Abstract
Geophysical survey is necessary to ascertain the subsurface geological and hydrogeological conditions. Various physical properties utilized in geophysical exploration include electrical conductivity, magnetic susceptibility, density, elasticity, and radioactivity. Depending upon the scale of operations, geophysical surveys can help delineate regional hydrogeological features or even pinpoint locations for drilling of boreholes. Geophysical surveys, though more expensive than hydrogeological investigations, can appreciably reduce much more costly drilling operations. Details of geophysical methods can be found in other standard texts (e.g. Dobrin, 1976; Parasnis, 1986; Telford et al., 1988). Geophysical applications specifically for groundwater are reviewed by a few workers (Zohdy et al., 1974; de Stadelhofen, 1994; Beeson and Jones, 1988; Palacky et al., 1981).
