Insight into Western Stemmed Tradition cultural patterns based on analysis of Pit Feature 95 at the Cooper's Ferry Site (10IH73), Idaho

Creator:

McPherson, Gabrielle

Abstract:

Excavations at the Cooper’s Ferry site (10IH73) revealed a long record of repeated human occupation extending from the late Pleistocene into the early Holocene (~16,000-10,000 cal BP) and have yielded unique insights into the Western Stemmed Tradition (WST), which includes. Several studies have focused on WST pit features encountered at...

Preventing the Accumulation of Fine Sediments in Sand Dam Reservoirs: An Analytical Framework and Flume Experiments

Creator:

Ellingson, Joseph M.

Abstract:

Sand dams – low-head dams built in ephemeral streambeds that store water within saturated sediments – are a proven means to increase water supplies for rural communities in arid and semiarid regions. Water percolates into the reservoir-impounded sediments during wet season rains and can subsequently be extracted during the dry...

The Influence of Lithology on Stream Metabolism in Mountain Systems

Creator:

Cargill, Samantha K.

Abstract:

Physical disturbance in streams has important effects on the metabolic rates of gross primary production (GPP) and ecosystem respiration (ER). Underlying lithology can control sediment size, amount, and evolution in the stream, influencing substrate stability and its effect on benthic organisms. We assessed the patterns of disturbance and recovery of...

Investigating One-way Stream-aquifer Connectivity on Streamflow Predictions during Hydrologic Extremes in the National Water Model

Creator:

Jachens, Elizabeth R.

Abstract:

Surface water and groundwater are intimately connected by a two-way flux between the stream and the underlying aquifers; a complicated yet crucial relationship to represent in models. However, the National Water Model currently only considers a one-way flux, where groundwater can enter a stream but cannot return to the aquifer....

Geomorphic Evidence for Differential Rock Uplift Across the Southern Cascadia Forearc

Creator:

von Dassow, Wesley

Abstract:

The nature of upper plate deformation along the Cascadia subduction zone (CSZ) is poorly understood. Systematic covariation among topographic relief, geodetically determined uplift rates, decadal to millennial erosion rates, and the frequency of episodic tremor and slip (ETS) along the Cascadia forearc suggest a genetic association between forearc topography and...

Sediment transport modeling and implications for benthic primary producers in Oak Creek, OR

Creator:

Katz, Scott B.

Abstract:

The spatial and temporal variability of sediment transport processes in Oak Creek, OR was investigated and used to explore two study questions: 1) How do sediment transport processes influence benthic algal communities?, and 2) Can fluvial-hydraulic models make accurate predictions of bed load transport rates? Our study was conducted in...

Variation in the timing of coho salmon (Oncorhynchus kisutch) migration and spawning relative to river discharge and temperature

Creator:

LovellFord, Rachel M.

Abstract:

Coho salmon (Oncorhynchus kisutch) migration and spawning are unique components of the salmon life cycle because they require synchrony of behavior with other individuals as well as with acceptable fluvial conditions. As with other organisms that exhibit group mating behavior, it is likely that environmental cues trigger coho salmon movement...

Debris flows in glaciated catchments : a case study on Mount Rainier, Washington

Creator:

Legg, Nicholas T.

Abstract:

Debris flows, which occur in mountain settings worldwide, have been particularly damaging in the glaciated basins flanking the stratovolcanoes in the Cascade Range of the northwestern United States. This thesis contains two manuscripts that respectively investigate the (1) initiation processes of debris flows in these glaciated catchments, and (2) debris...

A comparative analysis of stream response to disturbance in the Pacific Northwest

Creator:

Hodgins-Carlson, Terry Anne

Abstract:

Published literature about six Pacific Northwest stream systems was contrasted to provide a regional perspective on channel response to disturbance. This investigation was prompted by a combination of recent environmental legislation, mounting social pressures to plan projects at a drainage basin scale, and the difficulty in defining and predicting the...

Masters Thesis
Dam removals and downstream bar-pool morphology

Creator:

Zunka, John Page Purnell

Abstract:

Bar-pool morphology in rivers can provide vital habitat to aquatic species, notably salmonids, which require gravel riffles to bury eggs and pools for hydraulic and cold-water refuge. In some cases, the erosion and subsequent deposition of coarse sediment downstream of a dam removal can modify habitat by inundating bar-pool structure,...
