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 likely to be deployed. These changes can be in the
form of wave focusing or defocusing due to the presence of underwater banks, shoals, or
canyons. Also, wave dissipation mechanisms such as bottom friction or wave breaking can be at
play. Wave models can take into account such processes and produce predictions of the local
conditions at the site of a wave energy conversion (WEC) array. Knowledge of local conditions
can aid in the design of the devices for the specific local conditions to which they will be
subjected and can also provide advance knowledge of wave conditions to power companies once
a WEC array is in place.
The work performed herein was geared towards two goals. First, transformation of the wave field from
deep water to the site of the buoy deployment was assessed. Second, preliminary predictions about the
potential impact of the buoys on the wave field are made. The results are discussed separately below.
