ADWR’s Hydrology Division provides technical hydrologic support to the Water Management, Surface Water, and Statewide Water Planning Divisions.  The Hydrology Division has three primary functions:  to collect data statewide, to perform hydrologic analysis of permit applications, and to provide analytical tools such as groundwater models for use in supporting water management decisions.

Field Service Section                             

The Field Services Section provides support in making water management decisions by collecting, analyzing, and interpreting hydrologic data.  This section is comprised of the Basic Data unit and the Geophysics/Surveying Unit.

Geophysics/Surveying Unit

Technical Support Section                   

This Technical Support Section provides support in making water management decisions by developing groundwater models, performing GIS analysis of hydrologic data, and providing support to ADEQ's water quality programs. The Water Quality Unit reviews well construction to assure that land and water users are protected from potential vertical cross-contamination within wells and plume migration.

Water Resources Section                    

The Water Resources Section (WRS) provides technical reviews of hydrologic data and reports related to the following types of permits and applications: assured and adequate water supplies, well impact analyses, artificial recharge projects and Water Protection Fund grants. The WRS conducts these reviews in support of Water Management and other ADWR Divisions.
