The Watershed Analysis Tool (HEC-WAT) software is a tool that streamlines the analytical and reporting processes of software commonly used by the multi-disciplinary teams in Corps offices for water resources studies. The WAT accomplishes this through a common graphical user interface in the PC environment. The WAT is able to integrate various pieces of software knowing little about the individual software's code.
