Water Quality Responses To A Semi-Arid Beaver Meadow In Boise, Idaho, Luise Bayer Winslow
Water Quality Responses To A Semi-Arid Beaver Meadow In Boise, Idaho, Luise Bayer Winslow
Boise State University Theses and Dissertations
Beavers have been instrumental in shaping the North American riverine landscape. However, land use change and beaver trapping have caused large decreases in beaver populations, resulting in fundamental changes to river morphology, hydrology, and biogeochemical function. Effective river restoration and remediation of arid western rivers relies on a comprehensive interpretation of how beaver activity influences water quantity and quality. In this study, I compared two stream reaches with and without beaver dams in a semi-arid watershed, to quantify the effects of beaver activity on hydrology and biogeochemistry. Within each reach, I combined dilution gauging and stream tracer experiments to determine …

Estimating Floodplain Storage And Prioritizing Floodplain Reconnection In The Northern Lake Champlain Basin In Vermont, Stephanie Drago
Graduate College Dissertations and Theses
Floodplains play a major role in maintaining the health and sustainability of riverine systems, but human interventions have reduced the connectivity between stream channels and floodplains. Geomorphic assessments of streams and rivers in Vermont (USA) show they have been significantly altered within the past two centuries due to straightening, berming, and armoring channels to accommodate development, agriculture, roads, and rail lines. These alterations in river-floodplain connectivity have decreased floodplain functioning, specifically their capacity to store water during flood events. Currently, there is a lack of knowledge concerning the amount of floodwater, sediment, and nutrient retention provided by Vermont’s floodplains. This …
