| 英文摘要 | The present and future groundwater availability and exploitation were evaluated for an intermountain basin (Kohat Sub basin) of Northwest Himalayan Fold & thrust belt Pakistan by developing a 3D numerical groundwater flow model. The groundwater models attempt to represent an actual groundwater system with a mathematical counterpart. The conventional groundwater flow modeling procedure was followed to characterize complex hydrogeological system and predict future of fresh water resources in response to pumping and potential withdrawal. To support this study, geophysical, hydrological and metrological data of the entire basin including canals and river flow were used. The finite-difference groundwater modeling program (MODFLOW) was used for simulating the 3D groundwater flow in the region to investigate different water management strategies. The output is focused to predict the groundwater breed zone resulted in groundwater flow pattern, which closely resembled the natural flow. The hydraulic heads of the observation wells were used as initial conditions for steady state simulation; the model successfully generated heads calibrated with 95% confidence interval with correlation coefficient as 0.99. The model was also run for transient state which successfully generated the heads for the predicted year December, 2017. The groundwater withdrawal exceeding the annual recharge showed sudden drop of the water table by 25 meters, which demonstrated the future water deficiency. Continued withdrawal of groundwater and mismanagement showed possibility to lead critical condition on water availability. |
