Hydrology Division
ADWR’s
Hydrology Division provides technical hydrologic support to the Water
Management, Water Engineering, 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.

Data Collection
The Basic Data and Survey Units collect groundwater,
surface water, GPS and gravimetric information that is used when
submitting applications for water supply and recharge projects, for
developing water budgets, hydrologic models, hydrographic survey reports,
land subsidence evaluations, Indian water rights settlements, water rights
decisions, well drilling application review, water quality assessments, in
review of recharge applications and ongoing evaluations of recharge
facility performance, and for a variety of special projects.
Reports, maps and data collected by the Division are available through the
e-Bookstore.
Basic
Data Unit
The Basic Data Unit is the Arizona Department of Water
Resources primary source of groundwater data. Basic Data (BD) is
responsible for collecting groundwater levels and some water quality data
throughout Arizona.
Field Services
Includes
Transducer
Project and Data Search information.
Geophysics/Survey
Unit
The Geophysics/Surveying Unit gathers, processes, and
interprets land subsidence and aquifer storage data to help the Department
better manage the State’s water resources.
Permit Analysis
The
Hydrology Division provides technical reviews for applications for
Assured and Adequate Water Supplies, for well impact studies, and for
groundwater recharge projects. Two sections provide these services in
support of Department Water Management programs.
Water
Resources Section
The Water Resources Section reviews application for an
Assured Water Supply (AWS) with
in
Surface
Water and Recharge Section
The Surface Water and Recharge Section
provides hydrologic reviews of applications for groundwater recharge
projects, recharge recovery well applications, in-stream flow
applications, and certain determinations of surface water rights.
Technical Support
Section
This section provides support in making water management decisions by
developing groundwater models, performing GIS analysis of hydrologic data,
and providing support to ADEQ in remediating certain types of wells.
Groundwater
Modeling
The Modeling Unit has developed and used models for the Active Management
Areas of the state and for several other areas as well. Older reports are
available through the
Bookstore, while new reports are below.
Santa Cruz AMA Groundwater Flow Model - ADWR has developed a regional groundwater flow model of
the Santa Cruz Active Management Area that covers a stretch of the effluent-dominated Santa Cruz River in southern Arizona.
The
model was developed as a tool
to better understand the complex and interdependent stream-aquifer system, and
to provide guidance for the management of regional water resources. Water management topics relevant to the Santa Cruz AMA include bi-national water
issues and the reliability of water
Ground-Water Occurrence and Movement, 2006, and
Water-Level Changes in the Detrital, Hualapai, and
Sacramento Valley Basins, Mohave County, Arizona. (Scientific Investigations Report 2007–5182)
Detrital, Hualapai, and Sacramento Valley Basins are broad, intermountain desert basins in Mohave County, northwestern Arizona, and are home to residents in the City of Kingman and several rural communities. The spatial extent of these basins is defined by the Arizona Department of Water Resources’ (ADWR) ground-water basin boundaries. Ground water is the primary source of water in these basins and is essential for many economic and cultural activities. As in many parts of the western United States, population growth in these basins is substantial.
WQARF/Technical
Support
The Technical Support Unit provides support to ADEQ’s WQARF
program by performing field surveys of selected WQARF areas and
identifying wells with a high probability of allowing continued
contamination of the groundwater system. ADEQ prioritizes these
wells for remediation or abandonment.
