The SWRC operates the Walnut Gulch Experimental Watershed in southeastern Arizona as an outdoor laboratory for studying semiarid rangeland hydrologic, ecosystem, climate, and erosion processes. Access our data using our DAP web application.
The Walnut Gulch Experimental Watershed is part of the Long-term Agroecosystem Research Network
