The main purpose of the present study is to describe the disaster occured in Tokai region due to heavy rainfall at September 11 and 12, 2001. The results have been summarized as below :・ The mechanism of the heavy rainfall has been clarified from meteorological point of view.・ The hydrological statistics has been analyzed in order to compare the magnitude of the designed rainfall and that of the observed one.・ Flooding and inundation in urban areas have been described using both hydrodynamic model and field survey for marks of inundation, which has made it possible to discuss the problems in the disaster.・ It is confirmed that the complex system for flood protection that consists of a main river, tributaries and drainage of inner basin causes many problems among all people living in the basin.・ The mechanism of the levee breach at Shin-kawa has been clarified with the analysis based on soil mechanics.・ The functional disorder in underground spaces during the disaster has been investiga … More ted. The method to prevent it has also been discussed.・ The functional disorder of transportation system during the disaster has been summarized. The use of I.T.for preventing it has been proposed.・ The transfer of disaster information among people and evacuation activities has been checked through the number of hearing survey to the people living in the basin. The proper crisis management has also been discussed.・ The actual conditions of the refuge site, the reconstruction and the waste produced by the disaster have been investigated.・ The actual condition of the levee breach occurred in several small rivers in Aich prefecture and consequent flooding have been summarized.・ The production of sediment and woody debris in upper reach of the Yahagi river and resulting disaster along the channel have been investigated.・ The response of the people to the suddenly increased destructive discharge that occurred downstream of the Yahagi dam due to the gate opening has been investigated to discuss the proper crisis management.・ The aforementioned disasters have been classified based on both the regional characteristics and the problem of the disaster. The lesson we got through the disaster has been summarized finally. Less

本研究的主要目的是描述2001年9月11日和12日发生在东海地区的暴雨灾害。结果表明：·从气象学角度阐明了这次暴雨的形成机制。为了比较设计降雨量和观测降雨量，对水文统计数据进行了分析。·本文用水动力学模型和淹没标志的实地调查两种方法描述了城市的洪水和淹没，从而使讨论灾害中的问题成为可能。确认了由一条主要河流、支流和流域内的排水系统组成的复杂防洪系统给生活在流域内的所有人带来了许多问题。通过土力学分析，阐明了新川大堤溃决的机理。·地下空间在灾害中的功能紊乱已引起人们的关注， ...更多信息 Ted.同时也讨论了预防的方法。·总结了交通系统在灾害中的功能紊乱。有人建议使用信息技术来预防这种情况。·通过对居住在流域内的人们进行听力调查，检查了人们之间的灾害信息传递和疏散活动。还讨论了适当的危机管理。·对避难场所的实际情况、重建情况和灾害产生的废弃物进行了调查。·总结了艾希地区几条小河发生决堤和洪水泛滥的实际情况。调查了矢贺木河上游泥沙和木质残体的产生及其造成的沿着灾害。人们对雅哈吉大坝下游因闸门开启而突然增加的破坏性流量的反应进行了调查，以讨论适当的危机管理。·上述灾害是根据区域特点和灾害问题进行分类的。最后总结了这次灾难给我们的教训。少
