Background

The Office of Research and Development, in partnership with EPA’s Office of Water, recently developed a Climate Assessment Tool (CAT) for the Office of Water’s BASINS 4.0 watershed modeling system. BASINS CAT provides a flexible set of capabilities for modifying historical weather data to create climate change scenarios for assessing the influence of climate variability and change on water quantity and quality using the Hydrologic Simulation Program – FORTRAN (HSPF) watershed model. This report provides technical information including a discussion of tool capabilities and a set of hands-on tutorials intended to support BASINS users interested in applying the CAT tool.
