A basin developed in the middle reaches of the Hiji River in western Ehime Prefecture. Its area is approximately 10 square kilometers. The basin floor is low, at 10 to 15 meters above sea level, and is located 15 to 20 kilometers from the river mouth. The Hiji River narrows downstream and becomes a leading river, causing flood damage every time there is heavy rain. It has been a plague since the feudal era, but the damage has decreased with the completion of the Kanogawa Dam and bank protection work. Radiation fog occurs from autumn to winter, resulting in little sunshine. In addition to rice paddies, mulberry and tea cultivation is thriving.

愛媛県西部、肱(ひじ)川の中流域に発達した盆地。面積約10平方キロメートル。盆地床の標高は10~15メートルで低く、河口から15~20キロメートルの距離にある。肱川は下流で狭隘(きょうあい)となり、先行性河川となるので、豪雨のたびに湛水(たんすい)し、洪水被害をもたらした。藩政時代から苦しめられたが、鹿野川(かのがわ)ダムの完成や護岸工事などによって被害は減少した。秋から冬にかけ放射霧が発生し、寡照となる。水田のほか桑や茶の栽培が盛ん。 [深石一夫] 愛媛県大洲市©一般社団法人愛媛県観光物産協会"> 鹿野川ダム 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
