Reservoir Sediment Sluicing?Laboratory Study

Document Type: Proceeding Paper

Part of: Soil Properties Evaluation from Centrifugal Models and Field Performance

Abstract:

Experiments are being conducted in a 12.2 meter long, 0.38 meter high, 15 centimeter wide flume to examine the behavior of reservoir sediment deposits in response to sluicing. Crushed walnut shells are used to simulate sediment. Water and sediment discharges range from 1.5 to 3.0 liters per second and 150 to 300 grams per minute, respectively. Results show that both reservoir water and sediment levels can be predicted from known values of normal open channel depth, sluicegate setting, discharge coefficient, and tailwater elevation. The significance of these results are explained.
