Six years ago, Nagasaki City was attacked by heavy rainfalls which caused the death of many and enormous property damages. After this disaster many projects have been carried out in order to prevent and/or mitigate the damages according to debris flows or inundation by floods. Namely, several sand disaster prevention facilities have been constructed on mountainous regions and river improvement works carried out (known as "hardware" prevention). At the same time, warning and refuge programs should also be proposed (known as "software" prevention). Recently, we have been studying about the mechanism of flash flows, and have tried to simulate them mathematically by computer in order to make up maps of inundation for both actual and predicted floods. These results are undoubtedly useful as an information for disaster prevention and/or mitigation. In this paper, the results of "the Survey of Awareness and Practice for Flood Disaster Prevention" answered by foreigners in Nagasaki have been discussed on the purpose of disaster prevention and/ or mitigation. The International Decade for Natural Disaster Reduction (IDNDR) will start soon and it is to be hoped that the warning system will thoroughly be completed by this occasion.
