Evaluation of Breakwaters and Sedimentation at Dana Point Harbor, CA

Abstract

A flow, wave, and sediment transport model, the Coastal Modeling System (CMS), was applied to evaluate current and sedimentation patterns at Dana Point Harbor on the southern California coast. The permeability of breakwaters is the main interest in the study for the structural integrity and functioning to protect the harbor. Two Acoustic Doppler Current Profilers (ADCP) were deployed in November 2009 to collect current, water level, and wave data inside and outside the harbor. The model was validated by the field measurements. Wave transmission, flow penetration, and sediment seepage through the breakwaters were verified by the historical dredging information.
