Abstract
We had a deluge in July 2012 in the northern Kyushu district with intense rainfall of 800mm and 108mm/hr. This intensity yielded countless traces of debris flow and slope failures that induced tremendous damage and causalities in the area. Hence, several field investigations and reconnaissance tasks were conducted by the society to delve into this sediment]related disaster. The various results and the information obtained through this investigation were reported as the primary report, mentioning the damage, geologic]geomorphologic features and hydraulic characteristics of the debris flows, vegetation effects, and the efficiency of Sabo facilities in other scenes of this disaster.
