| Popis: | The Jakarta Bay artificial island reclamation is a part of the spatial arrangement of the Provinceof DKI Jakarta which is stated in Governor Regulation No. 121/2012. The regulation divides the area into threesub-regions, west, middle and east. In the middle sub-region, the influence of the reclamation of artificialislands, named I, J, K, L and M islands, on the tidal elevation and tidal current is investigated usinghydrodynamic modeling with inputs of the river discharges coming into the bay. The plan to build a gate at thesouthern side of L island is also a part of the study. For normal river discharge, the existence of the reclaimedislands does not influence the tidal elevation significantly, whereas the tidal current is affected by a 200%intensification at a few points. For flood river discharge with a 25-year return period, the tidal elevation is moreunstable, with the maximum rising or falling by 2 cm at most locations. The current phase shift is found, andalong with the current intensification of round 200%, there is a reduction of the current magnitude. Thereclamation and the gate cause some tidal changes, although these are still within the normal range that canaccommodate daily activities. The reclamation scenario with the gate is better for the channel at the easternside of L island since it results in a lower tidal elevation.Keywords: Numerical modeling, Coastal environment, Tidal elevation, Tidal current, Jakarta Bayreclamation. |
