AGWA 2.0- TMDL Fact Sheet

Watershed 1.5

What is AGWA?

The Automated Geospatial Watershed Assessment (AGWA) tool is an interface designed to run two watershed runoff and erosion models: the Kinematic Runoff and Erosion (KINEROS) model, and the Soil and 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.

How can AGWA help with TMDLs?

  • Locating potential impairment
    • AGWA can quickly and inexpensively identify and prioritize problem areas at the basin and watershed scales
  • Evaluating the impacts of land-use change
    • AGWA can evaluate where water-quality impacts of past and future landscape change are most significant
    • AGWA includes a land-cover modification tool to assist with scenario development
  • Mapping results
    • All model outputs for both streams and upland areas can be mapped to facilitate comparisons with other data layers and the presentation of results

 

Where can I get AGWA?

AGWA example datasets, training exercises, and documentation can be downloaded via the Internet free of charge from:
www.tucson.ars.ag.gov/agwa or www.epa.gov/nerlesd1/land-sci/agwa
