A Modeling Study of Coastal Sediment Transport and Morphology Change

摘要

Damon Point in Grays Harbor has experienced continued evolutiontowards the existing navigation channel and the land intrusion into theharbor posts potential threat to navigation and port operation.Numerical modeling study was conducted to investigate thehydrodynamics, sediment transport, and morphology change at theharbor near the navigation channel. Calculated waves, currents, waterlevels, sediment transport and long term morphology changes werecalibrated and validated with the field measurements. Hydrodynamicand morphodynamic analysis indicates that sediment transport due tothe land evolution will not result in significant depth changes in thenearby channel in the next 5 years.
