项目摘要

1. Research report on Hiroshima disaster due to the torrential downpour :The main cause of the Hiroshima disaster is that the heavy rain due to the cold front continued for 2 or 3 hours at the Masa soil belts. This heavy rain appeared in the band with small width. It was considered that this concentration of rainfall was under the influence of the mountainous geographical features. A radar rain gauge was effective for tracing the movement of the heavy rain. The danger of the disaster can be predicted by analyzing the amount of the ground water from precipitation.Geology structure, geographical features and formation of micro seating are given as a cause of disaster except for rain. The mud-flow with the driftwood, which didn't contain large rocks, brought. The debris flow can be expressed by Egashira's model. The hazard maps and the effects on countermeasures can be examined by using this models.The inhabitants don't run away only with the advanced information such as a rainfall. The i … More nhabitants run away by the confirmation of the mud water and the slope collapse, and the refuge advice. Therefore, it becomes important for reducing the sudden disasters that information is transmitted precisely and quickly when the disaster occurs and the consciousness for disaster prevention of inhabitants is raised.2. Research report on the urban flood damage in Fukuoka CityThe heavy rain in north area of Kyushu is due to rain band around the cold front. The water level of the Mikasa River was raised due to the high tide of Hakata bay and a heavy rain, and the Mikasa River overflowed. The damage due to inundation occurred around JR Hakata station whose ground was low. Flooding water got into the underground space around JR Hakata station. The late person who ran away died. It is effective in prevention of an overflowing water invasion underground to use the sand bugs and raise an entrance more than the passage side. The transmission of the the command system are necessary for the precise information.The cause of this disaster was that the high tide of Hakata bay occurred at the same time for a heavy rain and the amount of discharge increased due to the urbanization. The establishment to prevent an overflowing water invasion, the information transmission to underground, the disaster consciousness improvement are necessary except for river improvements to reduce the new urban flood damage.

1。关于倾盆大雨造成的广岛灾难的研究报告：广岛灾难的主要原因是，由于寒冷阵线造成的大雨持续了2或3个小时。这场大雨在乐队中出现，宽度很小。据认为，这种降雨集中在山区地理特征的影响下。雷达雨量表对于追踪大雨的运动有效。可以通过分析降水量的地下水数量来预测灾难的危险。地质结构，地理特征和微观座位的形成是作为灾难的原因，除了雨水。带有不包含大石头的浮木的泥流。碎屑流可以通过Egashira的模型表示。可以通过使用此模型来检查危险图和对对策的影响。居民不仅可以逃离诸如降雨之类的先进信息。我……更多的小ob虫因确认泥水和斜坡倒塌以及避难所的建议而逃跑。因此，对于减少突然的灾难而言，当灾难发生时，信息会精确而迅速地传播，并且提出了预防居民灾难的意识。2。福库卡市城市洪水破坏的研究报告，九州北部地区的大雨是由于寒冷阵线周围的雨带。 Mikasa河的水位是由于Hakata湾的高潮和大雨而升起的，Mikasa河泛滥成灾。淹没造成的损害发生在JR Hakata车站周围的地面很低。洪水进入JR Hakata车站周围的地下空间。逃跑的已故人死了。它可以有效预防地下水入侵溢出，以使用沙虫，并抬起入口比通道侧更多。指挥系统的传播是确切信息所必需的。这场灾难的原因是，哈卡塔湾的高潮同时发生了大雨，由于城市化而导致的排放量增加。为了防止水入侵，向地下的信息传播，灾难意识的改善是必要的，除了河流改善以减少新的城市洪水破坏，这是必要的。较少的
