Assessment of the Climatic Variability of the Kunhar River Basin, Pakistan

Pakistan is water stressed, and its resources are vulnerable due to uncertain climatic changes. Uncertainties inherent when it comes the modeling of resources. The predicted flow variation in Kunhar River Basin was modeled using statistically decreased high-resolution general circulation model (GCM) as an input for Hydrologiska Byråns Vattenbalansavdelning (HBV) assess hydrological response under prevailing climate model’s best performance during calibration validation stages obtained with a regular 0.87 0.79 Nash–Sutcliffe efficiency basin, respectively. Under high-end emission scenario, 122% increase expected evapotranspiration rising season months winter period 2059–2079, such developments were attributed immense liquid precipitation temperature. output reflects potential basin stream terms increasing up 182% at beginning monsoon 2059–2079 scenario emissions. Moreover, study produced possible uncertainties high-elevation zones, where catchment can lead typical snow ablation accumulation future projections. This revealed that rate will annually, resulting summer over though hardly accumulate basin’s climate.
