The forming process cont ain two p art s, that one is rock avalanche and landslide of side wall of valley, and the other is debris flow forming activat ed by rainstorm. T he loosening dilapidat ion- land2 slide accumulation caused by forepart rainfall and the flood cau sed by act ivat ing rainfall are two init ial act i2 vat ing condit ions : the init ial act ivating substance condit ion and dynamic force condition. Therefore, the debr is flow
