Thorleifson, H., and M.O. Saar, Groundwater sustainability: methods for analysis, mapping, monitoring, and management of regional systems, symposium at the GSA North-Central meeting in Minneapolis, MN, May 19-20, 2005.
Abstract:
Regional large-scale groundwater flow rates and patterns are difficult to determine using local pump tests of permeability and/or artificial tracers as permeability is often highly heterogeneous and long-range flow rates may be too small to monitor on reasonable time-scales. However, it is often this large-scale groundwater flow field that is of interest for studies investigating long-term water resources, regional groundwater contamination, subsurface storage of (radioactive) waste, or geothermal energy resources. To study such problems, natural groundwater flow "tracers" may be employed which may include major elements, stable and unstable isotopes, noble gases, heat, and possibly even fluid induced microseismicity. We invite contributions that present quantitative results derived from analytical and numerical modeling studies, laboratory experiments, and/or field studies of groundwater flow coupled with mass and/or energy transfer to infer groundwater flow rates and patterns on a regional scale.
