Seasonal hydrodynamic pattern and effect of marine sediment distribution in Banten Bay

Abstract This study aimed to see the pattern of current velocity and direction at time high tide, low lowest tide during west east monsoons as well an increase in sedimentation. Oceanographic environmental baseline data used this consisted bathymetry, tides, winds, waves, ocean currents, sediment. The model was DHI MIKE 21 Flow Model FM. Based on calculation determining type using Formzahl formulation 1.54, tides area were classified single dominant mixed tides. In season, maximum 0.112 m/s with coming from northeast southwest approaching coast. highest concentration suspended sediment December when seawater conditions nearing tide. eastern part Pier 3 1120 g/m . most significant change bed level side where elevation +0.30 m decrease -0.40 m. From information regarding location abrasion sedimentation jetty development, it is possible know advance anticipation dredging plan mitigation coastal abrasion.
