigated for three different step configurations and for different flow parameters, using physical models. Nappe flow regime over the stepped spillways was studied. A definite equation representing the onset of the nappe flow regime was developed using the experimental observations and experimental data of other researchers. In addition, the energy dissipation for the nappe flow regime was extensively investigated for different flow hydraulic parameters. The experimental observations were compared to empirical and analytical formulas of other researches. Finally, using the experimental data in addition to that of other researchers, analytical equation: have been developed and it can be used for computation purposes of the energy dissipation of nappe flow regime over stepped spillways.
