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...

Development of a GIS for the Marys River Watershed for fish and wildlife analysis

Creator:: Callahan, Brady
Abstract:: GIS technology has reached a point where it can be utilized by nonprofessionals in a desktop environment. This paper reviews the implementation of a pilot project for developing a localized-natural resource GIS. The resulting GIS was custom designed to answer questions posed by fish and wildlife biologists who need to...

Geographic variations in water quality and recreational use along the upper Wallowa River and selected tributaries

Creator:: McDowell, Theodore R.
Abstract:: Physical, chemical and bacterial water quality parameters of the upper Wallowa River were sampled periodically between July 2, 1978 and June 9, 1979 at nine stream and lake sampling sites. Water upstream from Wallowa Lake was typified by low nutrient concentrations ( generally below detectable limits except for nitrates), low....

Riparian canopy and channel response to hillslope disturbance in Elk River Basin, southwest Oregon

Creator:: Ryan-Burkett, Sandra E.
Abstract:: Elk River is a sixth order stream, draining a 200 square kilometer basin in the Klainath Mountain province of southwestern Oregon. Timber harvesting began in the basin during the 1950's, with peak removal of wood occurring in the mid to late 1960's. This activity lead to an increase in the...

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...

Side looking airborne radar mapping of wave refraction patterns at the mouth of the Columbia River

Creator:: Bell, James W.
Abstract:: The ocean wave conditions at the mouth of the Columbia River have long proven a hazard to ship navigation. Over 62 major shipwrecks have occurred at, or in the vicinity of the river entrance. The wave pattern is extremely complex, varying seasonally with prevailing winds and river discharge, as well...

Spatial and temporal patterns of windthrow in the Bull Run Watershed, Oregon

Creator:: Sinton, Diana Stuart
Abstract:: Throughout the 20th century, windthrow has affected forests in the Bull Run watershed, a 26,500 ha basin that is the principal water source for the city of Portland, Oregon. Windthrow from storms in 1973 and 1983 was mapped into a geographic information system (GIS) and compared to a 1931 windthrow...

Historical alterations to the Columbia River Gorge as a result of transportation infrastructure, 1850-1900

Creator:: Daniel, Isaac B.
Abstract:: Featuring high waterfalls and forested cliffs, and displaying a remarkable transition between the Pacific and Interior west, the Columbia River Gorge reveals the grandeur of western landscapes. Yet the landscape that one sees today is an amalgamation of the Gorge's natural setting and its unique human history. Historical research on...
