dc.description.abstractObserving microseismic waves excited by turbulent flow is an emerging way to document river dynamics during extreme flood events. This thesis records fluvial-seismic observations in two contrasting systems at different scales. Two single-seismometer particle motion methods are introduced to characterize the seismic signal produced by rivers. In the large-scale system, the Oroville Dam spillway is observed when it is a simple rectangular channel and when it is damaged by erosion. The small-scale system is along the cobble-bed Northwest Branch of the Anacostia River. Particle motion analyses and the scaling between seismic power and discharge are suitable to characterize flow turbulence at the large-scale system. In the small-scale system, particle motion methods are found to be unsuitable and the scaling of seismic power is unable to resolve observed variability in flow dynamics within the study reach. This work suggests that methods of fluvial seismology are best suited to large-scale systems.en_US
