Groundwater investigations in Pakistan: An emphasis on desert areas
The desert regions of Pakistan are located in all the four provinces and occupy a large area. The climate in deserts is very hot and dry. The annual rainfall is scanty (100-150 mm) and uncertain. The water-table varies from over 10 m in Cholistan to more than 100 m in Tharparkar. A programme for groundwater exploration in the desert areas of Pakistan was initiated in 1986. The exploration was carried out in selected parts of Cholistan (Punjab), Tharparkar and Nara (Sindh) and Winder in Balochistan Province. In the Cholistan desert (Punjab) a fresh groundwater body containing less than 1000 ppm of total dissolved solids in an area of about 1500 km2 has been discovered. The values of the coefficient of transmissivity and storage range from 120 to 1200 m2/day and 3.0 × 10-4 to 2.1 × 10-3respectively. In the Tharparkar desert (Sindh), an acceptable quality of groundwater containing up to 2500 ppm of total dissolved solids has been discovered in sandstone formation.
