**2. The study region**

Geographically, Eastern Hindu Kush in Pakistan extends between 34° 34̍11̋to 36° 54̍30̋North Latitude and 71°11̍56̋to 73°52̍5̋East Longitude. Hindu Kush region lies in the west of Himalayas. Its western section falls in Afghanistan, however the eastern section located in Pakistan. The drainage basins of river Swat and Chitral are covering the eastern section of Hindu Kush mountain system. Swat River originates from two major glaciers of Ushu and Gabral, whereas river Chitral originates from Chiantar glacier. The study region is famous for its beautiful and fertile river valleys, which support large population (**Figure 1**) [14].

Eastern Hindu Kush stretches from Karambar Pass in East to the Dorah Pas not far from Mount Tirch Mir. The Central part continues to the Shebar Pass to the northwest of Kabul. The Western part of Hindu Kush descends to the Kermu Pass. In the extreme eastern region between the Karambar and Baroghil is dominated by very high peaks. Administratively, the Eastern Hindu Kush consists of the following districts, District of Chitral, Upper Dir, Lower Dir and Swat Scott [15]. The region is prone to heavy rainfall, surface runoff and flash floods which further intensity soil loss [16, 17].
