Weather-related extreme events have been intensified by climate change. Among these events, flooding has been the most frequent and affected the largest number of people in the world during 1998-2017. The consequences are particularly severe in urban areas due to complex infrastructure and dense population. Effective management of flood risk is critical for resilient cities, and collaboration among various stakeholders has been acknowledged for effective management. As governance framework seeks collaborative management, scholars and practitioners have discussed and applied diverse approaches of governance to flood risk management. Although the theoretical outcomes are more apparent, how to apply such approaches and what benefits to expect from their implementation are often elusive. This study reviews case studies of urban flood risk management around the world from 1989 to 2018. I particularly focus on: i) forms of collaboration, ii) key concepts (i.e., vulnerability, resilience, and adaptive capacity), and iii) a perceived connection of flood risk management with climate change and sustainable development. The study has found not only collaboration between multiple stakeholders but also combinations of structural and non-structural measures have been increasingly recognized over time in flood risk management. Moreover, vulnerability has been the term commonly considered in flood risk management, and resilience building has been underscored as a long-term goal. By reviewing case studies of the world’s different urban areas, I present the strategies and practices adopted to urban flood risk management. I also address lessons and challenges that can contribute to improving flood risk governance in urban areas.
