Woody riparian species patterns along northeast Oregon mountainous streams and the relationship to riparian capability

Creator:: Yancey, Jennifer M.
Abstract:: Woody riparian vegetation is an essential component of riparian ecosystems, responsible in part for the maintenance of functional ecological processes. The plant community composition and distribution provide an indication of the underlying mosaic of environmental attributes and processes. Restoration and management of riparian communities have been hindered by the lack...

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...

Wave propagation processes at the mouth of the Columbia River

Creator:: Andes, Lisa (Lisa Christine)
Abstract:: The mouth of the Columbia River (MCR) has a longstanding reputation of hazardous navigational conditions. This reputation has been developing since the first ship, the Columbia, traversed through the inlet in 1792. The hazardous conditions are related to the large waves and strong tidal currents that are common in the...

Vertical distribution of radioactivity in the Columbia River estuary

Creator:: Hanson, Peter James
Abstract:: In situ salinity, turbidity and temperature were measured at discrete depths and water samples for radioanalysis were simultaneously collected in the Columbia River Estuary using a specially designed instrument package. Particulate radioactivity was concentrated by filtration and the dissolved radioactivity by evaporation or ferric oxide bulk precipitation. Radioanalysis was by...

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...

Utilization of the Columbia River Estuary by American shad, Alosa sapidissima (Wilson)

Creator:: Hammann, Mark Gregory
Abstract:: The migrations, distribution, and feeding of American shad, Alosa sapidissima (Wilson), were studied from February 1980 through January 1981 in the Columbia River Estuary, an important rearing zone for young-of-the-year shad. Sampling was performed with purse seine, beach seine, and otter trawl. Adult shad and large numbers of juveniles from...

Urban residents and non-point source pollution : an examination of practices, influences, and values in the Tualatin watershed

Creator:: Nielson, Lisa M.
Abstract:: In July of 2001, the Environmental Protection Agency (EPA) activated the Total Maximum Daily Load (TMDLs) provisions of the Clean Water Act. As the first river in Oregon to implement TMDL regulations, people and agencies in the Tualatin basin face many challenges. Non-point source pollution affects water quality in the...

Tsunami propagation in large rivers : idealized cases and the Columbia River Estuary

Creator:: Kalmbacher, Kirk D.
Abstract:: The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a...

The willingness of Central Oregon irrigators to donate water rights to augment Deschutes River flow

Creator:: Barkley, David, 1972-
Abstract:: This study used contingent valuation techniques to estimate the willingness of central Oregon Irrigators to donate a portion of their water rights to increase Deschutes River flow. This study was different from previous contingent valuation studies in that it used water rights as the payment vehicles instead of dollars -...
