Abstract This study provides an estimate of fresh water derived from ice melt for the ablation areas glaciers in Central Karakoram National Park (CKNP), Pakistan. In CKNP there are ~700 glaciers, covering ~4600 km 2 , with widespread debris cover (518 ). To assess meltwater volume we applied a distributed model able to describe both debris-covered and debris-free ablation. The was calibrated using data collected field area validated by comparison field, independent used building model. During 23 July–9 August 2011, mean model-estimated 0.024 m w.e. d –1 0.037 areas. We found error +0.01 (corresponding 2%) root-mean-square equal 0.09 (17%). According our model, all produced 1.963 3 during period. Finally, performed several sensitivity tests assessing impact input variations.
