| 内容記述 | A fully three-dimensional finite difference baroclinic model system for hydrodynamics and cohesive sediment transport is described. The hydrodynamic model is based on the hydrostatic and Boussinesq approximations. The simulation of cohesive sediment transport processes is performed solving the 3D-conservative advection-diffusion equation. The model is ECOMSED (Estuarine Coastal and Ocean Modeling System with Sediment) developed by HydroQual, Inc., (2002) which is applied to the transport of cohesive sediments in the Mahakam Estuary, East Kalimantan, Indonesia. The model was run for 15 days (27 June–12 July 2000) driven by tidal forcing at the open boundary and river discharge at the upstream. The observed temperature, salinity, and suspended sediment data were available for the start of the simulation. Good agreement was found between model results and observed temporal and spatial variations in water elevation, currents, and suspended sediment concentration (SSC) in the Mahakam Estuary. During the flood tidal condition, the tidal current advected the higher salinity water into the estuary, resulting in a relatively large salinity gradient inside the estuary. During the ebb tidal condition, the combined gravitational and tidal flows moved the low salinity water seaward from the upstream, leading to a rapid decrease of salinity near the mouth of the estuary. The simulation results of suspended sediment transport in the Mahakam Estuary nearly followed the salinity transport. The suspended sediments were mainly transported from Mahakam river towards Muara Pegah and Muara Jawa than Muara Berau and Muara Bayur. The SSC at Muara Jawa, Muara Pegah, and Muara Kaeli was mainly influenced by river discharge, meanwhile at Muara Bayur it was dominated by tidal current. | |||||
