Graduate students Marsha Allen and Sarah McKnight are representing U-Mass Geosciences this week at the annual meeting of the International Association of Hydrogeologists in Malaga, Spain.  Marsha will be presenting her research on groundwater storage assessment and flow path identification in large-scale fractured bedrock aquifer systems, with Sarah presenting her research on hydrologic and stratigraphic impacts to density-driven flow along brine-to-freshwater interfaces in arid basins.
