Basically, the province of Khuzestan can be divided into two regions, the plains and mountainous regions. The agricultural lands are fertile and mainly in the west of the province, which are irrigated by the Karun, Karkheh and Jarahi rivers. These three large and permanent rivers flow over the entire territory contributing to the fertility of the land. Karun, Iran’s largest river, 850 kilometers long, flows into the Persian Gulf through this province.
