Subsurface investigations in lower Palar river basin using vertical electrical resistivity surveys

摘要

Geophysical methods are widely employed all over the world due to its reliability and accuracy. Resistivity is one of the geophysical methods, which is indirect method in order to understand the formation characterization, so in this study also the same method has been followed. This study done on lower Palar basin, from where nineteen locations have been identified and VES has been conducted. The soundings are critically analysed using Auxiliary point chart method from which the resistance and thickness of each layer were found and it shows the formations are heterogeneity in nature
