Abstract

 Contradictory approaches to water sharing at regional and global scale has detrimental impacts on human (domestic and agricultural) and ecological demands. Economic activities have also been affected, where reliance of survival is on agriculture. This study focuses on past and future flow trends and water availability in Jhelum basin (River Neelum). Neelum River is largest tributary if Jhelum basin and also important due to its transboundary distribution nature. To detect historical trends of flow data, the Man Kendall and Sen’s slope trend analysis has been carried out, whereas the future projections in the flow regime has been estimated using Morkove stationary method. The analysis shows significant flow depreciation in last two and half decades (1991-2013). The annual average declining rate is 3.386 m3/s per year and monthly is ranging between 16.915 m3/s to 0.214 m3/s per year at Nusheri (significant decline in Jun, July and August) station and at Muzaffarabad station (downstream to Nusheri) the annual average decline rate is 3.186 m3/s while monthly ranging between 13.198 m3/s to 0.23 m3/s per year (significant decline in Jun, July and August). The overall flow depreciation is estimated 14% by volume at both stations. Both countries have built (Kishan Ganga and Neelum Jhelum) hydropower projects therefore, fair allocation of flow without curtailing water will be an endurance and resilience withstanding of jolts of Pak-India turbulent relations.
