Better Assessment Science Integrating point & Non-point Sources (BASINS)


Tool Website:


BASINS is a multipurpose environmental analysis system designed for use by regional, state, and local agencies in performing watershed and water quality-based studies. Integrates environmental data, analytical tools, and modeling programs to support development of cost-effective approaches to watershed management and environmental protection, including TMDLs. The Automated Geospatial Watershed Assessment (AGWA) tool features the USDA-ARS models KINEROS and SWAT. The Kinematic Runoff and Erosion Model (KINEROS) is an event oriented, physically based model that may be used to determine the effects of various artificial features such as urban developments, small detention reservoirs, or lined channels on flood hydrographs and sediment yield. Rosgen's Bank Erosion Hazard Index has been incorporated in the pollutant loading model as PLOAD-BEHI; this model is useful for simplified analyses of sediment issues. AQUATOX receives and automatically formats output from HPSF or SWAT in order to integrate watershed analysis with the likely effects on the aquatic biota in receiving waters. The new Parameter Estimation (PEST) tool in WinHSPF automates the model calibration process and allows users to quantify the uncertainty associated with specific model predictions.

Linkage to Other Models

The BASINS environment houses numerous models; HSPF, SWAT,PLOAD

Level of Effort

BASINS framework is intended to facilitate the setup and execution of various models. Most of these can be run rapidly with standard inputs (1-2 weeks). Refinement, calibration and iteration could require many months
