Increased water temperatures and thermal loading due to anthropogenic inputs has
been shown to negatively impact the lifecycles of aquatic organisms in riverine
systems (Poole and Berman 2001; Hannah, Malcolm et al. 2004; Quinn, Gagne et al.
2004). The studies enclosed in this thesis evaluate and quantify the heat fluxes...

Diking and channelizing in the Toppenish Creek basin, associated with irrigated agricultural development, has altered its natural ecosystem function and hydraulic processes. We seek to answer two research questions: if surface waters are diverted for aquifer recharge in the winter, will this water be available for ecosystem function in the...
Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...
Understanding the transport and retention of radionuclides in the environment is important for protecting freshwater supplies and minimizing impact to biologic systems. Technetium-99 (Tc⁹⁹) is a radionuclide of interest due to its long half-life (2.13 x 10⁵ years) and toxicity. In the form of pertechnetate (TcO₄⁻), Tc is expected to...
The thermal regime of rivers plays a key role in aquatic ecosystem health. In the Willamette River, OR, the present day main channel temperature is often too warm for cold water fishes during the late spring, summer, and early fall. At these times, cold water fishes tend to be concentrated...
