Terrain sensitivity of Oregon coastal sand areas

Creator:: Starr, Richard Merritt
Abstract:: Based on a pilot study completed near Heceta Beach, Oregon, guidelines have been proposed for the development of Oregon coastal sand areas. The guidelines, in the form of performance standards are designed with respect to the variability of coastal sand areas. Landscape units and vegetation associations were grouped to reflect...

Relationships between vegetation and terrain variables in southeastern Arizona

Creator:: Mouat, David A.
Abstract:: A study to determine the relationship between plant species and eight terrain variables and between thirty-one vegetation types and the terrain variables was conducted in a 4, 000 square mile area south and east of Tucson, Arizona. The eight terrain variables included elevation, parent material, macrorelief, landform type, drainage density,...

An inventory of Oregon county land use maps with recommendations for future standardization

Creator:: Batch, Donna Jeanne
Abstract:: An inventory of existing land use maps developed by Oregon county planning departments has been made through use of questionnaires and interviews. The degree of consistency has been examined with regard to the types of base maps, scales, projections, base information, and classification schemes employed. Recommendations have been made for...

The oyster industry in Oregon

Creator:: Stream, Roberta Ann
Abstract:: Aquaculture of oysters has never obtained the economic importance in Oregon as it has in other coastal states. There are at present seven commercial culturists in Oregon. The two oysters cultured are the Crassostrea gigas and the Ostrea lurida. Since oysters do not naturally spawn in Oregon waters the spat,...

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....

The role and policy implications of selected external factors as applied to the developmental patterns of five Wyoming fuels

Creator:: Vuk, Melvin M.
Abstract:: The developmental patterns of five fuel resources located within the state of Wyoming are examined through time and in relation to several factors external to the location of the fuels. An historic description and inventory of the five fuels: petroleum; natural gas; oil shale; coal; uranium are presented. External factors...

The role of the land developer in converting agricultural land to urban use: subdivisions in Tualatin, Oregon

Creator:: Avery, G. William
Abstract:: The study of the interactions between man and his environment is the eminent domain of the geographer. An excellent example of this kind of study is the urbanization of a formerly rural town on the urban-rural fringe. The area in this instance is Tualatin, Oregon, with the focus on the...

Spatial expressions of farm size changes in the Polk and Linn counties of Oregon

Creator:: Van Otten, George A.
Abstract:: The spatial organization of farm units in Polk and Linn counties in the mid-Willamette Valley has undergone significant change over the past 30 years. Whereas most study areas operations in the 1930's and 1940's consisted of small family owned farms with contiguous land bases, present mid-Willamette Valley units vary considerably...

The feasibility of applying air photo interpretation to the locating, analyzing and development of wind power sites

Creator:: Maule, Peter Anthony
Abstract:: If wind power is to become a viable energy alternative, a rapid and reliable cost effective methodology must be established, whereby large areas can be surveyed for windy sites and those sites can be evaluated. Based primarily on locating wind deformed vegetation, this paper establishes the feasibility of using air...

Watershed and climate influences on flood frequency distributions in the Willamette River basin

Creator:: Tolle, Timothy Victor
Abstract:: Problem areas identified are: The needs a) to develop curve fitting procedures to estimate flood flow distributions; b) to incorporate precipitation data into frequency analysis procedures; and c) to better define flood potentials for ungauged streams. Closely related to the above, it is noted that variables commonly used to estimate...
