Both the Netherlands and Japan are threatened by coastal flooding, fluvial and pluvial flooding need to be considered in urban engineering, landscape architecture and urban design. For the Netherlands, this is a very prominent threat as large parts of the country are below sea level and the precipitation patterns change in such a way that the pluvial flooding occurs more often. In Japan, most of the population centers (e.g. Tokyo, Osaka) are in coastal areas that are threatened by risks of coastal storms, typhoons and tsunamis, moreover, they suffer from earthquakes. In the future, the coastal flood risks and pluvial and fluvial flood damage are expected to increase due to increased urbanisation, economic growth, changing precipitation patterns and sea level rise. In recent decades’ new scientific concepts for assessing and managing risks have been developed, but many questions remain and policy implementation of new concepts is often lacking. In addition, the link between the larger and smaller scale especially concerning vital subsurface infrastructure is due to lack of interdisciplinary working between hydraulic engineering, urban design and urban water management not been fully exploited. How can we change this to create more efficient and innovative design process to fight the future damages by the environmental disasters. To face this challenge, there was an interdisciplinary and international students workshop lead by TU Delft in collaboration with Chiba University, Tokyo University in Tokyo, Japan. This was a part of a joint seminar between a group of hydraulic engineers from TU Delft lead by Professor Jonkman, and Technical Institute of Tokyo. The aim of the workshop was to research and evaluate the existing infrastructure in the urban floodplain in Edogawa ward, Tokyo by using the research method of “Research by Design”, and compare it to the existing condition in Rotterdam. The participants of the workshop were students of urban design, architecture, landscape architecture, sustainable design, hydraulic engineeringg from 7 different nationalities. The exhibition “Challenges in Flooding Study of Multi-Disciplinary International Design”presents this result of the 3 day workshop to hold a place for a discussion about interdisciplinary design process and also the future collaboration between the Netherlands and Japan, and engineers and designers to face the challenges in flooding.
