Khuzestan Province - Geography and Climate

Geography and Climate

The province of Khuzestan can be basically divided into two regions, the rolling hills and mountainous regions north of the Ahwaz Ridge, and the plains and marsh lands to its south. The area is irrigated by the Karoun, Karkheh, Jarahi and Maroun rivers. The northern section maintains a Persian (Lur, Bakhtiari, Khuzi) majority, while the southern section had an Arabic speaking majority until the great flood of job seekers from all over Iran inundated the oil and commerce centers on the coasts of the Persian Gulf since the 1940s. Presently, Khouzestan has several minority and ethnic groups of Lors-Bakhtiyaris-ghashghayee- Arabs and Persians from periods of history that Arabs were not mentioned anywhere.

Khuzestan has great potentials for agricultural expansion, which is almost unrivaled by the country's other provinces. Large and permanent rivers flow over the entire territory contributing to the fertility of the land. Karun, Iran's most effluent river, 850 kilometers long, flows into the Persian Gulf through this province. The agricultural potential of most of these rivers, however, and particularly in their lower reaches, is hampered by the fact that their waters carry salt, the amount of which increases as the rivers flow away from the source mountains and hills. In case of the Karun, a single tributary river, Rud-i Shur ("Salty River") that flows into the Karun above Shushtar contributes most of the salt that the river carries. As such, the freshness of the Karun waters can be greatly enhanced if the Rud-i Shur could be diverted away from the Karun. The same applies to the Jarahi and Karkheh in their lower reaches. Only the Marun is exempt from this.

The climate of Khuzestan is generally hot and occasionally humid, particularly in the south, while winters are much more pleasant and dry. Summertime temperatures routinely exceed 50 degrees Celsius and in the winter it can drop below freezing, with occasional snowfall, all the way south to Ahwaz. Khuzestan province is known to master the hottest temperatures on record for a populated city anywhere in the world. Many sandstorms and duststorms are frequent with the arid and desert-style terrains.
