Circulation and Shoaling Study of the Port of Astoria

摘要

The objective of this paper is to develop an understanding of the circulation patterns of currents in the vicinity of the harbor slips at the Port of Astoria. Such an understanding is a necessary prerequisite to conducting research into the mechanisms which cause sedimentation to occur. The study used numerical and physical models to predict currents, circulation patterns and flushing rates for the port area. The models were followed up by a field study to verify the results of the simulations. Finally, a numerical sedimentation model was considered in an attempt to estimate the rate of sedimentation in the harbor area.
