“…To overcome flooding disasters, the construction of the GSW has been proposed for Jakarta Bay. The construction of the GSW will slightly increase the maximum tidal range by 0.01 m [1] because of the reduced tidal prism by 20% and increased tidal choking in the bay. In scenario 3, the total inundation areas of Jakarta Bay are 33.47 km 2 (7.97% of the total land area), increasing by 1.11 km 2 from scenario 1.…”

“…The influence of river discharge and sea level rise on the hydrodynamics of the bay was investigated through numerical modelling. The hydrodynamic model ( Figure 1) in this paper was based on the model previously established by Rusdiansyah et al [1], with the model domain being expanded to cover the entire area as described in the Master Plan National Capital Integrated Coastal Development [8]. The impacts of river discharges and sea level rises were analysed using numerical experiments in this study.…”

“…Jakarta Bay is an open type bay ( Figure 1) with a water depth less than 60 m. Surface currents in Jakarta Bay are mainly in an east to west direction during spring tides, with peak current speed occurring at the bay mouth and near the river mouths (Figure 2a,b) [1]. Inside the bay, the current speed is mainly below 0.2 m/s.…”

“…Jakarta Bay is located on the northwest coast of Java Island, extending from 5.8 • S to 6.2 • S and 106.6 • E to 107.1 • E [1]. It is a shallow bay with an average depth of about 18 m and an area of 662 km 2 [2].…”

Jakarta city has been vulnerable to sea level rise and flooding for many years. A Giant Seawall (GSW) was proposed in Jakarta Bay to protect the city. The impacts of sea level rise and river discharge on the tidal dynamics in Jakarta Bay and flooding areas in Jakarta city were investigated using the finite-volume coastal ocean model (FVCOM). Model results showed that the bay is diurnally dominated by the K1 tidal component. The diurnal tides propagate westward, while the semidiurnal tides propagate eastward in the bay. The rise of sea level increases the diurnal tidal component and the inundation areas due to the increased tidal forcing: when considering a sea level rise of 0.6 m, the K1 amplitude increases by ~1% (0.25 cm) near the coastline and the current magnitude increases by 16.6% (0.05 m/s). The inundation area increases with the sea level rise in the low land elevation areas occurring near the coastlines: the inundation area increased by 29.68 km2 (7.1%) with a sea level rise of 0.6 m. The increase of river discharge amplified the diurnal tidal component as well as the inundation areas at the river mouth due to increased fluvial forcing: if 10 times the mean river discharge occurs, the K1 amplitude increases by ~1% (0.25 cm) and the current magnitude increases by 100% (0.4 m/s), and the inundation areas increase by 26.61 km2 (6.2%). The K1 tidal phase remains almost unchanged under both the sea level rise and river discharge conditions. The combined increase of sea level rise and the river discharge amplifies the inundation areas and the tidal currents due to increased tidal and fluvial forcing. The construction of GSW would decrease the tidal prism and dissipation effects of the bay, thus slightly increasing the K1 amplitude of the tidal level: by less than 1% (0.2 cm). There would be no significant change of phase lag for the K1 component. Although this study is site specific, the findings could be applied more widely to any open-type bays.

The 9th International Workshop on Modeling the Ocean (IWMO 2017) was held in the modern campus of Yonsei University, Seoul, Korea, from July 3-6 2017. The workshop was attended by about 80 participants from countries all around the world, many of whom were young and earliercareer scientists: students and postdocs. Papers were presented covering a broad range of topics on field observations, analyses, and modeling: wave and air-sea interaction dynamics, climate variability, basin-scale processes and coastal oceanography, sea-ice dynamics, sediment transport, tropical cyclones, biogeochemical-physical coupling, boundary currents, sea-level rise, extreme events, ocean prediction and others. We were pleased to witness very high-quality research and presentations, many from young students and scientists. Thirty three (33) young scholars participated in the Outstanding Young Scientist Award (OYSA) competition; congratulations to all of them! The finalists of the IWMO-2017 OYSA were: R

Modelling compound flooding: a case study from Jakarta, Indonesia

et al. 2023

The paper investigates compound flooding from waves, sea surge and river flow in northern Jakarta, Indonesia, which is a global hotspot of flooding, by combining process-based coastal and river models. The coastal hydrodynamic modelling of Jakarta Bay in Indonesia shows that coastal storms can lead to a substantial increase in sea water level due to wind and wave setup in the nearshore areas, including Muara Angke river inlet. The compound flood hazard from a range of flood scenarios was simulated and analysed. The results reveal that low-lying areas around the river inlet are prone to flooding even during regular, low-intensity storm events, while rarer storms caused extensive floods. Floods were not caused by direct overwashing of sea defences but by overspill of the banks of the river inlet due to high sea water level caused by wind set up, wave setup, and sea surge obstructing the drainage of the river and elevating its water level during storms. We also found that the sea level rise combined with rapid land subsidence will inundate the existing coastal flood defences during storms in future. The majority of the city will be below mean sea level by 2100. The overflow of existing coastal defences will lead to extensive flooding in northern, western, and eastern Jakarta unless the defences are upgraded to keep up with future sea level rise.
