INDIA

ABSTRACT
Geological and hydrogeological studies of an aquifer in the Kuteshwar
limestone deposit area, Madhya Pradesh, India show a highly cavernous and
karren limestone on the left bank of the Chhoti Mahanadi River, while the
right bank consists of thick porcellanite deposits in addition to the limestone.
These thick porcellanites are practically impervious silts and clays that
act as barriers to surface and subsurface water flow. Though the limestone
deposits show easterly dips, subsurface water flow from the river into
the mined areas, which are located on the eastern side of the river and
the barrier, is insignificant. Thus a large number of shear zones, faults
and karren structures developed in the mining region east of the porcellanite
barrier became isolated. These investigations, and inferences from earlier
studies, reveal that groundwater flow is controlled by intensely developed
conduits in the western part of the area. In the eastern part, flow is
controlled by aquifers that consist of two major formations, limestone
with various degrees of karstification and fractured porcellanite. Aquifer
thickness varies enormously and this variation contributes significantly
to the spatial variability of aquifer parameters.
