Gabion steps on stepped spillways can be a suitable alternative to solid impermeable steps due to their economic advantages, ease of implementation, stability through water pressure reduction, and energy dissipation. This study explores hydraulic jum

The log-wake law for turbulent current has been developed and tested with laboratory data on turbulent flow in smooth pipes. However, flow with turbulence and vortices in a stepped spillway have not been described. Therefore, in this study, a log-wak

This study aims to determine how well the stepped spillway at Gomaspan dam performs in terms of cavity index. For this purpose, a computational fluid dynamics (CFD) code called FLUENT is used. To begin, the code was validated by applying it to the ex

Abstract Introduction: In the present study, we investigated the effect of the location and height of a three-dimensional porous obstacle (with porosity in all three dimensions) which is located on the bottom of the steps in the width of the flume an

The reservoir is an important component of hydraulic projects for supplying water to the city. For guaranteeing reservoir safe operation, stepped spillways are often used to discharge the flood from the reservoir. But under large unit discharges, cav
