Arghandab River

The Arghandab is a river in Afghanistan, about 400 km (250 mi) in length. It rises in Ghazni Province, west of the city of Ghazni, and flows southwest, passing near the city of Kandahar, before joining the Helmand River 30 km (19 mi) below the town of Grishk. 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 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.
