Salt River Valley (SRV) Regional Model

Salt River Valley (SRV) 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.

Metadata: Report No. 16 documents ADWR's 2006 update of the geologic framework of its Salt River Valley (SRV) groundwater flow model. The purpose of the geology update was to incorporate new geologic information from active growth areas within the model area, and to better define geologic interpretations throughout the model area.

• East Valley Water Forum Scenarios for the East Salt River Valley Sub-basin. An Application of the Regional Groundwater Flow Model of the Salt River Valley, Arizona. Hipke, W. Modeling Report No. 17. (April 2007) [7.7MB pdf]

Metadata:  Report No. 17 used the Salt River Valley 1983-2002 groundwater flow model to run predictive scenarios developed by the East Valley Water Forum for the East Salt River Valley sub-basin portion of the Phoenix AMA. The scenarios were designed to provide information for the development of a water management plan by the East Valley Water Forum. The three scenarios include a “business as usual” scenario, a balance between pumping and recharge scenario, and the last scenario looked at possible solutions to reducing the major cones of depression predicted by the first two scenarios.
