BASINS 4.0 Climate Assessment Tool (CAT): Supporting Documentation and User's Manual (Final Report)
EPA is announcing the release of the final report titled, BASINS 4.0 Climate Assessment Tool (CAT): Supporting Documentation and User's Manual. The document was prepared by the National Center for Environmental Assessment within EPA’s Office of Research and Development.
The U.S. Environmental Protection Agency’s Global Change Research Program (GCRP) is an assessment-oriented program within the Office of Research and Development that focuses on assessing how potential changes in climate and other global environmental stressors may impact water quality, air quality, aquatic ecosystems, and human health in the United States. The Program’s focus on water quality is consistent with the Research Strategy of the U.S. Climate Change Research Program—the federal umbrella organization for climate change science in the U.S. government—and is responsive to U.S. EPA’s mission and responsibilities as defined by the Clean Water Act and the Safe Drinking Water Act. A central goal of the EPA GCRP is to provide EPA program offices, Regions, and other stakeholders with tools and information for assessing and responding to any potential future impacts of climate change.
In 2007, the EPA Global Change Research Program (GCRP), in partnership with the EPA Office of Water, supported development of a Climate Assessment Tool (CAT) for version 4 of EPA’s BASINS modeling system. This report provides supporting documentation and user support materials for the BASINS CAT tool.
Specifically, BASINS CAT provides flexible capabilities for creating climate change scenarios allowing users to quickly assess a wide range of what if questions about how weather and climate could affect their systems. BASINS CAT does not provide climate change data for specific regions and watersheds. Combined with the existing capabilities of HSPF for assessing the effects of land-use change and management practices, BASINS CAT can be used to assess the coupled effects of climate and land-use change, and to guide the development of effective management responses.
The purpose of this report is to provide documentation and user support materials for BASINS CAT. The report is composed of 8 chapters. Chapter 1 is an Executive Summary, and Chapter 2 an introduction to BASINS CAT. Chapter 3 provides a narrative description of the basic capabilities of BASINS CAT. Chapter 4 is an overview of the BASINS CAT interface. Chapter 5 provides a set of detailed tutorials illustrating how various tasks are completed using BASINS CAT. Chapter 6 summarizes a case study application of BASINS CAT assessing the potential impacts of climate change on a mid-Atlantic watershed. Chapter 7 lists some supporting resources where users can go for additional information about climate change, and Chapter 8 lists references cited throughout the report.
