Abstract
This study investigated the desilting efficiencies of a pond by using both the shaft orifice of the pond and the horizontal pipe that was connected to the shaft orifice. The experiments were conducted in a square acrylic tank. The tank featured one vertical square shaft, and the shaft had a bottom orifice that could be used for removing sediment from the tank. The shaft orifice could be installed using a horizontal pipe with three circular orifices that allowed for sediment removal. Water-flow tests without sediment were first conducted to determine the relationship between water level and discharge through the orifices. Desilting experiments were then conducted using fine sands as the pond deposit under both constant head and falling head conditions. The final topographies of scour cones formed through water flushing were used to analyze the influence of desilting arrangements and related conditions on the volume of desilted sediment and desilting efficiency.
