This portion of the USGS data release contains simulated nearshore wave parameters derived from a stand-alone spectral wave model of the Columbia River littoral cell, Washington and Oregon. The model output includes significant wave heights, peak wave periods, mean wave directions, and water depths for a series of 221 shore normal transects that extended from the coastline to the -15 m NAVD88 elevation (about 16.5 m average water depth). Data are provided at the seaward extent of each transect as well as at the location of the break point, or location just outside the surf zone, which varied dynamically based on the local bathymetry and wave conditions. Additional data are provided at four locations corresponding to the locations of buoy observations used to validate the model application. The data are derived from two hindcasts solved at hourly intervals between 1) August 2014 to September 2023 (h1), and 2) July 2010 to August 2011 (h2). The data from both hindcasts were compiled into netCDF files for the nearshore and buoy locations for distribution.
