Soil‐structure interaction has been an area of active research since the 19th century and has evolved significantly over the past 150 years (Kausel, 2010). Previous soil‐structure interaction studies have been based on numerical simulations (e.g., Costantino et al. 1976; Jensen et al. 1999; Jensen, Edil et al. 2001; Jensen, Plesha...
This document presents the results from discrete element method (DEM) simulations of interface shear compared to previously published data from similar physical experiments. Rough shafts emplaced in granular assemblies are subjected to monotonic and cyclic loading and the results evaluated. The granular‐continuum interface behavior for different anchor surface roughnesses is...
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...

Abstract— This study describes the sound produced by a
hydrokinetic turbine operating in a riverine environment near
Iguigig, AK (USA). Drifting spar buoys equipped with
hydrophones and GPS loggers were used to characterize
temporal and spatial variability in turbine sound over a range of
turbine operating conditions. Because of the...
This project was carried out collaboratively by Oregon State University (OSU) and the Oregon Department of Geology and Mineral Industries (DOGAMI) and involved baseline observations and
modeling at the proposed wave energy conversion (WEC) array site near Reedsport, OR. In particular, observations and predictions of the wave conditions at the...
The Tertiary geologic evolution of the Oregon and Washington continental margin was molded by episodic periods of convergence between the Pacific oceanic plates and the North American plate. This margin is the site of a deep basin that is floored by Paleocene to lower Eocene oceanic crust and contains more...
A long-term energy storage technology is necessary to utilize Oregon’s curtailed renewable energy, an issue the state faces, even with a low percentage of renewable energy in the energy mix. This report proposes a system design that details how hydrogen power-to-gas technology can be used in conjunction with the existing...
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.
The Governor’s Advisory Group on Global Warming developed this Oregon Strategy for Greenhouse Gas Reduction.1 Governor Ted Kulongoski appointed the Advisory Group early in 2004 to perform this task. This Strategy, if implemented, will complement the agenda of the West Coast Governors’ Global Warming Initiative undertaken by the governors of...
This project was carried out collaboratively by Oregon State University (OSU) scientists and involved participation by Oregon Department of Fisheries and Wildlife and NOAA Northwest Fisheries Science Center scientists. The goal of this project was baseline characterization via observations and sample collection of the habitat and biological assemblages present at...
