Aerial view of Arghandab River ارغنداب رود Afghanistan

Aerial view of Arghandab River ارغنداب رود Afghanistan Arghandab is a river in Afghanistan, about 400 km (250 mi) in length. It rises in the Hazarajat country north-west of Ghazni, flows south-west passing near the city of Kandahar, and then falls into the Helmand 30 km (19 mi) below Girishk. In its lower course it is much used for irrigation, under the control of the Helmand and Arghandab Valley Authority, and the valley is cultivated and populous; yet the water is said to be somewhat brackish. It is doubtful whether the ancient Arachotus is to be identified with the Arghandab or with its chief confluent the Tarnak, which joins it on the left 50 km (31 mi) southwest of Kandahar. The Tarnak, which flows south of Kandahar, is much shorter (length about 320 km or 200 miles) and less copious.
