The Biggest Flooding Crisis in the World

We have to rethink how these cities are but the big crisis is also the fact that these cities are built. How do cities adapt with that situation where they have things that exist and are big and immovable? And then ot a larger scale of both in terms of the city scape itself or the cachments that exist in bengloro. We really need to think about the major hydrologic arthways that need to be maintained so that the we will have greater ability to deal with and reduce the risk of flooding in the future.
