    O.E. MEINZER AWARD Presented to Bridget R. Scanlon Phoenix, Arizona, USA 24 September 2019 Hydrogeology Division The Geological Society of America Bridget R. Scanlon Bridget Scanlon, a senior research scientist at the Bureau of Economic Geology, The University of Texas at Austin, received her B.S. in geology from Trinity College (1980), her M.S. in geology from the University of Alabama (1983), and her Ph.D. in geology from the University of Kentucky (1985). Currently leading the Sustainable Water Resources Program at the Bureau, Bridget’s areas of expertise include evaluation of the impact of climate variability and land use change on groundwater resources; application of numerical models for simulating variably saturated flow and transport; and assessment of natural and anthropogenic contamination of aquifers, including arsenic and nitrate. Among the many awards and honors Bridget has received are the Bureau of Economic Geology Publication Award for exemplary publication of scientific or economic impact (2009); the Joseph C. Walter Jr. Excellence Award, Jackson School of Geosciences (2008); the Geological Society of America Birdsall- Dreiss Distinguished Lecturer (2007); the Conservation Award, Barton Springs Edwards Aquifer Conservation District (2000, 2004); the George F. Pirtle Award, Department of Geology, University of Kentucky (1984); and the Mining and Mineral Resources Research Fellowship, University of Alabama (1982–1983). She is a fellow of the Geological Society of America and of the American Geophysical Union, and she has served on many committees and in many editorial positions. O.E. MEINZER AWARD I am delighted to introduce Bridget Scanlon as the recipient of the 2019 O.E.

The purpose of this study was to evaluate two different equivalent porous media approaches: lumped and distributed parameter, for simulating regional groundwater flow in a karst aquifer and to evaluate the adequacy of these approaches. The models were applied to the Barton Springs Edwards aquifer, Texas. Unique aspects of this study include availability of detailed information on recharge from stream-loss studies and on synoptic water levels, long-term continuous water level monitoring in wells throughout the aquifer, and spring discharge data to compare with simulation results. The MODFLOW code was used for the distributed parameter model.

  • Tracking Water Storage Shows Options for Improving Water Management During Floods and Droughts 19 August 2021
    Tracking water storage shows options for improving water management during floods and droughts 19 August 2021 western U.S., there is rising concern about overtaxing water resources in the region, especially for irrigated agriculture. "It is important to understand the relationship between human water use and climate extremes to develop more sustainable water management practices in the future," said the study's lead author Bridget Scanlon, a senior research scientist at the UT Bureau of Economic Geology, a research unit of the Jackson School of Geosciences. The study also highlights how surface water plays A map showing total water storage change in cubic an important role in replenishing groundwater, with kilometers for 14 major aquifers over 15 years based on these water resources helping dampen the impacts satellite data. A study led by The University of Texas at of irrigation. Austin used the data to examine how irrigation and climate influenced each aquifer’s water supply. Total water storage includes groundwater, soil water and For instance, groundwater pumping for irrigation in surface water.

But satellite data showed that the Mississippi Embayment didn't experience any long-term groundwater depletion despite the high levels of Researchers at The University of Texas at Austin pumping. Researchers attributed this to have created a balance sheet for water across the groundwater pumping capturing water from the United States—tracking total water storage in 14 of dense stream network in the humid Mississippi the country's major aquifers over 15 years.
