is a dam built on the Kisogawa River system, located in the Higashino section of Ena City, in Gifu Prefecture, Japan. ==History== The Agigawa (river) connects with the Kiso River just below Ōi Dam, running through a basin with a fairly large 2,000 mm of annual rainfall, and has long been used by Gifu Prefecture's Tōnō region (which includes the cities of Ena, Gifu, Ena and Nakutsugawa) for tap water and industrial-use water. However, in times of heavy rainfall, Agigawa River would quickly overflow, flooding the surrounding area. The river flows through Ena City, making levee construction difficult; the Chūō Expressway and the Central Japan Railway Company's Chūō Main Line also cross the river, which led to increased demand for safe flood control measures. Demand for tap water for Nagoya and the Chūkyō Metropolitan Area's postwar population boom, as well as industrial-use water for the Tōkai and Chūkyō Industrial Areas also rose. Attempts to meet water demand for Aichi Prefecture came up short, with the Makio Dam on the Ōtaki River alone proving insufficient. Water was also in short supply in Gifu Prefecture's Tōnō region, centering on Tajimi City, sometimes escalating to drought. Existing water rights and hydroelectricity-use water rights were given priority, precluding the possibility of siphoning off water from the middle of the river, and forcing the creation of multiple small reservoirs. With these problems in mind, the Ministry of Agriculture and Forestry (now the Ministry of Agriculture, Forestry and Fisheries) unveiled its plan to construct Agigawa Dam to—among other things—secure new water rights for irrigation of Gifu Prefecture's Tōnō region. In 1967, the project was passed along to the Ministry of Construction's Regional Developmental Bureau (now the Ministry of Land, Infrastructure, Transport and Tourism Chūbu Regional Developmental Bureau, and in 1969 the construction plans for a special multi-purpose dam were drafted. The Kisogawa had already been marked for water resource development following the Water Resources Development Promotion Act in 1966, but in March 1973 the "Kisogawa River Water System Development Plan " was partially amended, and the project was inherited by the Water Resources Development Public Corporation (now the (Incorporated Administrative) Japan Water Agency). With this, the construction of the multi-purpose Agigawa Dam continued, with the goal of leveraging both flood prevention and better water usage. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Agigawa Dam」の詳細全文を読む スポンサード リンク
