USDA ARS SWRC

Southwest Watershed Research Center (SWRC) scientists conduct research in collaboration with local landowners and ranchers, local government and organizations, university partners, other state, federal and international scientists and agencies.

SWRC research ranges from understanding, describing and modeling hydrologic processes to applications of technology at the field level.

Field research in support of these program areas historically has been conducted primarily at the two main SWRC instrumented research areas Walnut Gulch Experimental Watershed (WGEW) and the Santa Rita Experimental Range (SRER).
