Economics of drought preparedness and response in irrigated agriculture

Creator:: Peck, Dannele E.
Abstract:: The impact of recent severe droughts throughout the United States, the potential for climate change to intensify the frequency and severity of drought, and discussion about the future of government assistance in agriculture highlight the need for a transition from drought as ‘disaster’ to drought as ‘managed risk’. However, guidance...

Post-accident radiocesium uptake in eastern Oregon wheat crops : A preliminary estimate using a modified "PATHWAY" model

Creator:: Palotay, Joshua A.
Abstract:: An experimental environmental uptake model was developed for the purpose of estimating the final harvest concentration of contaminant following an acute accidental release of radiocesium onto an eastern Oregon winter wheat crop. The system was developed using the PATHWAY environmental uptake model as presented by Whicker and Kirchner (1987) for...

Stream Temperature Modeling for Marys River Watershed

Creator:: Mustafa, Mamoon
Abstract:: High water temperatures in rivers have detrimental effects on riverine water quality and ecology. In this study, two river temperature models, within the agricultural watershed model Soil and Water Assessment Tool (SWAT), were investigated for their ability to simulate water temperatures accurately throughout the year. The original temperature model within...

A spatially explicit model for allocating conservation efforts : the Grand Ronde River basin, Oregon

Creator:: Watanabe, Michio
Abstract:: The spatial and dynamic pattern of landscape changes has a profound effect on the supply of environmental services, including the provision of habitat for fish and wildlife. Spatial heterogeneity is a common feature of landscapes in the Pacific Northwest, most notably in areas important to the production of salmonid fish...

Simulating extreme total water levels using a time-dependent, extreme value approach

Creator:: Serafin, Katherine A.
Abstract:: Coastal flood hazard zones and the design of coastal defenses are often devised using either the maximum recorded total water level (TWL) or a 'design' event such as the 100-year return-level flood, usually projected from observed extreme events. Despite technological advances driving more consistent instrumental records of wave heights and...

Coupled wave and surge modeling of Tillamook Bay, Oregon : extreme events and climate change impacts

Creator:: Cheng, Tiffany Kay
Abstract:: Estuaries represent the confluence of land and ocean environments and encompass a number of complex interactions amongst tides, winds, offshore waves and the riverine contributions, all of which contribute to total water levels (TWLs). The study of TWLs and the relative weight of its components can assist local communities in...

Flow-Solute : A Tool for Exploring the Effects of Nitrogen Management in Alternative Future Scenarios

Creator:: Wentworth, Andrew Michael
Abstract:: Surface water quality is a growing concern in the Willamette River Basin and elsewhere. The region's growing population is dependent on the availability of clean water for drinking water, irrigation, wastewater dilution, and wildlife habitat. Watershed management to produce economic goods and environmental services requires an understanding of basic hydrologic...

Monitoring river restoration using fiber optic temperature measurements in a modeling framework

Creator:: Huff, Julie A.
Abstract:: The Middle Fork of the John Day River (MFJD) in Northeastern Oregon contains important spawning grounds for spring Chinook and summer steelhead of the Columbia River Basin. In the summer of 2008 phase one of a river restoration project was completed which included the addition of engineered log jams (ELJs)...

Water quality modeling of the Tualatin River

Creator:: Berger, Christopher J. (Christopher John)
Abstract:: Water quality problems related to excessive algal growth, high nutrient loading, and low flows have been occurring along Oregon's Tualatin River. The Tualatin River is 86 miles long and has a drainage basin of 711 square miles. The drainage basin incorporates forest, agricultural, and urban areas. Located in the Portland...
