Vegetation ecology of Fraxinus latifolia communities in William L. Finley National Wildlife Refuge, Oregon

Creator:: Heinitz, Eric Fajen
Abstract:: Composition and structure of Oregon ash (Fraxinus latifolia) woodlands in the William L. Finley National Wildlife Refuge, Oregon are described. Twenty stands dominated by Fraxinus latifolia were sampled with 500 m2 circular macroplots in which floristic microplot data were collected for plant community synthesis. Plant communities were identified by computer-assisted...

A georeferenced digital image analysis of micro-topographic patterns within the Willamette Floodplain Research Natural Area, W. L. Finley National Wildlife Refuge

Creator:: Anderson, Karen L.
Abstract:: The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...

The Willamette River greenway : environmental and attitudinal considerations

Creator:: Honey, William D.
Abstract:: The Willamette River Basin, Oregon, viewed in terms of a cultural-ecological system, has been subject to three phases of cultural development: hunting and gathering, agrarian, and industrial-urban. Each population base has employed a technology to exploit the environment to the extent that its patterns of culture would allow. This technology...

Post-Aggregate Aggregation : A Geographic Evaluation of Enhancement Reclamation at Aggregate Mines in the Western United States

Creator:: Morrison, Elizabeth A.
Abstract:: The aggregate industry is responsible for the extraction and production of crushed stone, sand, and gravel— the literal building blocks of our society. Across the U.S. there are tens of thousands of quarries and sand and gravel pits, the majority of which are left abandoned or with minimal reclamation efforts....

Sequent occupance study in Fauquier County, Virginia

Creator:: Finkl, Charles William
Abstract:: The problem of this thesis is the existence of an anomalous manorial landscape in northern Fauquier County, Virginia. The county is about 45 miles southwest of Washington, D. C. The thesis seeks to develop a hypothesis to explain the existence of this landscape so different from surrounding areas in a...

Irrigated agriculture, energy, and endangered species in the Upper Klamath Basin : Evaluating trade-offs and interconnections

Creator:: Boehlert, Brent B.
Abstract:: In 2001, an extreme drought tightened water supply in the Upper Klamath Basin (basin) while earlier increases in Endangered Species Act (ESA) water requirements for basin fish species that same year elevated demands. The Bureau of Reclamation (Reclamation), which manages irrigation water in parts of the basin located near the...

An Investigation of Photographic Band-Ratioing

Creator:: Fisher, Scott William
Abstract:: A photographic band-ratioing technique was investigated. The data source consisted of 70 mm Landsat Multispectral Scanner (MSS) negatives. The process would require combining registered positive and negative transparencies to achieve a ratio modulation in the resulting print. This would also require compensation for atmospheric effects on the original negatives by...

An investigation into modeling snow cover elements at Crater Lake National Park and surrounding environs as an improved "ground truth" method for satellite snow observations

Creator:: Hamilton, William L.
Abstract:: Streamflow forecasts are essential to the optimal operation of hydroelectric and irrigation reservoirs in the Pacific Northwest. Satellite snow cover observations would aid in these streamflow forecasts by providing snow cover data at regular time intervals. Unfortunately, satellite capability to remotely sense mountain snow cover conditions is indeterminate due to...

Factors affecting solar access in the Portland-Vancouver Metropolitan Area

Creator:: Molnar, William
Abstract:: This study examines the relationships among variables influencing solar access in the Portland-Vancouver Metropolitan Area. The analysis is based on a random sample of approximately 400 single-family homes in 21 local jurisdictions outside the city limits of Portland. Relationships between percentage of available sunlight and selected variables were examined by...

A technique for predicting the urban structure of a region

Creator:: Warwick, William Michael
Abstract:: The two classic theories of the distribution of cities in an urban system are the rank size rule and central place theory. The rank size relationships, as incorporated into G. K. Zipf's Principle of Least Effort, is seen as the result of a balancing of the opposing forces of urban...
