Potential impacts of climate change on soil erosion vulnerability across the conterminous United States

Creator:: Segura, C., Sun, G., McNulty, S., and Zhang, Y.
Abstract:: Rainfall runoff erosivity (R) is one key climate factor that controls water erosion. Quantifying the effects of climate change–induced erosivity change is important for identifying critical regions prone to soil erosion under a changing environment. In this study we first evaluate the changes of R from 1970 to 2090 across...

Impact of land use patterns and agricultural practices on water quality in the Calapooia River Basin of western Oregon

Creator:: Mueller-Warrant, G. W., Griffith, S. M., Whittaker, G. W., Banowetz, G. M., Pfender, W. F., Garcia, T. S., and Giannico, G. R.
Abstract:: Agricultural practices, including tillage, fertilization, and residue management, can affect surface runoff, soil erosion, and nutrient cycling. These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and...

Cooperative Extension Compilation Report for the Dairy-McKay Hydrologic Unit Area, from 1991-2000

Creator:: Jordan, E., Buckhouse, John, Baggott, J., Rambo, Neil L., Dingus, C., and Smith, S.
Abstract:: In 1988 the Tualatin River was designated 'water quality limited' by the Oregon Department of Environmental Quality. Three sources of pollution: urban point source, forestry non-point source and agricultural non-point source pollution were considered to contribute unacceptable levels of nutrients (phosphates and ammonium nitrates) to the river. Since a significant...

Examining the voluntary adoption of agricultural conservation practices in northern Malheur County, Oregon

Creator:: Foley, Kelly M.
Abstract:: This study sought to better understand the voluntary adoption of water quality improving practices by agricultural producers in Northern Malheur County, Oregon. The Reasoned Action Approach/Theory of Planned Behavior was used as a theoretical framework to identify barriers and incentives to adoption. Study findings suggest that producers primarily consider practical...

Basin-wide distributed modeling of hydrologic responses to irrigation management in the Wood River Basin, Klamath County, OR

Creator:: Owens, Joshua M.
Abstract:: The Wood River Basin lies upstream of Upper Klamath Lake, the main reservoir of the USBR Klamath Irrigation Project that provides irrigation water to 210,000 acres of downstream land. Water allocation became a contentious issue in 2001 when drought led to curtailment of irrigation deliveries to the Klamath Irrigation Project...

Ecological land units of Bear Creek watershed and their relationship to water quality

Creator:: Mattison, Jeffrey L. and Buckhouse, John C.
Abstract:: During 1975 and 1976 a sedimentation study was conducted in the Bear Creek watershed, located in the southeastern corner of central Oregon's Crook County. A Rocky Mountain infiltrometer was used to simulate high intensity rainfall over 468 sedimentation plots. Rainfall and runoff were measured and a sample of the runoff...
