The largest river in Irian Jaya, in the western half of New Guinea, Indonesia. It originates near Mount Mandara (formerly known as Mount Juliana) in the Central Mountain Range, flows south through large marshes, then turns west and meanders before emptying into the Arafura Sea. It is approximately 800 km long. The river's mouth was discovered by the Dutch Navy in 1903, and exploration of the basin took place between 1905 and 1909. The river is 6 km wide at its mouth, and with its abundant water, it is navigable quite upstream. However, the downstream basin is a marshland covered in dense forest, and is extremely sparsely populated. [Bessagi Atsuhiko] Source: Heibonsha World Encyclopedia, 2nd Edition Information |
インドネシア,ニューギニア島西半部のイリアン・ジャヤ最大の川。中央山脈のマンダラ山(旧名ユリアナ峰)付近に発源,大湿原を南下して西に方向を転じ,蛇行しつつアラフラ海に注ぐ。延長約800km。河口が1903年オランダ海軍に発見され,05‐09年に流域の探検が行われた。川幅は河口で6kmもあり,水量も豊かなのでかなり上流まで航行できる。しかし下流の流域は密林に覆われた湿原で,人口はきわめて希薄である。【別技 篤彦】
