Welcome to the U.S. Army Corps of Engineers Statistical Software Package (HEC-SSP) developed by the Hydrologic Engineering Center.  This software allows you to perform statistical analyses of hydrologic data.  The current version of HEC-SSP can perform flood flow frequency analysis based on Bulletin 17B, “Guidelines for Determining Flood Flow Frequency” (1982), a generalized frequency analysis on not only flow data but other hydrologic data as well, and a volume-duration frequency analysis on high and low flows. 

The purpose of this site is to enhance the support services we provide to our customers. We've provided a number of resources here to help you download software, resolve problems, report bugs, and suggest improvements to our products and service.
