Abstract. Due to massive development in the urban and rural areas, there is a dramatic increase in the impacted area and the amount of economic loss from the Ciliwung River Floods every year. Even though several research studies have identified the key drivers of the flood risk along the Ciliwung River Basin (CRB), addressing the problem has been limited to administrative boundaries. Because Ciliwung River Basin crosses two provinces and several cities and regencies, it is important to tackle future flood events using a transboundary approach. This study uses MICMAC analysis to recognize strategic flood risk drivers from key stakeholders' perspectives. In this study, 13 significant flood drivers were identified. Among those drivers, lack of control of spatial plans and weak stakeholder coordination and cooperation are found to be the critical drivers which influence all other flood drivers. Finally, this study proposes that a national-level development control regulation and an acting commission are established as a priority action for transboundary flood risk management in Ciliwung River Basin.

Transboundary river management for inter-city or inter province become very critical issue due to the ego sectoral and lack of responsibility sharing. This paper has recognized the most strategic flood risk driver from key stakeholder perspective.
