In this study, an estimation procedure was established to assess the amount of debris resulting from earthquake and flood disasters. Per unit generation of earthquake disaster debris was examined on the basis of observed debris discharge from the 1995 Great Hanshin Awaji Earthquake and the 2004 Niigata Chuetsu Earthquake. In addition, the per unit generation of disaster debris from flood damage above floor level was estimated at 4.6 t/household. It was shown that this procedure would allow the amount of debris to be estimated in order that disaster management and operation systems could be established for not only emergency response in the aftermath, but also pre-disaster planning. In a case study, the amount of disaster debris from earthquake and catastrophic flood disasters in the Tokyo Metropolitan Area was estimated according to hazard maps. It is concluded that it is important, from the viewpoint of the security of sanitary systems in the damaged district, that disaster debris management systems including wide-ranging cooperative measures should be established.
