This study quantifies the short-term effects of low-, moderate-, and high-severity fire on carbon pools and fluxes in the Eastern Cascades of Oregon. We surveyed 64 forest stands across four fires that burned 41,000 ha (35%) of the Metolius Watershed in 2002 and 2003, stratifying the landscape by burn severity...
Tsunami force and pressure distributions on a rigid
wall fronted by a small seawall were determined experimentally
in a large-scale wave flume. Six different
seawall heights were examined, two of which were exposed
to a range of solitary wave heights. The same
experiment was done without a seawall for comparison....
Recent natural disasters around the world including
both tsunamis and hurricanes, have highlighted the inability
of wood buildings to withstand wave and surge
loading during these extreme events. Little is known
about the interaction between coastal residential light-frame
wood buildings and wave and surge loading because
often little is left...
A definition is suggested for affine symmetry tensors, which generalize the notion of affine vectors in the same way that (conformal) Killing tensors generalize (conformal) Killing vectors. An identity for these tensors is proven, which gives the second derivative of the tensor in terms of the curvature tensor, generalizing a...
The potential for creating underwater noise disturbance is one environmental impact that must be accounted for by wave energy developers to meet the needs of regulatory agencies. This review study has been conducted to provide a concise knowledge base of the expected underwater noise conditions in the near shore environment...
Offshore wave conditions along the Oregon coastline are measured at a handful of buoy
locations where directional wave information is available. Most of these buoys are located in
deep waters and incoming waves undergo changes as they travel from deep water onto the shelf
where wave energy conversion arrays are...
In February 2009, the Oregon Wave Energy Trust kicked off a project titled the Utility Market Initiative (UMI). The project's purpose was to initiate a process to align the needs of the regional electric utilities with the resource potential of the wave energy industry. Pacific Energy Ventures' proposal that include...
This project is investigating whether low rate (goal: one pound per acre) early fall Contans applications to flailed diseased residues left on the soil surface can increase Cm inoculum and reduce Ss sclerotial viability.
