Geophysics/Surveying Unit
Primary Purpose:
To gather, process, and interpret land subsidence and aquifer
storage data to help the Department better manage the State’s
water resources. The data are gathered by using survey-grade
Global
Positioning System (GPS) equipment,
gravity meters,
and Synthetic Aperture
Radar
(SAR) satellites. The data consist primarily of GPS
positions and elevations at discrete points, absolute and
relative gravity values at discrete points for depth to
bedrock and aquifer storage modeling, and broad swaths of SAR
data that cover several critical areas of the State.

Department Programs
Supported: The two
primary programs supported by the Unit are the Land Subsidence
Monitoring Program (LSMP) and the Aquifer Storage Monitoring
Program (ASMP). In addition the Geophysics/Surveying
Unit has performed surveys and supplied data to ADWR’s WQARF
Unit, the Modeling Unit, the Water Resources Section, the
Statewide and Regional Strategic Planning Sections, the Water
Resources Investigative Section, and the Office of Water
Engineering.
Collaborations:
In the past the Geophysics/Surveying Unit has worked
collaboratively with a number of outside groups to perform
projects that aid the Department in water resource management,
require survey-grade GPS measurements, gravity measurements,
or both, and are mutually beneficial to all participants
involved. These groups include:
