Kunar River

The Kūnaṛ River (د کونړ سيند; ; کونڑ سيند), also known as the Chitral River (دریائے چترال), Mastuj River (مستوج سيند) and Kaama River (کامې سيند), is a 480 km long river in northern Pakistan and eastern Afghanistan. It originates just south of the Broghil Pass, in the Upper Chitral District of Khyber Pakhtunkhwa province in Pakistan. It later merges with Kabul river in the Nangahar Province of Afghanistan. The river system is fed by melting glaciers and snow of the Hindu Kush mountains. The Kunar River is a tributary of the Kabul river, which is in turn a tributary of the Indus River.

Origin and course of flow
The river rises in the far north glaciated Hindu Kush mountains of Chitral, Pakistan, where it is referred to as Chitral river. Around 60% to 70% of annual discharge of Kunar river originates from Chitral. Downstream as far as the town of Mastuj, it is called as the Mastuj river, till its confluence with the Lotkoh river. Kunar then turns southwards into the upper Kunar Valley of Afghanistan. At the confluence in Asadabad, it meets with Pech River and finally empties into the Kabul River just to the east of the city of Jalalabad in Afghanistan. The combined rivers then flow eastwards into Pakistan again, and joins the Indus River at the city of Attock.
