This study examines the effect of the reclamation of Jakarta Bay on sea level generated by storm tide. Simulation using Regional Ocean Modeling System (ROMS) with tidal source data from The Oregon State University TOPEX / Poseidon Global Inverse Solution Tidal Model Version 7.2 (TPXO 7.2), wind and atmospheric from European Center for Medium-Range Weather (ECMWF) Interim Re-Analysis (ERA-Interim) with 1/8o resolution. Simulation is done two stage with scenario before and after reclamation. The sea level of the model results is harmonically analyzed and re-predicted to separate astronomical and non astronomical factors. Changes in sea level were obtained by subtracting after with before reclamation of Jakarta Bay scenario. The results show that the elevation change after the reclamation of Jakarta Bay. Elevation of Jakarta Bay can be either an increase or a decrease. On November 26, 2007 at 18.00 WIB, there was an increase in total elevation throughout the reclamation of Jakarta Bay area and the biggest change is 11,53 cm (Bekasi). Meanwhile, the total elevation decrease occurred on 26 November 2007 at 01.00 WIB at -8.78 cm (between Island B and mainland Jakarta). Reclamation of Jakarta Bay caused tidal range changes and the greatest changes occurred in Bekasi at 22.4%.
