The purposes of this Coastal and Hydraulics Engineering Technical Note CHETN are 1 to summarize the effort to model a real-time reservoir flush with the U.S. Army Corps of Engineers USACE, Hydrologic Engineering Center HEC, River Analysis System HEC-RAS, and 2 to determine the models applicability for flushing applications. HEC-RAS is a one-dimensional 1D numerical hydraulics and sediment model. Reservoir flushing events generally have no historic precedent, so they cannot be calibrated. If HEC-RAS performs well on a carefully measured reservoir flushing event, it can be applied to other reservoir flushing studies with greater confidence.
