To achieve the objectives of the study, a parsimonious working surface-groundwater interaction groundwater flow model, using MODFLOW Package, was developed for understanding the hydro-geological dynamics under different aquifer management interventions as part of climate responsive policy. The developed model was calibrated using PEST (acronym for Parameter ESTimation) Package. There was a close agreement between the observed and simulated heads and the overall trend of the observed groundwater hydrograph was also followed well by the modelled data.The impact of climate change was investigated by considering ten future scenarios divided under two broad conditions: (i) future population growth rate ranging from 2.5 to 2.2%; and (ii) total population restricted at the level of last calibrationperiod (2000 “ 2004). The results of all the future scenarios indicate that the aquifer storage underneath Lahore and surrounding areas will continue to decrease with the passage of time under different weather conditions. Due to heavy abstraction rates, the developed cones of depression will widen over time and space. Formation of sink conditions will result in flow of groundwater from semi-urban/rural areas of Lahore towards the urban area.
