Impacts Of Beaver Dams On Mountain Stream Discharge And Water Temperature, Timothy R. Clark

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Beaver dam complexes have been shown to affect the hydrologic processes controlling river systems. These processes include surface and groundwater exchanges, water chemistry and temperature variations, and river discharge magnitudes. Majerova et al. (2015) explored the effects of beaver dams on surface and groundwater exchanges and water temperature by evaluating three years of water discharge and temperature data recorded at multiple locations within a small stream in northern Utah. They found that beaver dams increase the water surface elevation and force water into the floodplain resulting in increased inundation and groundwater recharge. They additionally found that beaver dams increase residence …

The Effect Of Water Temperature On In-Stream Sediment Concentration And Transport Rate, Jennie Tyrrell

Dissertations, Master's Theses and Master's Reports

Global climate change may result in rising temperatures. As a result, ecological health and the human use of rivers may be impacted. The hydrologic cycle, watershed hydrology, and in-stream hydraulics are dynamic systems, influenced by human activities, natural events, and climate. Although known drivers like precipitation and stream velocity govern sediment processes, the effect of water temperature on sediment transport remains unclear. In-stream sediment movement could lead to blocked harbors, flooding, and degradation of vulnerable fish habitat. To better understand how fluctuations in water temperature affect sediment dynamics, six transport models were analyzed on the Niobrara River, with water temperatures …
