Reservoir routing with outflow through rockfill dams

Abstract: For flood control and watershed management a model simulating the hydraulics of flow through rockfill dams is necessary. This paper describes a model for flow through rockfill dams. In the model, velocity has been introduced to the 1-D continuity equation as an exponential relationship between Reynold's number (Re) and Darcy-Weisbach coefficient (f ). The model has been calibrated by using a nonlinear optimization technique and then verified. By introducing inflow hydrograph and rockfill characteristics as inp… Show more

“…Non-Darcy and turbulent flows in coarse porous materials were considered by, for example, Wilkins (1956), McCorquodale et al (1978), and Stephenson (1979). Solutions were provided by Skjetne and Aurault (1999), Samani et al (2004), Salehi (2003), Sidiropoulou et al (2007), and Panfilov et al (2003). For a longitudinal slope of 0.01, Moutsopoulos (2009) estimated that a fully-developed turbulent flow occurs if the mean grain size of the porous medium is in excess of 30.3 mm for a porosity of 0.35.…”
