Other Abstract



The formation and evolvement process of this debris flow was analyzed based on the field investigation on the material sources, rainfall, and topography conditions. The rainfall was the inducing factor; however, the topography in the gully was the main reason which causes this catastrophic debris flow: (1) the dammed lakes formed in the earthquake were broken which increased the water supply, strengthened the dynamic force, and aggravated the erosion quantity finally. (2) the narrow sections and the drops amplified thepeak flow and velocity of the debris flow in the gully. (3) the solid material supplies the debris flow and enlarged the density along thegully. The possibility and frequency of debris flow will be much higher in heavy rainfalls in the future, but the scale will be less than thisgiant debris flow because of the microtopography had been changing. Suggestions were proposed: the warning system, control engineering should be built and disaster prevention and reduction awareness of local people also should be improved.
