Flood Control by Traditional River Technique in JapanIn Kumamoto Prefecture, there were many flood protection works such as diversion structures, levees and groynes made of stones which were constructed by Kiyomasa Kato as a feudal lord in the early Edo era. However, most works have not been clarified with actual proof as to how they play a role in flood protection. In this paper, Kutsuwa Domo commonly employed by Kiyomasa, which entails the widening a river at the confluence or rushing points to weaken floods, was investigated from the viewpoint of historical river regulation methods by applying a hydraulic model to a kutsuwa domo located at Shimada district in the Hamado river. The model scale was 1/150. The results of this paper showed that Kutsuwa domo was originally created by Kiyomasa, different from Kasumi bank (open levee) and effective works for floods exceeding the design limit.The Hanaguri channel is known for mysterious-shaped structures, which was constructed in the Nakasu mountain to irrigate a paddy field lying in the middle reach of the Shira river basin by Kiyomasa Katou in 1608.In this study, a field investigation and a model experiment were carried out to grasp the actual status and hydraulic functions of the Hanaguri channel. The results showed that the Hanaguri channel had 26 walls with a semicircular hole which was dug in the lower part of the wall, and the flow between the walls exhibited the characteristics of wall jet and had enough tractive force to transport volcanic ashes erupted from the Mt Aso.

日本传统河流技术防洪在熊本县，有许多防洪工程，如导流建筑物、堤坝和用石头制成的丁坝，这些都是江户时代早期由加藤清正作为封建领主建造的。然而，大多数工程都没有得到实际证明，说明它们如何在防洪中发挥作用。本文从历史河道整治方法的角度出发，对清泽县普遍采用的以拓宽汇合点或冲流点河道来减弱洪水的方法进行了研究，并将水工模型应用于滨多河岛田区的一处河床。模型比例尺为1/150。本文的研究结果表明，Kutsuwa Domo最初是由Kiyomasa创造的，不同于Kasumi堤岸(明堤)，它是应对超过设计极限的洪水的有效工程。1608年，Kiyomasa Katou在中须山修建了一座神秘的建筑物来灌溉石拉河流域中游的一片稻田，花仓水道以神秘的构筑物而闻名。结果表明，花古里海峡有26道墙，在墙的下部挖了一个半圆形的洞，墙之间的流动表现出墙喷流的特征，具有足够的牵引力来运输从麻生山喷发出来的火山灰。
