Abstract

<p> The July 2020 flood caused damage such as inundation of river water, inundation of landside water, scouring of river terrace, and damage to revetments in the section managed by the Ministry of Land, Infrastructure, Transport and Tourism of Gounokawa river. On the other hand, in the lower reaches of the Gounokawa river on the Shimane Prefecture side, the Ago district, where the residential land raising work has been completed, and the Yakami district (upstream block), where the levee is being developed, were protected from flood damage. This paper reports on the flood damage that occurred in Gounokawa river and the effects of hydraulic control work. In addition, we will introduce river basin management that is being promoted together with the Ministry of Land, Infrastructure, Transport and Tourism, prefectures, cities and towns.</p>
