Abstract :

Water is most important for sustenance of life on planet Earth. The utilization of water has increased due population explosion. It has become essential to increase the productivity of groundwater for human needs. As more areas are being exploited for groundwater several problems arise due to complex geology of the area and seepage into the subsurface. Seawater intrusion is a major factor that affects groundwater quality. It occurs when withdrawal of fresh groundwater from coastal aquifers results in declining groundwater levels, facilitating lateral and/or vertical migration of saline water causing deterioration of groundwater quality. Electrical resistivity sounding techniques and are widely used to determine the intrusion zones between groundwater and saline water in coastal aquifers. In the present paper we have made an attempt to delineate fresh water horizons in the Kelwa–Mine Beach coastal region of western Maharashtra. In order to delineate the fresh water zones using geophysical techniques 53 Vertical Electrical Soundings were carried out at the site. The present investigation presents the importance of VES in delineating saline water–fresh water zones.
