Characterizing Groundwater Recharge And Streamflow Using Stable Isotopes Of Oxygen And Hydrogen, Chanse M. Ford

Potential changes to climate and precipitation patterns from anthropogenic influences like global climate change could have an impact on Michigan’s groundwater resources. Indirectly this could have an effect on Michigan’s surface waters as well, since groundwater and surface waters are intimately linked to form one system.
This investigation utilized stable isotopes of oxygen and hydrogen found in precipitation, groundwater and surface waters to better understand the contribution of different types of precipitation to recharge of a shallow aquifer in Manistee National Forest, MI. The study also examines the contribution of this shallow groundwater to streamflow in the nearby White River. …

Masters Theses
Focused groundwater discharge in endorheic basins provides opportunities to investigate mechanisms for closing hydrologic budgets in arid regions. The Salar de Atacama (SdA), a closed basin in northern Chile, has accumulated over 1800 km3 of halite and a lithium-rich brine since the late Miocene primarily through evapotranspiration of groundwater. The hydrologic balance of SdA and sources of water and solutes required to explain this deposit are not well constrained. An adapted chloride mass balance method drawing on a database of over 200 water sample sites is applied to a remotely-sensed precipitation dataset to estimate spatially-distributed modern groundwater recharge.
