EVACUATION SIMULATION FOR A VULNERABLE COASTAL COMMUNITY IN JAKARTA

Coastal communities in developing countries are faced with an increasing risk of coastal floods because of various factors, such as sea level rise, coastal erosion, poor defense structures, and land subsidence (see Figure 1). In addition, an increase in the number of coastal residents due to population growth means that the number of residents without disaster experience and awareness is also increasing. To mitigate the potential damage due to future flood events it is necessary for coastal engineers and planners to evaluate the risk to each coastal community and inform local residents of the results of such exercises. The authors have been investigating one coastalcommunity in Jakarta, the capital city of Indonesia, as a typical coastal community which is at risk of coastal floods (see [1] and [2]). The results of the investigation so farshow that proper actions against possible flood scenarios, such as raising dykes, planting mangroves, and preparing evacuation plans, are needed to lower the potential overall risks. In the present paper, an evacuation simulation of how residents of the community are likely to behave in the event of flooding was carried out, which can be considered as a useful tool for evacuation planning.
