This thesis was to develop a bone artifact typology for the Oregon coast. This typology was used to test the hypothesis that different geographical regions of the Oregon coast would have different artifact assemblages associated with them. These regions, identified by geologist from landform changes, have been defined as: region...
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 wetlands are distinguished from other lands of the Mid-Willamette Valley by excessive soil moisture. The wetlands, as defined for this study, consist of 20 soil series (in 22 soil mapping units) which are classified by the Soil Conservation Service as having excessive wetness as the major factor limiting their...
The Chelan Valley is one of several valleys located on the eastern slope of the Cascade Mountains contributing to the leadership of Washington in apple production. Since the nature of the activity in the Chelan Valley is typical of all these producing areas,it was selected as a case study of...
Re searchers have long tried to correlate weather factors with plant disease occurrences. However, inconclusive results have usually been obtained because most plant diseases have biologic as well as climatic optimums.
In this study, thirty weather variables were correlated, by the stepwise regression method in a computer, to the amount...
The siting of a new industrial plant generally results
from the favorable match of the needs of an industrial
firm arid the assets of a community. Citizens of
Oregon have taken a very active role in planning and decision
making at the local level due to legislation in
the past...
Agricultural field burning in Oregon's Willamette Valley
has been an accepted farming practice for sanitizing fields and removing
stubble and residues left on fields after harvest since the
early 1940s. Unfortunately, the smoke and debris created by the
burning in combination with other pollutants have been causing health
and environmental...
The need to control irreversible conversions of
prime agricultural lands to urban land uses has come to light
in recent years. Resulting policy statements by the State of
Oregon and federal agencies have added support to this
premise. Nevertheless, inefficient conversions of agricultural
to idle lands in response to urban...
Rivers are becoming increasingly popular recreation
resources as land and water use competition intensifies. The
first river basin board in Nova Scotia was formed to manage
the Shubenacadie-Stewiake Rivers under multiple use objectives.
The board required an estimation of the recreation resources
of the Stewiake River and after a review...
The value per-acre and annual amortization of
rural land varies dynamically by parcel size. There are
several adjustment factors or independent variables
spatial, productive and development potential which affect
the market value of all rural land. The evaluation of
these must be accomplished by parcel size to be realistically
equated....
