This dissertation is concerned with the diminution of Oregon's Umatilla Indian Reservation over a 120 year period (1855-1975). Its objective is to show that the transfer of land from Indian to non-Indian ownership was most attributable to four casual factors:
(1) historical happenstance, including the passage of the Oregon Trail...
Importance of tenure structures is often ignored in agricultural
development planning in India. Emphasis instead is commonly
placed on agro-techniques for increasing productivity to meet the
growing needs of food supply. To evaluate the affects of institutionalized
tenure structure on agricultural efficiency, two pairs of contiguous
districts from Madhya Pradesh,...
The role of weather in influencing tourist-recreation visitation
to the Oregon coast during the six-month summer season of May
through October has been investigated by this research. In addition,
the normal day-to-day fluctuations in coastal visitation has been
determined.
Based upon the normal visitation, the tourist-recreation season
on Oregon's coast...
Based in part on previous work by this researcher, variables assumed to play a minor part in the process/ response system examined by the OSU Alsea Bay Hazard Study Team (1985-87)--river input and subsequent variations in hydrology--were more completely analyzed for their range of effects on the stability of Alsea...
The objective of this dissertation is to enhance the monitoring of forest ecosystems through the utilization of remotely sensed data to address the exigencies posed by the Anthropocene. On a global scale, rising temperatures and fluctuating precipitation patterns have strained forests and produced shifts in natural disturbance regimes. Additionally, the...
To assist with risk-assessment with deepwater and ultra-deepwater prospects for offshore energy extraction as well as provide a useful tool for oil spill response, a spatially-explicit model was developed for comprehensive simulations of a blowout event from the wellhead to final fate and degradation. The Blowout and Spill Occurrence Model...
The 2004 Indian Ocean tsunami raised concern among marine park managers and
hazard mitigation professionals about the significant impact of major coastal hazards
on marine park natural resources and ecosystems. The main reason for this concern is
the strong linkage of marine parks and their rich assortment of ecosystem services...
Due to recent changes in Oregon land-use regulations, agricultural
resource lands within exclusive farm-use zones are being designated
as high-value, important, or small-scale farmland according to their
relative potential for commercial agriculture. Potential gross
agricultural sales are used as a threshold in the designation of
small-scale farmlands; however, the regulations...
The purpose of the research is to develop a methodology
whereby an objective evaluation of the performance approach to land
use planning may be possible. The methodology includes questionnaires
and a field sheet that relate to the administration process of permit
application and indicators of quality in developments. The methodology...
Sea tide heights predicted one year
in advance are manipulated to give accelerations
in centimeters per second per kilometer for the
distances San Francisco to Humboldt Bay and
Humboldt Bay to Astoria. Comparison of these
accelerations to various earth-moon-sun lineups
shows the accelerations are controlled by the
29.53 day lunar...
