Zusammenfassung:Damon Point in Grays Harbor has experienced continued evolution towards the existing navigation channel and the land intrusion into the harbor posts potential threat to navigation and port operation. Numerical modeling study was conducted to investigate the hydrodynamics, sediment transport, and morphology change at the harbor near the navigation channel. Calculated waves, currents, water levels, sediment transport and long term morphology changes were calibrated and validated with the field measurements. Hydrodynamic and morphodynamic analysis indicates that sediment transport due to the land evolution will not result in significant depth changes in the nearby channel in the next 5 years. To be presented at the Twenty-third (2013) International Ocean (Offshore) and Polar Engineering Conference in Anchorage, AK 30 Jun-5 Jul 2013. Prepared in collaboration with the US Army Corps of Engineers, Seattle District, WA and in cooperation with the 2Department of Marine and Environmental Systems, Florida Institute of Technology, Melbourne, FL.
