SWRC Mission:
The Southwest Watershed Research Center conducts long-term research of soil, water and climate processes to better understand interactions with plants, animals and humans as a basis for management of semiarid watersheds. SWRC develops new technologies for land managers, including remote sensing, computer-aided decision tools, and ecosystem models. |
