In this study, 'Toukaigata-3 Rivers' mean the rivers of the Fuji River, the Ohi River and the Tenryu River in Shizuoka Prefecture which have experienced floods many times in the historic times. For the developments of the plains in the lower courses of these rivers, there were a lot of gory struggles between floods and inhabitants without a break. In this study, the writer made researches in the floods on the plains of these rivers from a flood history point of view, and intended to make clear the characteristics of the floods in these rivers.According to the investigation on the floods since the beginning of the 16th century, the plains in the lower course of the Fuji River, the Ohi River and the Tenryu River suffered floods over 60, 130 and 100 times respectively. In the Fuji River, among those floods over 60 times, it became clear that there were very important two years holding the key to the solution of the questions of the flood history.One of them is the year which the huge embankments, 'Kariganezutsumi' were constructed along the left-hand side, by three generations of the father and child of Furugouri-Sigetaka, -Sigemasa and -Shigetoshi in 1674. Before this year, most of the floods flowed on the left-hand side plain, but after that, the floods were shifted to overflow on the right-band side plain. The other one was the year which the big earthquake, the so-called 'Ansei-Tokai-Jisin' , occurred in 1854. On the occasion of this earthquake, the active fault happened to occur along the riverbed from north to south, and the ground of the western side uplifted along the fault relatively. After that, the floods shifted again to the left-hand side plain, On the floods of the Fuji River and 'Toukaigata-3 Rivers, the writer has contributed a paper.

在这项研究中，“ Toukaigata-3河流”是指富士河的河流，Ohi河和Shizuoka县的Tenryu河，在历史时期经历了许多次洪水。对于这些河流下层课程中平原的发展，洪水和居民之间没有休息的洪水挣扎。在这项研究中，作者从洪水历史的角度从洪水泛滥的洪水进行了研究，并旨在清楚这些河流中洪水的特征。根据16世纪初以来对洪水的调查，自16世纪初，平原在富士河，Ohi River，Ohi River和Tenryu的较低的过程中遭受了600次及600次及600000000000000000年州的境地。在富士河中，在60次洪水中，很明显，两年来，有一个非常重要的是解决洪水历史问题的关键。其中一个是巨大的路堤“ Kariganezutsumi”，“ Kariganezutsumi”是在左侧建造的，这是Furugouri -sigetaka的父亲和儿童的左侧。洪水在左侧平原上流动，但在那之后，洪水被转移到右侧侧平原上的溢出。另一个是大地震，即所谓的“ Ansei-tokai-jisin”，发生在1854年。在发生地震之际，主动断层恰好发生在河床从北到南部，西部侧面的地面沿着断层相对较高。之后，洪水再次转移到左侧平原上，在富士河和'Toukaigata-3河流的洪水上，作家撰写了一篇论文。
