River channels tend to modify and migrate due to both anthropogenic influences and continuous natural changes in environment, so can be subsequently lead to catastrophic effects in case of floods. With the improvements in geospatial analysis and availability of massive dataset it is possible to study fluvial regimes in detail. Aim of this research was to identify potential migration river channel zones and to assess the degree of evolution in past two decades. Features analyzed, to assess evolution, were River width, braid-channel ratio, river sinuosity and riparian vegetation. River migration zones were identified based on data from 1990 to 2010 and it was found that substantial potential river migration zones are at Indus river in Rajanpur district, Chenab river in Muzzafargarh and Jhang districts ,moderate potential migrating zones are at Indus river (in some zones of Rajanpur, DG Khan and Mianwali), Chenab river (in some parts of Jhang and Muzaffargarh), Jhelum river (in Jehlum and Khoshab), Ravi river (at end of Lahore), and Sutlej river (near Pakpattan and Vehari districts) while all other zones were observed to be falling in least potential migration zones. In most potential migration zones, further calculated attributes, that were river width, braids-channel ratio, river sinuosity and riparian vegetation, were found to be undergone through change at much impressive rates than other zones. Understating river’s response in channel migration is essential to set reliable targets for restoration efforts.
