Proceedings of a workshop held at the Hatfield Marine Science Center, October 11-12, 2007. Edited by George W. Boehlert, Gregory R. McMurray, and Cathryn E. Tortorici.
A one-dimensional, implicit, finite-difference model is
developed, calibrated and verified for three estuaries along
the central Oregon coast. The model is used to generate controlled
data for a large number of hypothetical estuaries.
Two non-dimensional coefficients, K[subscript F], and. K[subscript I], are developed
incorporating physical characteristics of the estuary which...
This report summarizes the outcomes of a March 22-25, 2010, workshop in Seattle, Washington, on the environmental effects of tidal energy development. The workshop focused on building capabilities to evaluate the environmental effects of tidal energy from turbines placed in the water column throughout the United States. However, it did...
The number of wind turbines and wind farms in the Pacific Northwest has increased dramatically in the past six years, which represents a significant amount of electrical generation capacity connected to the public electric grid. However, the variable nature of wind sometimes introduces excessive power, or conversely shortages, in power...
Today's power systems are undergoing dynamic changes in their operation.
The high cost of capital improvements that include new generation and transmission
projects has prompted power system planners to look for other alternatives in dealing
with increased loads and overall system growth. A dynamic braking resistor is a
device that...
Tide-topography coupling is important for understanding surface-tide energy loss, the intermittency of internal tides, and the cascade of internal-tide energy from large to small scales. Although tide-topography coupling has been observed and modeled for 50 years, the identification of surface and internal tides over arbitrary topography has not been standardized....
Over the last 20 years, there has been rapid growth in the amount of installed wind power in the Pacific Northwest, specifically in the Columbia River Gorge. The variable and non-dispatchable nature of this resource requires that it be balanced in some form by other sources on the grid. In...
An innovative regional planning institution, the Northwest Power Planning Council, was created to plan for two conflicting water-related resources, fish and wildlife and electrical power. The Council is responsible for regional planning but implementation of those plans is largely the responsibility of four federal agencies and four state governments. As...
