A large river that runs through the central United States from north to south. It is the fourth largest river in the world, with a total length of 5,969 km from the source of its longest tributary, the Missouri River. The main stream begins in northern Minnesota and flows south to the Gulf of Mexico. Its drainage area is about 3.25 million km2 , accounting for about 40% of the entire United States. In addition to the Missouri River, other major tributaries include the Arkansas River, Red River, Illinois River, and Ohio River. It is used on a large scale for water transportation, power generation, irrigation, and water supply. The French, who first settled in the basin, recognized the importance of the river and named the basin Louisiana in 1682. In 1718, they founded New Orleans at the mouth of the river. The entire basin became U.S. territory with the Louisiana Purchase in 1803. The heyday of river traffic was around the time of the Civil War, but even today it is possible to travel up the river by steamship to Minneapolis, making it a major inland artery. It has been the setting for many literary works, including Mark Twain's "The Adventures of Tom Sawyer" and "The Adventures of Huckleberry Finn." → Related articles Arkansas [River] | De Soto Source : Heibonsha Encyclopedia About MyPedia Information |
米国中央部を北部から南部に貫流する大河。最長の支流ミズーリ川の源流からは全長5969kmで世界第4の大河。本流はミネソタ州北部に発し南下してメキシコ湾に注ぐ。流域面積約325万km2で,米国全土の約40%に達する。主要な支流はミズーリ川のほかに,アーカンソー川,レッド川,イリノイ川,オハイオ川など。水運・発電・灌漑(かんがい)・用水など大規模に利用される。流域に最初来住したフランス人はこの川の重要性を認め,1682年流域をルイジアナと命名,1718年には河口にニューオーリンズを創建した。1803年ルイジアナ購入により全流域が米国領となった。河川交通の最盛期は南北戦争ころまでであるが,現在でもミネアポリスまで汽船の遡航(そこう)が可能で内陸の大きな動脈である。マーク・トウェーンの《トム・ソーヤーの冒険》,《ハックルベリー・フィンの冒険》をはじめ多くの文学作品の舞台となっている。 →関連項目アーカンソー[川]|デ・ソト 出典 株式会社平凡社百科事典マイペディアについて 情報 |
