Preliminary Experiment on Reservoir Sediment Flushing

Prediction of reservoir sediment flushing requires a large amount of sample data obtained from long-term field measurements. Before running the complete laboratory experiments to understand the flushing mechanism, preliminary experiments using an acrylic tank and a simple piping system were carried out. The acrylic model consists of a constant head tank and a reservoir model. The constant head tank is a model that ensures a continuous and consistent flow rate contribution to the next model component, namely the reservoir model. The Reservoir model is a component for modeling the sediment flushing process, where the sediment deposits have been prepared. The reservoir sediment flushing experiment used a bottom outlet with a circular hole connected by a pipe to a valve to release sediment. The valve is assumed to be a sluice gate that can be opened and closed for sediment flushing. Preliminary experiments show that the model can simulate the flow of reservoir sediment flushing through the bottom outlet with stable reservoir water depth, operation of sluice gates, and the presence of scour cones in the sediment.
