Despite various efforts aiming at disaster reduction, disasters don’t seem to show declining tendency, according to the factor that can be thought to be the following: - Abnormal weather due to global warming; - Concentration of population and assets in inundation areas; - Intensive use of land, including underground development; - Particularly in developing countries, rapid urbanization and poverty.

The challenges learnt through these flood disasters reported as an urgent recommendation by the Policy Committee for Torrents Countermeasures in December 2004 are as follows:

- The necessity of flood forecasting for small/medium sized rivers which have swift run-off characteristics, - The preparation for the natural forces exceeding the structural capacity, - The need for countermeasures of levee breach causing rapidly expanding disastrous phenomena, - The proper warning and evacuation system taking into consideration aging society, and also into underground spaces vulnerable to submergence, - The system leading to quick evacuation after evacuation advise and order.
