Developing the city with water: managing resources and coping with the risk of flooding
In France, 1 in 4 people and 1 in 3 jobs are exposed to the risk of flooding, through overflowing watercourses or rising sea levels[1]. In more general terms, floods are a major natural hazard in several regions of the world. These risks are now accentuated by climate change and the increase in extreme weather episodes, including intense rain events in particular. In an urban environment, characterised by a strong increase in soil impermeability, these phenomena promote runoff and associated pollution and lead to congestion and flooding. In addition, urbanisation in flood-prone areas is a major economic and social issue for local communities. To meet these challenges, new approaches are being developed to provide better ways of living with water in cities.
