Abstract
Through the reconstruction of the Great East Japan Earthquake, the disaster waste treatment at the time of the large-scale disaster are taken up as a social problem. The abnormal weather which are pointed out to be related with global warming seems to be increasing and these weather has given serious damage to the region. A correct prediction of amount of disaster waste is important for quick and proper treatment and recycling. In this study, The examination of amount of regional material stock and disaster waste were carried out by using GIS. The disaster in Hidakagawa-cho(Wakayama) at the time of typhoon 12( 2011) was taken up as a case study. As the result of the examination, the following values were got, 97.2 Gg as material stock in the disaster area, 22.0 - 25.1 Gg as the predictive generating wastes and 0.2 - 0.7 as the collecting ratios. Although these values are not enough precision for practical use, it is considered that these data are effective for the further study of the development of the predictive method.
