Modeling Sediment Concentrations during a Drawdown Reservoir Flush: Simulating the Fall Creek Operations with HEC-RAS
Stanford Gibson and James Crain
This U.S. Army Corps of Engineers (USACE) Regional Sediment Management Technical Note (RSM-TN) summarizes the history and objectives of the Fall Creek reservoir flushing operations and presents a one-dimensional (1D) morphodynamic model that simulates sediment dynamics during the flush. A USACE Institute for Water Resources (IWR), Hydrologic Engineering Center, River Analysis System (HEC-RAS), model was developed to simulate sediment flushing and was compared to downstream flush concentrations for three separate years (2012, 2013, and 2014).
