Mission                                                                                                                     

The Arizona Department of Water Resources (ADWR) encourages the intelligent, long-term management of the state's groundwater and surface water resources through understanding the potenial impacts of local and regional aquifers.

  Purpose                                                                                                                    

Groundwater flow modeling is a tool that can be used to simulate the past, present and future impacts of water uses on aquifers.  Groundwater modeling has become an important tool in the management of Arizona’s water supplies, particularly in meeting the goals of 1980 Groundwater Management Act’s goal of achieving Safe Yield in Active Management Areas (AMAs).  Ground-water modeling allows water resource planners to make long-term management decisions based on the potential impacts of future water uses on the state’s groundwater resources.

  Modeling Basics                                                                                                      

Curious as to how groundwater models function and what they represent? Take a look at the Modeling Basics page for an explanation of the different types of models used to simulate the Arizona's water supply. The Modeling Basics Site is currently under construction.

  ADWR Models                                                                                                          

The Modeling Unit develops regional models to simulate Arizona's water supply and the future demands it may encounter. The regional models developed by the modeling unit include: Prescott , Salt River Valley, Santa Cruz, Tucson, Pinal, San Pedro, and the Yuma model.

  Providing ADWR with Measured Data                                                                  

The Modeling Unit is always looking for additional measured data in support of model development. If you have any measured data such as aquifer tests, geologist's logs, or geophysical logs please contact the Modeling Unit at modeling@azwater.gov
