Sediment transport process mecanism in estuary channel of Barito River South Kalimantan was simulated by using one dimension numerical model. The numerical model consists of hydrodinamic and convection — dilution transport equations. Hydrodinamic equation is solved by using Duflow program and convection — dilution transport equation was solved by using Central Scheme and Upwind. Hydrodinamic simulation was executed 3 x 24 hours and last 14 hours of simulation results are calibrated to field data. The result show suitability to hydrodinamic mecanism that occurred at field. Sediment transport simulation still show availability small different with field datas, but trend still remain adjusment. The sediment transport simulation was used to know siltation rate in access channel of Barito River.
