Abstract

Flood risks associated with changes in land use and cli�mate are a common concern, especially in relation to their potential effects on many cities around the world. Jakarta is a typical urbanized Asian city in Indonesia where flooding presents a consistent challenge. This study aimed to quantify the effects of land use and cli�mate change using a flood inundation model to ana�lyze future urban growth and climate change scenar�ios. The projected rainfall data of RCP2.6-SSP1 and RCP8.5-SSP3, based on the WRF simulation, were used as inputs for rainfall-runoff and flood inunda�tion simulations in Jakarta. In addition, RCP2.6 and RCP8.5, without urban development scenarios, were investigated to determine the effects of urbanization in Jakarta. The results showed that rainfall inten�sity, peak discharge, and flood inundation generally increased in the high RCP and SSP future scenar�ios. Significantly, the RCP2.6-SSP1 scenario showed a higher peak discharge value than RCP8.5, owing to the combination of land-use change and increased rain�fall. We conclude that the effects of urban develop�ment on atmospheric and runoff processes should be considered in climate change studies in urban areas.
