The phenomena of climate change interacts with the complexity of urban system, which reflect sptially on the process of urbanization. One of the effects of climate change is an increased flooding hazards, and when floods occur this has a severe impact on human lives and comes with vast economic losses. The city of The Hague aims to achieve the goal of becoming a resilient city in 2050. However, the city is under the threat of extreme precipitation and the challenge of urbanization, which affect the liveability in the city. As an important component of achieving resilience, rainproof adaptation can be transformed as an opportunity. By taking the complexity of the social and enviromental vulnerabilities into the consideration, the project discusses the possibility of linking the water management process with the public space design to develop a conversation of the techinical, spatial and social process. The focus of the graduation project is how precipitation flood management can collaborate with public space design to become an opportunity for achieving urban resilience. Taking the case of The Hague, the Netherlands, the project proposes a re-defination of urban development process through public space design with techinical water management approach.
