Study on effectiveness of flood control based on risk level: case study of Kampung Melayu Village and Bukit Duri Village

Abstract

Abstract. Jakarta, the capital city of Indonesia, experiences flood which causes activities disruption and losses almost every year. Many studies have been done to mitigate the impact of flooding. Most of them focus on reducing the inundated area as an indicator of the effectiveness of flood control. This study aims to evaluate the effectiveness of several flood control alternatives based on risk level reduction. The case study is located in Kampung Melayu Village and Bukit Duri Village which are densely populated with several economic area and almost every year experiencing severe flooding in Jakarta. Risk level analysis was carried out by the method based on guidelines issued by the Head of National Disaster Management Agency (BNPB) No. 2/2012 with few modifications. The analysis is conducted on five alternatives of flood control which are diversion channel to East Flood Canal (KBT), diversion channel to the West Flood Canal (KBB) in Pasar Minggu, river improvement, capacity enhancement on all components, and capacity enhancement focusing on one component. From the results, it is showed that enhancing capacity which focus on preparedness component by two levels are the best in terms of investment value to risk level reduction.

What are the Essentials for Community Resilience against Recurring Floods?

“…Kebon Baru is in the Tebet subdistrict of South Jakarta, while Kampung Melayu is in Jatinegara sub-district of East Jakarta. Approximately 62% of this area is inundated by yearly floods, causing high population exposure [4]. The two villages have similarities in socio-economic characteristics despite the different administrative municipalities.…”

“…Moreover, there has been an increase in the frequency of occurrence and expansion of inundated areas year by year [1]. This is due to the impacts of climate change, which affects the weather pattern and rainfall extremes [2], amplified by several other flood drivers, including the conversion of conservation areas into built land use [1], [3], inadequate drainage capacity [4], [5], and land subsidence [6]. To top off these physical factors, ineffective river management due to transboundary barriers and multi-level governance could not cope with the complexity of the urban issues resulting in the increasing risk of flood in Jakarta [7]- [9].…”

A review of structural approach to flood management in coastal megacities of developing nations: current research and future directions

“…The effectiveness of several flood control interventions in Jakarta, including investment in diversion channels, river improvement and capacity enhancement, have also been comparatively assessed using risk level analysis (Farid et al 2017). This study was useful in highlighting the best solution in terms of investment value to risk level reduction.…”

Assasment of flood hazard reduction in DKI Jakarta: Bendungan Hilir Village

“…This water system is the lifeblood of Jakarta's flood control. Kusuma et al [1], Formanek et al [2], Farid et al [3], conclude that as most of the flood management in the urban area of Indonesia, the flood management in Ciliwung River facing erosion, sedimentation, and land-use change problems. The land-use change in the upper part of the Ciliwung River tends to increase the rate of not only its extreme discharge but also its erosion and sedimentation.…”
