Groundwater Detection using Electrical Resistivity Technique in Fort Abbas, District Bhawalnagar, Punjab, Pakistan (P-1182) (MFN 5841)

Abstract

A total of 03 observation points were done in the Fort Abbas, District Bahawalnagar, Punjab. The details of field survey conducted, methodology, analysis of the data collected, results and recommendations are presented in this dissertation. Survey is conducted for detection of groundwater using electrical resistivity technique. Survey was conducted by using four electrodes, stiffly mounted in the ground for measuring of potential drop between two of the electrodes (potential electrodes). Values of resistivity obtained is apparent resistivity which later gives us true resistivity values. At the end resistivity values are plotted on map through computer software IPI2Win, to generate a resistivity curve that helps us in interpretation of subsurface strata. Lithological columns were also made in practice to get knowledge about what is the picture of subsurface lithology and where did fresh water and saline water encountered. Fresh water zones were selected at the end and then we proposed which site is most suitable for tube well installation.
