Salt River Valley (SRV) Regional Model
Salt River Valley (SRV) Regional Model
Model History and Timeline
SRV MODFLOW model development began in the late 1980's. Previous to the late 1980's, two groundwater models within the Salt River Valley had been developed. Thomas Anderson (1968) developed an electric analog model simulating the groundwater depletion of Central Arizona between 1923 and 1964. In 1982 Long et al. developed a USGS Trescott Model which simulated 1964 - 1977.
Since the first SRV MODFLOW release in 1994 the model has undergone several updates with the most recent update completed in 2009 (transient calibration period 1983-2006). The SRV model geology was updated in 2010 and expanded the model grid to include the Hassayampa sub-basin. The next SRV model update is currently in the initial phase of development and plans to include a simulation of steady state (circa 1900) and transient (1901-2011) conditions.
Model Location
The Salt River Valley model grid approximately 6,937 square miles and includes the greater Phoenix metro area.
