Hill-torrent floods are becoming a serious hazard owing to the changing climate in the arid region of
Pakistan. A large amount of floodwater is lost due to mismanagement, which results in the loss of valuable lives
and property downstream every year. In the present study, surface runoff potential was investigated and water
harvesting sites were identified for sustainable irrigation in the rod-kohi region of Dera Ismail Khan district of Khyber
Pakhtunkhwa province using GIS and RS techniques. Overall 533 water harvesting sites were identified with total
runoff potential of over 154 million m3
in the target hill-torrent region using geospatial modeling techniques coupled
with ground information. For water harvesting interventions, 26 sites were finally selected over the plain to gentle
slopes in unused land below 300 m elevation. Cost-effective earthen water reservoirs could be developed for future
runoff water harvesting in this region. An integrated floodwater management approach encompassing containment of
environmental degradation, institutional strengthening, and capacity building of the locals will have to be adopted for
the effective development of this region in the future.
