EtymologyEdit

The name comes from the Avestan Haētumant, literally "dammed, having a dam", which referred to the Helmand River and the irrigated areas around it.[2]

GeographyEdit

The Helmand River stretches for 1,150 km (710 mi). It rises in the Hindu Kush mountains, about 40 km[3] west of Kabul (34°34′N 68°33′E / 34.567°N 68.550°E / 34.567; 68.550), passing north of the Unai Pass, in the eastern proximities of Hazarajat, in Behsud, Maidan Wardak, flows west to Daykundi and Uruzgan. It crosses south-west through the desert of Dashti Margo, to the Sistan marshes and the Hamun-i-Helmand lake region around Zabol at the Afghan-Iranian border (31°9′N 61°33′E / 31.150°N 61.550°E / 31.150; 61.550). A few smaller rivers such as Tarnak and Arghandab  pour into Helmand.[4]

This river, managed by the Helmand and Arghandab Valley Authority is used extensively for irrigation, although a buildup of mineral salts has decreased its usefulness in watering crops. For much of its length, helmand is free of salt.[5] Its waters are essential for farmers in Afghanistan, but it feeds into Lake Hamun and is also important to farmers in Iran's southeastern Sistan and Baluchistan province.

A number of hydroelectric dams have created artificial reservoirs on some of the Afghanistan's rivers including the Kajakai on the Helmand River. The chief tributary of the Helmand river is the Arghandab River (confluence at 31°27′N 64°23′E / 31.450°N 64.383°E / 31.450; 64.383) which also has a major dam north of Kandahar.

HistoryEdit

The Helmand valley region is mentioned by name in the Avesta (Fargard 1:13) as the Aryan land of Haetumant, one of the early centres of the Zoroastrian faith in areas that are now Afghanistan. However, by the late first millennium BC and early first millennium AD, the preponderance of communities of Hindus and Buddhists in the Helmand and Kabul valleys led to Parthians referring to it as White-India.[6][7][8] [9]

As far as this place the land is under the rule of the Parthians.
