Salinity Assessment and Mapping Using Remote Sensing and GIS Technique in Gurugram District, Haryana

Abstract

Electrical Conductivity (EC) and Total Dissolved Solids (TDS) are the two methods most frequently used for measurement of salt in water. In present study EC of water has been used for analysis of salt. Groundwater samples were collected from the Gurugram district of Haryana (India) in summer before the monsoon and after the monsoon season. It was observed that 22 sampling sites in summer before the monsoon and 23 sampling sites after the monsoon season were of 'Low' class having EC under 1500 Micromhos/cm. Based on observed data and using geoinformatics, EC map has been prepared for Gurugram district. This study will be very useful for policymakers, farmers and local public. Using EC map salt concentration of groundwater can be easily visualized without any technical knowledge and study can be extended for other areas.
