Abstract
ABSTRACT The dam is one of the most prominent hydraulic constructions on the world. Sediment flows into dam reservoirs because of human involvement in the dam catchment region, eventually affecting its functional storage. Density currents are a key feature of sedimentation. The use of bottom outflow gates to preserve the reservoir’s usable volume is one approach of mitigating the effects of sedimentation. This could have an effect on the quality of the water as it exits the dam. The purpose of this research was to see how well salt current from lock exchanges was vented at different levels and outlet gate sizes. Based on the latest study’s experiments, this is the highest venting efficiency when the location of outlets is in the quarter of the bottom of the dam. The output concentration will be equal to the average concentration of the concentrated input current, which is the best height for installing the outlet gates, based on the maximum venting efficiency demonstrated in the recent study’s experiments, which may be described as the best height for the turbidity current outlet gate. Discharge efficiency increases when the intake concentration is lower.
