Abstract

Urbanization has changed the land use from pervious cover to impervious cover which have an impact on increasing runoff in urban areas. The objective of this study is to determine the effectiveness of spatial distribution of Green Infrastructure (GI) in reducing runoff under various design storms. Simulation of runoff reduction is carried out by implementing the GI in the catchment area located in Pondok Kelapa, Eastern Jakarta, Indonesia. EPA SWMM 5.1 was used to simulate the performance of GI on reducing runoff in the study site for two simulation scenarios: baseline scenario (current conditions) and GI scenario (implementing rain garden and rain barrel). The results show that GI compared to the baseline under various design storms 2-year, 5-year, 10-year, 25-year and 50-year return periods reduce the total runoff volume approximately 9.67%, 8.92%, 8.49%, 7.94%, 7.54%, respectively.
