Study on Disaster caused by Heavy rainfall in Tokai Region, Japan at September 2001

目前研究的主要目标是描述2001年9月11日和12日在东京地区发生的灾害，并将发生严重的降雨。结果被归纳为以下：“沉重的雨水的机制已经从气象学的角度清晰可见。”水力统计数据已被分析，以比较所设计的雨水的强度，以及观察到的雨水的强度。在城市地区的洪水和灌溉已经被描述为使用氢动力模型和实地调查来进行灌溉的标记，这是有可能解决灾难中的问题的。它证实了洪水保护的复杂系统，它是指主要河流、树木和排水的因素，导致了所有人生活在盆地的内部盆地中的许多问题。Shin-Kawa对Levee破裂的机理已经被界定为基于土壤机理的分析。地下空间中的功能性紊乱-在调查期间，灾难发生了 ...

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
