The Wachandarja (also written Wachan or Wakhan or called Wak ; Tajik Вахондарё Wachondarjo ; Russian Вахандарья ) is the left headwaters of the Pandsch in Central Asia .
River course
The river arises in the border area of the Hindu Kush and Pamir mountains in the Badachschan province in the extreme northeast of Afghanistan near Baza'i Gonbad at an altitude of around 3885 m from the union of two mountain rivers:
- The smaller one on the right has its source in ice fields at around 4900 m above sea level and initially flows southwest. When entering the broad high mountain valley of the Wachan corridor, which runs to the west-east, it forks in a large alluvial cone . The left branch flows over the moraine reservoir Shaqmaqtin into the northeast flowing Aksu . The right arm flows in the opposite direction as a wachan . However, both do not drain into different seas, but meet again at the confluence of the Bartang and Pandsch rivers.
- The larger left source river is formed from the melt waters of several glaciers near the Wakhjir Pass , which are framed by mountain ranges up to almost 6000 m high and flows in an elongated course through a high mountain valley lined with extensive moraines of late Ice Age glaciers.
Together with this main spring river, the Wachan has a length of 220 kilometers. Then it joins southeast of the 6,726 m high Karl Marx peak near the border with Tajikistan near the village of Langar at an altitude of 2,799 m with the Pamir to the Pandsch .
A hydropower plant was built near Langar, which is already in Tajikistan in a narrow valley between the Hindu Kush and the Pamirs .
