ADWR Groundwater Modeling Section

Groundwater flow modeling is a tool that can be used to simulate the past, present and future impacts of water use on aquifers. Groundwater modeling has become an important tool in the management of Arizona’s water supplies, particularly in meeting the 1980 Groundwater Management Act’s goal of achieving Safe Yield in Active Management Areas (AMAs). Groundwater 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.
