Sediment production and delivery in Pistol River, Oregon and its effects on pool morphology

Creator:: Russell, Periann
Abstract:: Sediment production and delivery in Pacific Northwest coastal streams can have damaging effects on channel morphology and anadromous fish habitat. The research in Pistol River was designed to determine if a link exists between sediment delivery processes and degradation of fish habitat. Objectives of this basin-wide analysis were to: 1)...

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...

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...

Will we need to change the rules : assessing the implications of climate change for dam operations in Oregon's McKenzie River Basin

Creator:: Danner, Allison G.
Abstract:: Dams and reservoirs are important components of water resource management systems, but their operational sensitivity to streamflow variability may make them vulnerable to climate change. Climate change is likely to affect the magnitude and timing of streamflow, motivating the assessment of potential impacts on dams and reservoirs. Here I examine...

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...

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...

Hydrology and geomorphic evolution of basaltic landscapes, High Cascades, Oregon

Creator:: Jefferson, Anne (Anne Jarvis)
Abstract:: The basaltic landscapes of the Oregon High Cascades form a natural laboratory for examining how geologic setting and history influence groundwater flowpaths, streamflow sensitivity to climate, and landscape evolution. In the High Cascades, highly permeable young basaltic lavas form extensive aquifers. These aquifers are the dominant sources of summer streamflow...

Hydraulic predictors and seasonal distribution of Manayunkia speciosa density in the Klamath River, CA, with implications for ceratomyxosis, a disease of salmon and trout

Creator:: Jordan, Michelle S.
Abstract:: The freshwater polychaete Manayunkia speciosa was identified as an obligate host of the salmonid parasite Ceratomyxa shasta in 1997, prompting increased research on the small benthic invertebrate. Ceratomyxa shasta infection in fish can cause mortality, and presents a disease risk for both hatchery and wild salmon and trout. Ceratomyxa shasta...
