A three-dimensional large-eddy simulation (LES) model was used to examine how stratified flow interacts with bottom obstacles in the coastal ocean. Bottom terrain representing a 2D ridge was modeled using a finite-volume approach with ridge height (4.5 m) and width (~30 m) and water depth (~45 m) appropriate for coastal...
"This guidebook is intended to serve as a reference to help local governments plan for the protection of wetlands and meeting the requirements of statewide planning goals, particularly Goal 5. This guidebook does not create any new policy; it only seeks to explain existing statutes and administrative rules. Background and...
According to the United States Geological Survey, 9 percent of wells in the Willamette Valley exceed the EPA’s 10 ppm drinking water standard for nitrogen in the NO3– compound, or NO3–-N. A study of 281 domestic drinking water wells in Lane County showed that 22 percent of the wells exceeded...
Forage production is of primary importance to Oregon’s livestock enterprises and agricultural economy. The forage is either grazed or conserved.
Conserved forage is needed to feed livestock in times of little forage growth—a key cost of livestock production. Extending the grazing season reduces the cost and time involved in feeding...
In order to understand the economics of the 2001 irrigation curtailment in the Upper Klamath Basin, and the prospects for lower-cost solutions
to future irrigation shortfalls, one must appreciate just how much the economic value of irrigation water varies from one piece of land to
another throughout the Upper Basin....
Since publication of the Oregon State University–University of California report on Klamath Basin water allocation,1 the Bureau of Reclamation (BOR) and Klamath Water Users Association (KWUA) initiated a pilot project to
compensate growers who agree to withhold irrigation from 12,000 acres of Project lands. This “Pilot Water Bank,” in place...
In the U.S., chickpeas commonly are used fresh in salads or in soup. Chickpeas are rich in protein, complex carbohydrates, and fiber, while
low in fat and cholesterol. Chickpea is a potential rotational crop and fits well in wheat and barley cropping systems. It is an option for cereal
farmers...
Climate warming may first show up in forests as increased growth, which occurs as warmer temperatures, increased carbon dioxide, and more precipitation encourage higher rates of photosynthesis. The second way that climate change may show up in forests is through changes in disturbance regimes—the long-term patterns of fire, drought, insects,...
