| Outline of Final Research Achievements |
The causes of the Shaolin Village disaster are the occurrence of a deep-seated landslide, of cause, and the loss of the No.8 Bridge to connect neighbor safe village at about 10 hours before the occurrence of the landslide. The loss of the bridge was caused by aggradation of riverbed. However, based on the field observation on hydrological characteristics of the basin the No.8 Bridge crossing and numerical simulations of sediment runoff and riverbed evolution in the basin, the rainfall during Typhoon No.8 could not cause the loss of No.8 Bridge and rainfalls before Typhoon No.8 might act important rule for aggradation of the riverbed. These results say that, when we discuss about the warning and evacuation strategy to avoid the disaster like Shaolin Village disaster, it is necessary to take into account not only the occurrence and moving of deep-seated landslide but riverbed evolution in the period of heavy rainfall to assess the allowable bed level and safe evacuation route and site.
