These are fault / fracture zones, which generally act as
conduits for movement of ground water in hard rocks. Along these
zones, the yields are significantly higher and wells are likely to
be sustainable for longer duration. However, the inferred fractures
need to be confirmed by detailed ground surveys.
N.B.-The depth range and yield range of wells may vary within
the unit because of certain inhomogeneities. Fractures/Lineaments
which are clearly observed / inferred from the satellite image are
indicated on the map. There could be some obscured fractures which
also influence the ground water prospects.Locations of the recharge
structures shown in the map are tentative. This map is useful for
narrowing down the target zones,and exact location on the ground
for wells and recharge structures should be identified based on
follow-up ground hydrogeological/geophysical surveys.
