Abstract: It is widely accepted that sustainable development is the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. However, the question of how to apply this principle to flood management remains insufficiently answered. This article outlines a new strategic concept termed as “Flood Sharing” as a means toward sustainable flood management. Contrary to the traditional concept of flood confinement or blocking, the new concept advocates the need to alleviate flood damage by reducing inundation depth via expanding flood inundation areas. It differs from other contemporary thinking such as “make space for water” and “room for the river” in its emphasis on using the urban fabric. Evidence from a case study was presented to support this new concept, and model/data analyses have been conducted to show that it could be realized through the wise use of infrastructure.
