Numerical Modeling of Coastal Dredged Material Placement Study at Noyo Harbor, CA

摘要

This paper describes the numerical modeling of nearshore placement ofdredged material at Noyo Harbor, CA. The numerical models includethe US Army Corps of Engineers (USACE) Short-Term FATE model(STFATE), Coastal Modeling System (CMS), and Particle TrackingModel (PTM). The STFATE simulates the spatial distribution ofdredged material in open water after it has passed through the watercolumn on release of the barge load. The CMS calculates wavetransformation, flow circulation, water levels, sediment transport, andmorphology change. The modeling provides technical informationnecessary to evaluate a location site that is economically feasible forthe optimum sediment placement. The model simulation showed smallonshore sediment transport in typical summer and winter months. Thecalculated fine sediment transport during the dredged material releaseat the placement site indicated more longshore movement as the resultof strong wind driven current along the coast.
