Abstract

Water is an unlimited and exquisite gift which has been given by nature. However, its increasing demand and current pattern of usage are threats to human welfare, livelihood, development, and for the life itself, in the coming years. The main objective of this study was to quantify the ground water recharge due to rainfall on yearly basis of Peshawar district Khyber Pakhtunkhwa Province of Pakistan. Groundwater recharge was estimated by subtracting runoff from the rainfall. The Soil Conservation Service Curve Number (SCS-CN) method was used to estimate the runoff produced from rainfall events. As per the data provided by Pakistan Metrological Department, Peshawar, average annual rainfall in district Peshawar during 2002-2011 was 486.1 mm. The weighted curve number (CN) was found to  be 82.0. Mean annual runoff produced was estimated to be 217.0 mm where as mean annual recharge to the groundwater was calculated and found to be 269.1 mm. Different water conservation techniques are recommended to increase water recharge in the study area.
