Effects Of Stream Restoration And Storm Events On Stream-Groundwater Interactions, Margaret Zimmer

Earth & Environmental Sciences - Theses

The body of literature on stream-groundwater interactions is rapidly growing, but little is known about the effects of either storm events or in-stream restoration on the interactions between surface water and groundwater. The chapters of this thesis explore two of these questions at the same locality of interest: (1) subsurface geochemical dynamics across a riffle bedform in an unrestored stream during a storm event and subsurface geochemical, and (2) hyporheic exchange dynamics at baseflow conditions pre- and one year post- stream restoration.

The study site was a 30 m stretch of stream that underwent stream restoration through installation of a …
