CIRIA have produced two great little animations that help explain how to manage water in urban spaces through mimicking ecosystem process in natural watersheds. Not only does this create space for nature and biodiversity in our urban environments, it also means we gain benefits from  nature as wide ranging as reducing flood risk, cooling our urban environment in summer and making our environment more enjoyable to experience.

Water Sensitive Urban Design, along with the immediate benefits for people and wildlife also helps us adapt to the likelihood of more frequent sudden weather events as a result of global changes in climate and theirfore helps reduce environmental risk and build resilience into our urban systems.
