Multi-Scaled Approaches For Protecting Montana's Watersheds And Water Resources, Elizabeth Yoder Apr 2017

Multi-Scaled Approaches For Protecting Montana's Watersheds And Water Resources, Elizabeth Yoder

Graduate Student Portfolios, Professional Papers, and Capstone Projects

The central theme carried among my four portfolio pieces is: using scientific and governmental approaches to conserve watershed health. For the purposes of this portfolio, I define watershed health as a very general term that describes the state of water quantity and quality that is available for human and ecosystem needs in a watershed. I see each of my portfolio pieces focusing on a different scale and method (i.e., science or government, including different levels of government, local, state and federal) for conserving watershed health. My first portfolio piece reviews water quality degradation caused by pharmaceuticals and personal care products …


Stream Restoration Effects On Hydraulic Exchange, Storage And Alluvial Aquifer Discharge, Christine M. Brissette Jan 2017

Stream Restoration Effects On Hydraulic Exchange, Storage And Alluvial Aquifer Discharge, Christine M. Brissette

Graduate Student Theses, Dissertations, & Professional Papers

Stream restoration is increasingly being considered as a climate change mitigation tool, altering the storage and exchange capacities of streams and their adjacent alluvial aquifers. While previous research has shown that added geomorphic complexity and increased width-to-depth ratios can enhance hydraulic exchange and alluvial aquifer storage, few studies have used field data to link these changes in form to baseflow generation. In this paper, we quantify the effect of stream restoration on nested scales of hydraulic exchange and temporal patterns of alluvial aquifer recharge and discharge. Our work compares a restored and degraded reach on Ninemile Creek, Montana following extensive …
