NORTH JETTY COASTLINE EVOLUTION AND SHORELINE ENGINEERING, GRAYS HARBOR, WASHINGTON
AbstractThis study was initiated by the Port of Grays Harbor and the City of Ocean Shores, WA to address ongoing shoreline erosion processes, and sedimentation at the Grays Harbor Federal Navigation Channel. The North Jetty at the entrance to Grays Harbor Estuary, WA was constructed at the beginning of last century (1907) and resulted in major regional changes to the coastline. During the first 40 years post-construction of the jetty, approximately ten miles of sandy beach shoreline, two miles wide north of the jetty, was created by natural sediment transport processes. The accreted land was the base for the creation of the City of Ocean Shores. Since that time the shoreline has been periodically altered by extreme erosion events.
