A river that flows northwest through the western part of Ehime Prefecture. Its total length is 102 km. Its upper reaches are called the Uwa River, and it flows through the Ozu Basin, emptying into the Iyo Sea at Nagahama, northwest of Ozu City. Compared to the size of the river, there is little flat land, and even at the mouth of the river, there is almost no open alluvial lowland. Before land transportation developed, river boats traveled from the mouth of the river to Sakaishi (→Nomura), and it was also used for floating timber. The river basin was prone to flooding in the past, but in 1951 it was designated as a specific area for the comprehensive development of southwestern Shikoku, and in 1959 the Shikanogawa Dam was completed in Hijikawa Town and a levee was completed in the Ozu Basin, reducing flood damage. The Nomura Dam was completed in 1981. It is used for power generation and various water uses. The gravel in the riverbed is a good building material. Cormorant fishing in Ozu is famous. The area around Shikanogawa Lake belongs to Hijikawa Prefectural Natural Park.Hijikawa RiverSource: Encyclopaedia Britannica Concise Encyclopedia About Encyclopaedia Britannica Concise Encyclopedia Information |
愛媛県西部を北西に流れる川。全長 102km。上流を宇和川と称し,大洲盆地を流れ,大洲市北西の長浜で伊予灘に注ぐ。河川規模に比べて平地が少なく,河口部でも沖積低地がほとんど開けていない。陸運の発達するまでは河口から坂石 (→野村 ) まで川舟が通い,木材流しにも利用された。流域は古来洪水が多かったが,1951年四国西南総合開発特定地域に指定され,1959年肱川町に鹿野川ダム,大洲盆地に堤防が完成し,水害は減少した。 1981年に野村ダムが完成。発電,各種用水に利用。川床の砂利は良質な建築材。大洲の鵜飼いは有名。鹿野川湖周辺は肱川県立自然公園に属する。
