摘要: Mise-a-la-masse technique has been applied to map water filled fracture1 struck in bore wells a small watershed near Hyderabad. The area consists of hard crystalline rock mainly granite where groundwater is mostly tapped from iractured rock. In the watershed, 25 have drilled fairly distributed over on basis results Vertical Electrical Soundings (VES) study conditions weatheredffractured aquifer system. and Spontaneous Polarization (SP) investigations were carried out at five these sites, delineate lateral extension fractures. anomalies are clearly indicative four locations some indication seen fifth location. Two encountered fractures same depth as experimental site. It concluded that mise-a-la-masse supplemented with S.P. could be helpful delineating
