“…Most of these methods require analysis of a large volume of hydrological data (precipitation, surface runoff, evapotranspiration, change in groundwater storage, etc.) accumulated over a considerable time span, which is inadequate or unreliable in many areas (Chand et al, 2004). An advantage of tracer techniques for recharge estimation (Zimmermann et al, 1966(Zimmermann et al, , 1967Dincer et al, 1974;Athavale et al, 1980;Athavale and Rangarajan, 1988;Wood and Sanford, 1995;Sukhija et al, 1996;Rangarajan and Athavale, 2000;Chand et al, 2004) is that the requirements are often for shorter-term and more easily obtained data.…”

“…There have been many studies investigating the aquifer parameters from geophysical method in order to support essential input to groundwater flow model (Kelley, 1977;Mazac et al, 1985;Huntley, 1986;Frohlich et al, 1996;Singhal et al 1998;Niwas and de Lima, 2003;Chand et al, 2004;Singh, 2005;Chandra, 2006 andChandra et al, 2008). Thus the 2D/3D resisitivity distribution of the geological discontinuities is useful parameter to characterizes the hydrodynamic properties of the hard rock system.…”

“…rainfall) and, to a minor extent, infiltration of water from the ponds and surface water applications. Groundwater occurs in the fractures, joints, fissures and weathered zones of the basement rock below the water table, under semi-confined conditions (Chand et al 2004). Joints and fractures have also been recorded at depths below 10 m. These weaker zones/planes might act as major conduits for groundwater flow.…”

An integrated study was carried out to investigate the subsurface geological conditions in a hard rock environment, with the aim of identifying zones with groundwater resource potential. The study, in Bairasagara watershed, Karnataka, India, considered geomorphology, water level, resistivity imaging, self potential, total magnetic field and susceptibility. The signatures due to lineaments have been clearly identified and their role in groundwater movement has been documented. Synthetic simulation methods were used to model the electrical response of the lineament using finite differential modeling scheme. The inverted image of the field data is compared with the synthetic image and iteration were performed on the initial model until a best match was obtained resulting on the generation of the calibrated resistivity image of the subsurface. Resistivity imaging revealed that the dykes are weathered/fractured to a depth of 6-8 m and are compact at deeper levels, and that they behave as barriers to groundwater movement, yet facilitate a good groundwater potential zone on the upgra- dient side. The results of magnetic surveys were utilized in differentiating granites and dolerite dykes with an insignificant resistivity contrast. Geomorphological expression alone cannot reveal the groundwater potential associated with a lineament. However, characterizing the nature of the feature at depth with integrated geophysical methods provides essential information for assessing that potential.Résumé Uneétude aété réalisée sur la géologique de sub-surface en milieu rocheux fracturé, avec pour objectif l'identification des zones possédant des potentiels de ressource en eau souterraine. Cetteétude, sur le bassin versant de Bairasagara, Karnataka, prend en compte la géomorphologie, le niveau de l'eau, les images de résistivité, le self potentiel, le champ magnétique total et la susceptibilité. Les signaux dusà la présence de linéaments, ontété clairement identifiés ainsi que leur influence sur le mouvement des eaux souterraines. Les méthodes de simulation synthétique ontété utilisées pour modéliser la réponsé electrique des linéaments, en utilisant une modélisation par différences finies. L'image inversée des données de terrain est comparée avec l'image synthétique; des itérations sur le modèle initial ontété mises en oeuvre jusqu'à un rapprochement optimal, résultant en la génération d'une image calibrée de la résistivité de la sub-surface. Les images de résistivités révèlent que les dykes sont altérés et fracturés sur une profondeur de 6à 8 mètres et sont compactésà des profondeurs plus importantes. Les dykes se conduisent dés lors comme des barrières au mouvement des eaux souterraines. Cependant ils favorisent un bon potentiel, du point de vue de la remontée des gradients. Les résultats des levés magnétiques ontété utilisés pour différencier les dykes de granite et les dykes de dolérite avec des contrastes de résistivité trop faibles. L'étude géomorphologique seule n'aurait pu suffireà comprendre le potentiel des eaux s...
