GSA 2017 ANNUAL MEETING & EXPOSITION
T15. Monitoring the Complex Nature of Water Balances
and Solute Transport at the Groundwater–Surface
Water Interface
Cosponsors: GSA Hydrogeology Division; GSA Environmental
and Engineering Geology Division
Disciplines: Hydrogeology, Environmental Geoscience,
Geochemistry
Advocates: Mackenzie Cremeans; J.F. Devlin
This session addresses advances in the study of groundwater–
surface water interactions covering modeling, field instrumenta-
tion, and assessment of water and solute fluxes across the
interface. Environments considered will include streams, lakes,
wetlands, and irrigation drainage.
T16. Novel Approaches to Mine Remediation:
Addressing the Legacy of Hardrock Mining
through Innovative and Practical Methods
Cosponsors: GSA Hydrogeology Division; GSA Environmental
and Engineering Geology Division
Disciplines: Hydrogeology, Environmental Geoscience,
Engineering Geology
Advocates: Kato T. Dee; William J. Walker
The legacy of hardrock mining has resulted in tens of thousands
of abandoned mine sites in the Western United States. This ses-
sion explores innovative and practical remediation approaches of
abandoned hardrock mines.
T17. Polar and Alpine Changes
Cosponsors: GSA Hydrogeology Division; GSA Geobiology &
Geomicrobiology Division
Disciplines: Hydrogeology, Environmental Geoscience,
Geomorphology
Advocate: W. Berry Lyons
Polar and high alpine environments are undergoing rapid
changes including cryosphere loss, with important geomorpho-
logical, hydrological, biogeochemical, and ecological conse-
quences. This interdisciplinary session will explore these changes
in both the Arctic and Antarctic.
T18. Remote Sensing Applications in Hydrology
and Geology
Cosponsors: GSA Hydrogeology Division; GSA Geoinformatics
Division; GSA Geophysics Division; GSA Geology and Society
Division; GSA Environmental and Engineering Geology Division
Disciplines: Hydrogeology, Geophysics/Geodynamics,
Geoinformatics
Advocates: R.H. Becker; Adam M. Milewski; Rachel R. Rotz
Recent innovations and sensors have broadened the capabilities
of remote sensing, from UAV to satellite. A range of geologic,
geomorphic, and hydrologic applications can be addressed. This
session welcomes applications of the sensors to geologic questions.
20 22–25 October 2017 • Seattle, Washington, USA
T19. Springs: Providing Insights on Critical
Groundwater Quality and Quantity Issues
Cosponsors: GSA Hydrogeology Division; GSA Environmental
and Engineering Geology Division; GSA Geobiology &
Geomicrobiology Division; GSA Karst Division
Disciplines: Hydrogeology, Karst, Environmental Geoscience
Advocates: Brian Katz; Sue Swanson; James L. Berglund
This session will highlight research studies on springs that
cover a range of topics, including water quality, geochemical and
microbiological tracers for elucidating sources of anthropogenic
impacts, water quantity, ecology, springs restoration, and
climate change.
T20. The Critical Zone As Heterogeneous Media: Implications
for Physical, Chemical, and Biological Processes
Cosponsors: GSA Hydrogeology Division; GSA Soils and Soil
Processes Interdisciplinary Interest Group; GSA Geobiology
& Geomicrobiology Division; GSA Karst Division
Disciplines: Hydrogeology, Soils
Advocates: Wendy M. Robertson; Nicole West; Zsuzsanna
Balogh-Brunstad; Michael H. Young
We encourage contributions that characterize heterogeneities
in the Critical Zone and their connections to hydrologic and bio-
geochemical processes at a range of spatial and temporal scales.
T21. Using Natural and Anthropogenic Tracers to
Determine Recharge and Residence Times within Arid
to Semi-Arid Inter-Montane Aquifer Systems
Cosponsor: GSA Hydrogeology Division
Disciplines: Hydrogeology, Environmental Geoscience, Geology
and Health
Advocates: P.S.K. Knappett; D. Kirk Nordstrom; Jurgen
Mahlknecht; Hongbin Zhan
Inter-montane aquifer systems in arid regions are experiencing
increased groundwater abstraction. We encourage abstracts on the
hydrologic cycle in these basins to quantify groundwater recharge,
groundwater quality, and discharge processes, especially with
natural/anthropogenic tracers.
T22. Water Resources and Management in Coastal
and Inland Aquifers—Emphasis on Small Island
Developing States of the Caribbean
Cosponsors: GSA Hydrogeology Division; GSA International/
International Interdisciplinary Interest Group; GSA Geology
and Health Division; GSA Geology and Society Division; GSA
Environmental and Engineering Geology Division
Disciplines: Hydrogeology, Environmental Geoscience, Geology
and Health
Advocates: Arpita Mandal; Debbie Ann Gordon Smith; Saugata
Datta; Katherine K. Ellins
The session seeks presentations on current research focusing on
Caribbean water resources (but not restrictive to Caribbean only,
