新潟平野の本格的な治水の変遷は,近世中期の松ケ崎放水路の開削に始まり,治水技術の近代化を待って,大河津分水の完成をもって一応の完結をみた.その近代的治水技術の中心となったものは土工機械力,近代的堰・水門及びポンプであった.これら近代技術の登場によって,洪水時や平水時にかかわらず自由な流水のコントロールが可能となった.この新技術は明治後期の日本人技術者達の試行錯誤の上に成立つものであった.Development of flood controls in the Niigata Plain began from the excavation of the Matsugasaki Floodway in 1731, the mid-Tokugawa era. After modernization of flood control techniques, this development was completed, for the time being, through the accomplishment of the Okozu floodway in 1931. This modern flood control techniques mainly cover weirs, gates, and the use of pumps, modern construction equipment and methods. By using these modern techniques, river flow can easily be controlled in spite of large flood. This new technology had been devised through trial and error by Japanese engineers in the latter Meiji era. Hence, we can trace the development of flood control techniques in Japan through a research on the history of flood controls in the Niigata Plain.
