Description: Hydrologic data, including rainfall and runoff data, have been collected on experimental watersheds operated by the U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) in southern Arizona since the 1950s. The USDA-ARS Southwest Watershed Research Center makes these data accessible via a GIS-based web interface, the Data Access Project.

Description: AGWA provides an interface that is designed to run two watershed runoff and erosion models: the Kinematic Runoff and Erosion Model (KINEROS), and the Soil & Water Assessment Tool (SWAT). The interface was developed in a geographic information system (GIS) to facilitate the preparation of model inputs, and the visualization of model outputs.

Description: The WebFacilitator software is a decision support system which uses decision rules, a hierarchical system for ranking criteria, score functions and linear programming to identify preferred management options consistent with the ranking of criteria. This application is under development.

Decision Support Tools are being developed at the Southwest Watershed Research Center to:
incorporate science into the decision making process
combine decision tools, databases, models and expert opinion for improved management of semiarid watersheds
continue and enhance transfer of knowledge and technology to stakeholders, decision-makers and the public
