Historical Change and the Hydrogeomorphic Context of Present-day Floodplain Forests in the Willamette Valley, Oregon

Creator:: Bervid, Heather D.
Abstract:: Floodplain forests play many important roles in the fluvial processes and environments of large alluvial rivers, including acting as geomorphological influences and habitat for native fish during high flows. Many large, gravel-bed river systems have undergone substantial change in recent centuries, resulting in loss of forested area to agriculture, reduction...

An evaluation of the potential for land use management as an air pollution control measure within the Willamette Valley

Creator:: Vinton, Larry Richard
Abstract:: The rapid population growth and related economic growth of the Willamette Valley has resulted in a significant reduction in air quality over the past several decades. Within the Willamette Valley air ventilation is very poor and therefore the airpo1lutton potential is one of the highest in the United States. There...

A geographic application project utilizing location-allocation computer programs to determine canning facility locations in the Willamette Valley

Creator:: Maddocks, Nicholas Anthony
Abstract:: A Willamette Valley farm cooperative was interested in evaluating locations for their canning facilities based on the criterion of minimizing aggregate distance to their contract farms. This location problem presented an excellent opportunity for a geographic application project as it was characterized by one, a spatial distribution of farms and...

Small mammal assemblages in natural and restored wet prairies: an evaluation of habitat in Oregon's Willamette Valley

Creator:: Slane, Lori B.
Abstract:: This study was conducted to explore differences in diversity and abundance of small mammal populations in natural and restored wet prairies in Oregon's Willamette Valley. Mammals were live-trapped in eight Willamette Valley wet prairies (four natural remnants and four restorations) during the summer of 2000; population abundance estimates for each...

Geology, flooding & human activities : establishing a hierarchy of influence for controls on historic channel change, Willamette River, Oregon

Creator:: Wallick, Jennifer Rose
Abstract:: Channel evolution and influences of changing floodplain characteristics, heterogenous bank materials, and altered flow regimes were examined along the Willamette River, a large alluvial river in northwestern Oregon. The Willamette River is composed of a series of geomorphically diverse reaches, which have each evolved uniquely in the century following Euro-American...

Geochemical characteristics of iron-manganese nodules in seasonally-saturated soils of the Willamette Valley, Oregon

Creator:: Seter, Lisa M.
Abstract:: This study was initiated to characterize the distribution of Fe-Mn nodules and to elucidate trends of Fe, Mn, and P relative to the intensity of the annual cycles of reduction and oxidation. Nodules were enriched in Fe, Mn, and P relative to the soil matrix making them an integral part...

Riparian cover changes associated with flow regulation and bank stabilization along the Upper Willamette River in Oregon between 1939 and 1996

Creator:: Gutowsky, Sharon L.
Abstract:: This study investigates riparian cover change between 1939 and 1996 utilizing aerial photography, bank conditions and stream gauge data. Three sites under 1.0 km2, along a 10- km reach north of Harrisburg, Oregon, were evaluated. The cover classification scheme included 18 classes composed of 3 canopy densities and 8 structural...

Meander scars : reflections on healing a river

Creator:: Metzger, Abby P.
Abstract:: As Europeans settled the Willamette Valley in the 1800s, they began to simplify Oregon's largest river contained wholly within state boarders—the Willamette. The river lost miles of channels from dikes, dams, and development. Some channels vanished under concrete. Others became meander scars, or shallow, dry depression in the land where...

Climate warming effects on the life cycle of the parasite Ceratomyxa shasta in salmon of the Pacific Northwest

Creator:: Chiaramonte, Luciano V.
Abstract:: Aquatic ecosystems continue to be increasingly affected by climate warming. For salmonids in the Pacific Northwest of North America, increasing temperatures pose tighter thermal constraints on their habitat use as well as aspects of their individual performance, such as disease resistance. This thesis examines the effect of temperature on the...
