The delineation of landslides in the Lincoln County, Oregon coastal zone

Creator:: Gentile, John Richard
Abstract:: A study conducted along the Lincoln County, Oregon coast delineated the exact location of 153 landslides. The landslides were found through the interpretation of aerial photographs. Each landslide was verified in the field and its class (ancient, historic, recent), type (slump, debris slide or flow, planar slide), and status (stable,...

The economics of western juniper management on ranches located in the John Day Ecological Province of north-central Oregon

Creator:: Aldrich, Gwendolyn A.
Abstract:: Western juniper (Juniperus occidentalis Hook) is a species of juniper native to arid regions of the Pacific Northwest. The western juniper tree has a number of competitive strategies that, in conjunction with an almost complete removal of fire from the ecosystem, have resulted in a significant expansion of its population...

Shallow aquifer characteristics adjacent to the upper Middle Fork John Day River, eastern Oregon

Creator:: Hopson, Richard G.
Abstract:: Subsurface inputs into lotic systems are a primary mechanism for cooling streams with high ambient water temperatures. Objectives of this study include: 1) to determine the effectiveness of Forward Looking Infrared (FLIR) thermal imagery to detect shallow aquifers, 2) to characterize certain physical, spatial, and temporal characteristics of the fluvial,...

The optimal allocation of watershed conservation funding : a case study of the John Day River Basin, Oregon

Creator:: Skelton, Katharine
Abstract:: This study determines the optimal allocation of watershed conservation funds in the John Day River Basin, Oregon. Fund managers can use a variety of targeting schemes to allocate their limited resources. Depending on which targeting criteria is used, they may or may not be achieving the maximum environmental benefits per...

The iterative thermal emission Monte Carlo method for thermal radiative transfer

Creator:: Long, Alex R.
Abstract:: For over 30 years, the Implicit Monte Carlo (IMC) method has been used to solve challenging problems in thermal radiative transfer. These problems are typically optically thick and di ffusive, as a consequence of the high degree of "pseudo-scattering" introduced to model the absorption and reemission of photons from a...

A bioeconomic analysis of altering instream flows anadromous fish production and competing demands for water in the John Day River basin, Oregon

Creator:: Johnson, Neal S.
Abstract:: The growing demand for water in the arid regions of the West increases the need for optimal allocation of water among competing uses. An efficient allocation of water between instream and out-of-stream uses has been impeded by institutional constraints and the scarcity of information regarding instream flow benefits. The objectives...

The value of short run in-stream temperature forecasts : an application to salmonids in the Klamath and John Day Rivers

Creator:: Huang, Biao
Abstract:: Water temperature is an important measure of water quality, as well as a dominant factor affecting aquatic life within the stream environment. Elevated water temperatures can decrease the survival rate of fish in each life stage. Cold water species, such as salmonids, are particularly susceptible to elevated water temperatures. For...

Bacteria-phosphate interactions in Upper Klamath Lake sediments

Creator:: Harrison, Michael John
Abstract:: Interactions between sediment bacteria and available phosphate necessary for algal production in a eutrophic lake were studied. Twenty percent of the organisms isolated solubilized phosphate forms such as CaHPO₄, Ca₃(PO₄)₂, FePO₄, Mg₃(PO₄)₂ and Al₂(PO₄)₂. Solubilization of phosphates occurred under conditions of aerobic growth. Upon quantitative analysis, some isolates were capable...

The geography of the apple industry of the Chelan Valley, Washington

Creator:: Detering, Floyd John
Abstract:: 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...

Modeling surface water and groundwater interactions near Milton-Freewater, Oregon

Creator:: Petrides Jimenez, Aristides Crisostomos
Abstract:: The gravel aquifer of the Oregon side of Walla Walla River Basin has a strong hydrologic connection to surface water through a series of springs, unlined irrigation canals, the Walla Walla River, numerous wells and, since 2004, artificial recharge to the shallow aquifer using infiltration basins. The finite element Integrated...
