Determination the Effects of Khanpur Dam Reservoir on Nutrition Source of Groundwater

Mohammad Saleem Khan, Sajid Rashid Ahmad, Muhammad Mushtaq and Ghulam Muhammad    

Abstract: The groundwater has unique importance as protected nutrition source for survival of sustainable life against the growing surface water contamination. Groundwater receives its recharge from surface water as a part of hydrologic cycle but due to filtration process through various layers remains protected. However the water in the unconfined aquifer is more quickly influenced and gets contaminated due to industrial and other anthropogenic activities. The extra ordinary recharge from dams located at elevation is capable to induce water logging conditions in the downstream areas. The investigation in the Dhamrah Kas Basin shows that the groundwater fluctuations are being controlled by the reservoir filling and depletion in the Khanpur dam. As a result the water table is forced to fluctuate between elevations of 1640 to 1670 feet. The maximum rise of 42 feet has been recorded since the construction of Khanpur Dam during 1983. Hence due to the rise of water table the probability of groundwater contamination has been increased many folds. However stagnancy trend in the water table since 1992 reveals sealing of discontinuities due to sedimentation, so there are no chances of water logging due to Khanpur dam in the study area.
