A Spatiotemporal Characterization of Water Resource Conditions and Demands as Influenced by the Hydrogeologic Framework of the Willcox Groundwater Basin, Southeastern Arizona, USA

In the Willcox Groundwater Basin (WGB), increasing rates of agricultural groundwater withdrawal have led to significant regional level decline, threatening basin’s long-term water resource security. Updated characterization conditions and demand is critically important for informing management efforts. We developed hydrogeologic framework WGB linked data with land cover classification provide a spatiotemporal assessment development in WGB. A correlation analysis evaluated degree association between mean annual depth-to-groundwater extent. Results this study indicate that 2008 2021, increased by 29%. The average rate change measured wells was calculated at −13.8 m 2006 2021. found strong extent, further reinforcing understanding use basin as principal driver decline. methodological employed proved simple effective way assess resources influenced geology use. outcomes critical information toward improved providing an integrated local hydrogeology, variability, changes arid inland basins such those Arizona, USA.
