ABSTRACT
Application of geophysical methods in groundwater investigations is based on identifying the anomalies caused by subsurface variations in physical properties and resolving hydrogeological conditions through subjective interpretations of the anomalies. A significant contrast in physical property and larger dimension of target (related to its depth) leading to an appreciable geophysical anomaly are required to resolve the target definition precisely. The efficacy of a geophysical method including instrumentation, data acquisition and interpretation lies in its ability to pick up anomalies due to small and deep targets with less-contrasting physical property and resolve them with least ambiguity.
