BASINS (Better Assessment Science Integrating point & Non-point Sources) is a multipurpose environmental analysis system designed to help regional, state and local agencies perform watershed- and water quality-based studies. A geographic information system (GIS) provides the integrating framework for BASINS. GIS organizes spatial information so it can be displayed as maps, tables or graphics.
v4.1 [Mar 7, 2013]
- The current release of BASINS is built upon the latest stable release of the non-proprietary, open-source GIS MapWindow GIS (MapWindow website Exit EPA Disclaimer). Along with the update to the underlying GIS platform, the BASINS automatic watershed delineation tools have been updated to use TauDEM version 5 from Utah State University.
- The major functionality of two utilities, GenScn and WDMUtil, have been incorporated into the BASINS user interface. BASINS 4.1 now includes DFLOW, a tool to estimate design stream flows for use in water quality studies. BASINS 4.1 is 64-bit and Windows 8 compatible.
