Description 542-553
In
the present investigation 50 (Vertical electrical sounding) survey were carried
out in the study area. Field data were interpreted by curve matching techniques
in IPI2WIN software to determine the resistivity and thickness of the different

layers.
By using conventional GIS method, the spatial distribution maps for weathered
zone and fracture zones resistivity and thicknesses were prepared. Integration
of the said themes was carried out in GIS. Integration analysis was carried out
with weathered zone thickness and a resistivity map. This map was superposed
over geology map. To locate the shallow groundwater zones. Overlay analysis was
used in the thickness of first and second layer fracture zone with the
corresponding resistivity maps. This map was superposed over geology map. The
suitable zones for groundwater were delineated from first layers combinations
of low resistivity with more thickness in areas occupied by Dunite,
hornblende-biotite-gneisses and

charnockite.
Depth for the construction of tube-wells and dug-wells were suggested in the
present investigation. Spatial distribution variation results are given in the
findings.
