Full TextAbstract
Stepped spillways is a hydraulic and cost effective measure to dissipate energy of large water flows over the spillway of a dam and like other spillway types have its limitations and a measure to improve the energy dissipation effectiveness is proposed. The aim of this research is to evaluate energy dissipation in simple stepped spillways by taking into accounts some parameters by numerical method. In this study the governing equations are solved by finite volume discretization method and the standard model is used for estimating the turbulence flow. Also, structured grid is used to accommodate the well-defined boundaries and the volume of fluid method is introduced to solve the complex free-surface problem. Results of the numerical method compared well with the experimental results of the other researchers.
