The SITES Integrated Development Environment (IDE) for Water Resource Site Analysis has evolved significantly, developed by NRCS over 25 years. This software incorporates advanced technologies for spillway erosion analysis, created jointly by ARS and NRCS, and continues to improve for better user experience. Key features include watershed rainfall-runoff, streamflow routing, reservoir routing, and assessments of principal and auxiliary spillway ratings. The recent update, version 2005.1.4, enhances its functionality for engineers and resource managers.
