Streamflow Synthesis and Reservoir Regulation Model

The Streamflow Synthesis and Reservoir Regulation (SSARR) Model was developed to provide mathematical hydrologic simulations for systems analysis as required for the planning, design, and operation of water control works. The SSARR Model has been further developed for operational river forecasting and river management activities. As a general purpose mathematical model of a river system, the SSARR Model is a useful tool for streamflow and runoff forecasting, as well as for long term studies of the hydrology of a river system. Numerous river systems in the United States and abroad have been modeled with the SSARR Model by various agencies, organizations, and universities.

Please read the Conditions of Use that apply to computer programs furnished by the U.S. Government. The SSARR files consist of one ZIP file with the SSARR program, source code and examples (730KB), and one PDF file with the SSARR documentation (43MB). The pkunzip.exe program is also provided for your convenience. This version of SSARR was modified in 1991 to run on IBM-compatible personal computers. There will be no further program updates or modifications to the SSARR files by NWD-NP, and no user support is available.
