Tarnak River Explained

The Tarnak River is located in Ghazni, Zabul, and Kandahar provinces of Afghanistan. The city of Kandahar is located on a plain directly adjacent to the Tarnak.^[1]

It rises in Afghanistan's highlands region of Hazarajat, near 33.1167°N 123°W, south of the Lomar Pass. The Tarnak flows in a south-westerly direction for around 350 km before joining the Dori River some 30 km downstream of the Dori-Arghastan confluence, and some 30 km upstream of the Dori-Arghandab confluence, at 31.4°N 98°W.^[2] The combined waters of these rivers join the Helmand at 31.45°N 87°W, near Lashkargah.^[3]

Geography

The Tarnak River valley is a tectonic trough that runs from northeast to southwest. It has multilayered aquifers and both Quaternary and Neocene deposits.^[4]
