Shore protection structures in Oregon : An analysis of demand and the implementation of engineering recommendations

Creator:: Chenault, Carla Diane and Chenault, Carla D.
Abstract:: Stabilization structures are the most commonly used form of shore protection along the Oregon coast. Eighty-five percent of the hard stabilization structures built in Oregon from 1976 – 1999 were riprap revetments. An evaluation was conducted of 143 riprap revetments in the northern three counties of Oregon. Clear trends exist...

Ocean electric energy extraction opportunities

Creator:: Zhang, Heng
Abstract:: The world's oceans contain tremendous renewable energy potentials. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world [1]. This thesis provides a comprehensive description of the state-of-the-art of ocean energy extraction technologies and lessons learned from...

Wave propagation processes at the mouth of the Columbia River

Creator:: Andes, Lisa (Lisa Christine)
Abstract:: The mouth of the Columbia River (MCR) has a longstanding reputation of hazardous navigational conditions. This reputation has been developing since the first ship, the Columbia, traversed through the inlet in 1792. The hazardous conditions are related to the large waves and strong tidal currents that are common in the...

Investigation and comparison of generators for dynamic operation in ocean buoys

Creator:: Schacher, Anthony Clinton
Abstract:: A significantly untapped renewable energy source exists in the world's oceans. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world. Ocean energy extraction is an old concept, and it is currently seeing the benefit of advancing...

A direct-drive wave energy converter with contactless force transmission system

Creator:: Agamloh, Emmanuel B.
Abstract:: Commonly proposed ocean wave energy converters (OWEC) use inefficient and maintenance demanding intermediate hydraulic and pneumatic systems. We propose a novel rotary direct-drive OWEC that eliminates these intermediate stages. The new device employs a contactless force transmission system (CFTS) comprising a “piston” and a “cylinder” and a ball screw to...

Mantle melting and heterogeneity along mid-ocean ridges : insight from basalt geochemistry along axial depth and morphologic gradients for intermediate spreading rate systems

Creator:: Russo, Christopher J.
Abstract:: This investigation focuses on gaining a better understanding of the complex relationship between melt generation, source variability and mid-ocean ridge morphology. The approach adopted here uses a variety of geochemical techniques to evaluate the ability of 'global' models to predict regional scale geochemical variability associated with axial depth and axial...

Engineering design knowledge management and capture using a process overview document

Creator:: Zarins, Andis M.
Abstract:: An experiment was conducted to examine the possible impact of an engineering design and problem solving process overview document on knowledge management and capture. A process overview document was first created. Next, two multi-disciplinary design teams worked over a two-week span to develop concepts to address a problematic opportunity. One...

A linear test bed for characterizing the performance of ocean wave energy converters

Creator:: Hogan, Peter M.
Abstract:: Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...

Scaled modeling and simulation of ocean wave linear generator buoy systems

Creator:: Gore, Ganesh P.
Abstract:: Accurate scaled modeling and simulation are critical to advancing ocean wave linear generator buoys. A 100th scaled model of ocean wave generator buoy systems is analyzed by solving the Navier-Stokes equations. These equations are numerically solved using Computational Fluid Dynamics (CFD) by implementing the front capturing method. In this thesis,...

Remote measurements of waves and currents over complex bathymetry

Creator:: Chickadel, Carmine C. (Carmine Christopher)
Abstract:: Waves are the primary input of energy in the nearshore region, and together with the currents forced through the transfer of momentum that occurs during the wave breaking process they are the principal mechanism for sediment transport in the nearshore. The basic physics of waves and currents are thought to...
