Flood damages are increasing as a result of frequent occurrence of large floods in many parts of the world, existing and continuing encroachment of development onto flood plains and aging flood protection structures. Under such circumstances, there is an ongoing search for better ways of protecting human life, land, property and the environment by improved flood management. Many flood management measures have been practiced in various jurisdictions, including living with floods, non-structural measures (e.g. regulations, flood defence by flood forecasting and warning, evacuations, and flood insurance), and structural measures (e.g., land drainage modifications, reservoirs, dykes and polders). Such flood management is difficult in river basins controlled by a single authority, and becomes even more challenging when dealing with transboundary floods, which may originate in one country or jurisdiction and then propagate downstream to another country, or jurisdiction.
