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...

Influences of landslides, floods and land use on channel changes of the upper Middle Fork Willamette River, Oregon 1936-1980

Creator:: Lyons, Joseph Kevin
Abstract:: Time trends in flow and channel characteristics were evaluated for the Middle Fork Willamette (MFW) River, which drains a 668 km2 forested watershed in the Cascade Mountains of western Oregon. Timber production is the primary land use in the watershed. Analysis of precipitation and peak flow data from 1959 to...

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...

An evaluation of the oxygen resources in the lower Willamette River during a critical low flow period

Creator:: Kari, Earl Nyhus
Abstract:: The lower Willamette River, located between river mile 4.0 and 26.5, is the most seriously polluted section of the Willamette River Basin. Low dissolved oxygen concentrations of 2.0 to 3.0 mg/1 are observed annually in this section of the river due to the pollutional loads discharged into it. Waste discharges...

Peavy Arboretum : an archaeological and historical investigation of a Willamette Valley landscape

Creator:: Hylton, Lindon B.
Abstract:: This thesis documents a period of ecological and cultural change on a Willamette Valley, Oregon landscape. In particular, this study examines the Peavy Arboretum area and the cultural changes that accompanied the transformation of the landscape from an oak savannah in the mid-nineteenth century to a dense Douglas-fir forest in...
