SedSim: A River Basin Simulation Screening Model for Reservoir Management of Sediment, Water, and Hydropower

SedSim is an open-source modelfor simulatingwater and sediment flows, and hydropowerproduction, in networks of reservoirs and river channels. SedSim enables water resources systems analysts and planners to explore alternative system configurationsof reservoir sites, designs (i.e., dam outlet structures), and operating policies (SDO), and their implications for water flows, sediment transport, reservoir sediment trapping, and hydropowerproduction in any river basin. The modelenables simulationof a wide range of reservoir sediment management techniques, including flushing, sluicing, density current venting, bypassing, and dredging. The source code is written in the Visual Basicfor Applications(VBA) language. The model is freely available at www.github.com/FeralFlows/SedSim . Funding statement: The development of this model was supported by the Natural HeritageInstitute through U.S. Agency for International DevelopmentCooperative Agreement AID-486-A-11-00002.
