A climatography-based study of aerial reconnaissance probabilities for Oregon's Willamette Valley

Creator:: Spear, Timothy Bryant
Abstract:: The needs and markets for aerial photography have grown steadily with the increasing demands for improved resource management (Kodak, 1985, 2 & Simonett, 1983, 1). Aerial photography within the Willamette Valley could provide researchers and professionals with a broad range of data in disciplines such as agriculture, forestry, geology, and...

Changes in floodplain occupance Portland, Oregon 1957-1986

Creator:: Chaney, Richard Earl
Abstract:: Portland, Oregon Is in the northern end of the Willamette River Basin and Valley. The Willamette River caries the runoff discharge from approximately 12,000 square miles of basin area, and flows northward where it bisects the Portland metropolitan area and enters the confluence with the Columbia River. However, high discharge...

The influence of map complexity on interpolation accuracy.pdf

Creator:: Young, Brian K.
Abstract:: In this paper "map complexity" refers to the inherent intricacy of a mapped geographic pattern. Map complexity and sample size are two variables shown to influence the accuracy of interpolated dasymetric maps. An automated experiment was designed to investigate the precise relationship among map complexity, sample size, and the accuracy...

Water management in the North Deschutes unit irrigation district : geographic perspectives and remote sensing applications

Creator:: Nellis, M. Duane
Abstract:: The North Unit irrigation District of Central Oregon, a water project developed under the guidelines of the Bureau of Reclamation, is characterized by limited water and the need for efficient utilization and control of the irrigation system. To manage the limited water resource, irrigators need a timely and economical method...

Soils of the Oregon coastal fog belt in relation to the proposed "Andisol" order

Creator:: Badayos, Rodrigo Briones
Abstract:: A study was conducted to evaluate the properties of soils in the fog belt area of the Oregon Coast Range. Soils in the study were chosen to include only those belonging to Andepts or to andic subgroups. Samples were collected from eleven sites that were formed mostly from colluvial deposits...

Lower Salmon River Cultural Resource Management Plan

Creator:: Sisson, David A.
Abstract:: Cultural resource inventories have identified,205 individual sites on public land along the Lower Salmon River, Idaho. These sites represent a rich and diverse record of the human occupation and utilization of the river canyon during the past 10,000 years. Each of these 205 sites contains its own unique record of...

Riparian vegetation recovery in the blast and airfall tephra zones of Mount St. Helens, Washington

Creator:: Kiilsgaard, Christen W.
Abstract:: Riparian vegetation patterns within the blast, downstream of blast, and airfall tephra zones of Mount St. Helens are related to initial and secondary volcanic disturbance, post-eruption fluvial landforms, channel geometry, and streamflow characteristics. Vegetation patterns were determined from species presence observed on transects across landforms developed along the streams. Distinct...

Biomass and community structure of sporocarps formed by hypogeous ectomycorrhizal fungi within selected forest habitats of the H. J. Andrews Experimental Forest, Oregon

Creator:: Luoma, Daniel L.
Abstract:: This study characterizes the production of hypogeous sporocarps (broadly referred to as truffles) by ectomycorrhizal fungi within Douglas-fir dominated forests that are considered typical of those found on the west slopes of the central Cascade mountains in Oregon. Three aspects of sporocarp production are addressed: 1) the distribution of total...

Contextual systems description of an Oregon coastal watershed

Creator:: Goetze, Brigitte
Abstract:: Many resource management controversies indicate disagreement about the possible intended and unintended effects of management actions on ecosystems. Researchers have documented a variety of negative effects on specific ecosystems, e. g. the degradation of salmonid habitat due to mass wasting (Hagans et al. 1986). While the effects of some management...
