Karun River
Karun River (Persian Kuran), a Persian river of some importance, rises near Ispahan and, flowing first west, takes a southerly direction just above Shuster, and empties itself into the Persian Gulf a few miles to the east of the mouth of the Tigris. It has a total course of about 300 miles., but is navigable only for about two-thirds of its length, and at Ahwaz rapids impede navigation even within the navigable distance. The importance of the river as a channel for trade was pointed out so early as 1842, but it was only in 1888 that, in consequence of the representations of Sir H. D. Wolff, the Karun was thrown open to the vessels of all countries by royal proclamation.
