Devin Lynn Galloway
Devin L Galloway is a Scientist Emeritus Research Hydrologist for the USGS Water Resources Mission Area.
During the mid-1970s the emerging movement in our culture and the sciences toward understanding human impacts on our environment piqued my interests in the environmental and earth sciences. In 1978 I began my career with the USGS in Champaign-Urbana, Illinois, where I first became interested in hydrogeology and later studied hydrogeology at the University of Illinois. Since then I've worked on many hydrogeology projects while stationed in USGS offices in Colorado, California, and Indiana. Along the way I've been fortunate to work directly and indirectly on many interesting studies of national and international relevance related to groundwater availability and sustainability, and the role of groundwater in geologic processes.
My primary research interests have been in hydrogeologic processes involving 1) the compaction of susceptible aquifer systems and resulting land subsidence that accompanies groundwater depletion; 2) response of groundwater levels to stresses imposed on aquifer systems owing to volcanism, tectonics (earthquakes), earth tides and atmospheric loading; and 3) natural and human-induced perturbations in groundwater recharge and discharge. I have been engaged nationally and internationally in efforts to raise awareness and understanding of the inland and coastal subsidence caused by intense groundwater extraction. I am past Chair of the UNESCO Working Group on Land Subsidence and the ASCE Task Committee on Land Subsidence and have led many national and international workshops on monitoring, analyzing and modeling aquifer-system compaction and land subsidence.
Since retiring from the USGS (after 40+ years of service) at the end of 2018 as a Research Hydrologist with the Earth Science Processes Division, Water Mission Area, I volunteer with the USGS as Scientist Emeritus. I collaborate on hydrogeologic research with scientists internal and external to the USGS, and advise, collaborate with, and otherwise serve USGS Water Science Centers and other USGS Offices and Programs on hydrogeologic aspects of various earth-science projects and programs.

The application of satellite differential SAR interferometry-derived ground displacements in hydrogeology
The application of satellite differential synthetic aperture radar (SAR) interferometry, principally coherent (InSAR) and to a lesser extent, persistent-scatterer (PSI) techniques to hydrogeologic studies has improved capabilities to map, monitor, analyze, and simulate groundwater flow, aquifer-system compaction and land subsidence. A number of investigations over the previous decade show how theAuthorsD. L. Galloway, J. HoffmannGround water in the Anchorage area, Alaska: Meeting the challenges of ground-water sustainability
Ground water is an important component of Anchorage's water supply. During the 1970s and early 80s when ground water extracted from aquifers near Ship Creek was the principal source of supply, area-wide declines in ground-water levels resulted in near record low streamflows in Ship Creek. Since the importation of Eklutna Lake water in the late 1980s, ground-water use has been reduced and ground waAuthorsEdward H. Moran, Devin L. GallowayHydraulic characterization of overpressured tuffs in central Yucca Flat, Nevada Test Site, Nye County, Nevada
A sequence of buried, bedded, air-fall tuffs has been used extensively as a host medium for underground nuclear tests detonated in the central part of Yucca Flat at the Nevada Test Site. Water levels within these bedded tuffs have been elevated hundreds of meters in areas where underground nuclear tests were detonated below the water table. Changes in the ground-water levels within these tuffs andAuthorsKeith J. Halford, Randell J. Laczniak, Devin L.

InSAR is a powerful technique that uses radar data acquired at different times to measure land-surface deformation, or displacement, over large areas at a high level of spatial detail and a high degree of measurement resolution. InSAR displacement maps (interferograms), in conjunction with other hydrogeologic data, have been used to determine aquifer-system characteristics for areas where surfaceEffects of land subsidence in the Greater Houston Area

The East Bay Plain, on the densely populated eastern shore of San Francisco Bay, contains an upper aquifer system to depths of 250 feet below land surface and an underlying lower aquifer system to depths of more than 650 feet. Injection and recovery of imported water has been proposed for deep aquifers at two sites within the lower aquifer system. Successful operation requires that the injected waAuthorsJohn A.

Hydrologic stresses throughout the 20th century and presently (2003) have caused the depletion and degradation of our Nation’s vital ground-water resources in many areas. Management strategies have been and are being implemented to optimize use of our ground-water resources with respect to achieving sustainability while mitigating the consequences of future withdrawals. The seven case studies presAuthorsDevin L. Galloway, William M. Alley, Paul M. Barlow, Thomas E. Reilly, Patrick TucciEarthquakes-Rattling the Earth's Plumbing System
Hydrogeologic responses to earthquakes have been known for decades, and have occurred both close to, and thousands of miles from earthquake epicenters. Water wells have become turbid, dry or begun flowing, discharge of springs and ground water to streams has increased and new springs have formed, and well and surface-water quality have become degraded as a result of earthquakes. Earthquakes affectAuthorsMichelle Sneed, Devin L. Galloway, William L. CunninghamAnalysis of tests of subsurface injection, storage, and recovery of freshwater in Lancaster, Antelope Valley, California
Ground-water levels in Lancaster, California, declined more than 200 feet during the 20th century, resulting in reduced ground-water supplies and more than 6 feet of land subsidence. Facing continuing population growth, water managers are seeking solutions to these problems. Injection of imported, treated fresh water into the aquifer system when it is most available and least expensive, for laterAuthorsSteven P. Phillips, Carl S. Carlson, Loren F. Metzger, James F.

New observations of surface displacement caused by past underground nuclear tests at the Nevada Test Site (NTS) are presented using interferometric synthetic aperture radar (InSAR). The InSAR data reveal both coseismic and postseismic subsidence signals that extend one kilometer or more across regardless of whether or not a surface crater was formed from each test. While surface craters and otherAuthorsP. Vincent, S. Larsen, D. Galloway, R. J. Laczniak, W.R. Walter, W. Foxall, J.J.

Field data from Upper Geyser Basin, Yellowstone, indicate that geyser frequency is less sensitive to elastic deformation than might be surmised from a review of the literature. Earth-tide influences are not identifiable in any of the geysers we monitored. Though atmospheric-pressure influences are observed, only long-period variations on the order of 5 mBars or greater seem to influence geyser freAuthorsS. Rojstaczer, D. L. Galloway, S. E.
