50 YEARS OF STREAM GROUNDWATER EXCHANGE SCIENCE, HAVE WE PROVIDED MANAGERS WITH USEFUL TOOLS OR UNUSABLE SCIENCE? IS THERE HOPE? (Invited Presentation)


WOESSNER, William, Geosciences, Univ of Montana, 32 Campus Drive #1296, Missoula, MT 59812, william.woessner@umontana.edu

The ecologists recognized in the 1930's that some stream sourced invertebrate fauna were present in the gravels associated with adjacent river systems; by 1959 the term hyporheic was coined. At the same time groundwater text books recognized the link between surface water and groundwater by referring to streams generally as effluent (receiving groundwater discharge) or influent ( recharging groundwater). In addition, Todd's(1959) text illustrated stream groundwater exchanges that today would be referred to a flow-though and parallel flow. So after 50 years of enhancing our understanding of the exchange process is this science being used to benefit society? Some state's legal systems don't recognize a hydrologic continuum. Calls are being made to include hyporheic restoration in stream restoration efforts. Can we answer the questions: When is a groundwater system disconnected from surface water?; How much restored stream groundwater exchange is too much?
