Regional Groundwater Flow Model of the Salt River Valley, Phoenix Active Management Area, Model Update and Calibration

Managing regional aquifer systems within the arid southwestern U.S. basins requires an understanding of the extent to which aquifer recharge and withdrawal impacts the systems, both spatially and temporally. One of largest managed aquifers in Arizona is the Salt River Valley (SRV) located within the Phoenix Active Management Area (AMA). Groundwater modeling has become the primary tool hydrologists and water resource managers rely on when examining the regional impacts of future water use scenarios within the SRV.
