Patterns of hillslope and channel recovery following disturbances in steep, forested basins

Creator:: Madej, Mary Ann
Abstract:: Geomorphic response to watershed disturbances commonly results in alterations of landforms. Subsequent geomorphic recovery is dependent on the ability of flows to entrain, transport, and organize inorganic and organic material on hillslopes and in channels. This research analyzed changes in sediment production, channel structure, and channel organization following disturbances in...

Patterns and processes of sediment transport following sediment-filled dam removal in gravel bed rivers

Creator:: Stewart, Gregory B.
Abstract:: Dam removal is increasingly viewed as a river restoration tool because dams affect so many aspects of river hydrology, geomorphology, and ecology; but removal also has impacts. When a dam is removed, sediment accumulated over a dam’s lifetime may be transported downstream; and the timing, fate and consequences of this...

Spatial and temporal trends in bed material and channel morphology below a hydroelectric dam complex, Deschutes River, Oregon

Creator:: McClure, Ellen M.
Abstract:: River regulation imposes changes in the supply of sediment and the frequency of competent flows. As a result, impounded rivers often exhibit downstream changes in channel processes, particle size, and morphology. The magnitude of change in competent flow frequency and sediment load together can be used to predict the pattern...

Agonistic behavior in three species of Microtus (M. canicaudus, M. oregoni, and M. townsendii)

Creator:: Weil, James Wayne
Abstract:: Agonistic behavior among three species of Microtus live-trapped near Corvallis, Oregon was recorded in order to interpret habitat segregation by the species in areas of syrnpatry. The method used to measure agonistic interaction was similar to that of Colvin (1970). Agonistic behavior was recorded under red light in a neutral...

Distributions and fishery associations of immature short-tailed albatrosses (Phoebastria albatrus) in the North Pacific

Creator:: O'Connor, Amelia J.
Abstract:: Short-tailed albatrosses (Phoebastria albatrus, hereafter "STAL") migrate throughout the North Pacific, overlapping with multiple large scale fisheries. In the Bering Sea, documented bycatch of this species is a focal conservation concern, due to the fact that this species is listed as "endangered" under the U.S. Endangered Species Act. We conducted...

Influence of hyporheic flow and geomorphology on temperature of a large, gravel-bed river, Clackamas River, Oregon, USA

Creator:: Burkholder, Barbara K.
Abstract:: The hyporheic zone influences the thermal regime of rivers, buffering temperature by storing and releasing heat over a range of timescales. We examined the relationship between hyporheic exchange and temperature along a 24-km reach of the lower Clackamas River, a large gravel-bed river in northwestern Oregon (median discharge = 75.7...

Contrasting geomorphic responses to climatic, anthropogenic, and fluvial change across modern to millennial time scales, Clackamas River, Oregon

Creator:: Wampler, Peter J.
Abstract:: Geomorphic change along the lower Clackamas River is occurring at a millennial scale due to climate change; a decadal scale as a result River Mill Dam operation; and at an annual scale since 1996 due to a meander cutoff. Channel response to these three mechanisms is incision. Holocene strath terraces,...

An interindustry analysis of the importance of grazing on federal lands to the economy of Grant County, Oregon

Creator:: Bromley, Daniel W., 1940-
Abstract:: Use of federal lands for commercial and recreational activities contributes significantly to the economic stability of many rural areas. Recent increases in demand for recreational use have created conflicts between uses and among users. Some are questioning the use of public land for private gain. The seemingly low grazing fees...

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...
