Geomorphology of Area
Landform can be described as a geomorphic
unit that is produced on the surface of the earth by
the action of various geological agencies working
on it. The resultant form is also the representative
of geological agencies by which it has been produced
in the geological past. Geomorphological features
influence the occurrence, storage and movement of
groundwater and therefore the study of
geomorphology is eminent in groundwater
prospecting. In view of this a geomorphological map
of the area has been prepared using an IRS 1c, LISS-
III Satellite Image. Since the area is covered with
older geological formations it exhibits mostly
denudational landforms along with depositional
landforms of fluvial origin and residual landforms
of recent age. Refer map 1.2
Groundwater Potential
The aquifer characteristics such as yield,
specific capacity, and transmissivity and storage
coefficient have been assessed through well

inventory and aquifer performance tests. During this
process it has been observed that the yield of the
wells ranges from 18 to 54 kiloliters/day during
winters while the same is as low as 15 to 25 kiloliters/
day during summers. Two major geological
formations of the area, viz., limestone, sandstone is
acting as prominent aquifers. The limestone with
its fractured and jointed nature has rendered it as
prominent aquifer. The sandstone because of its
porosity is acting as a prominent aquifer. Eight
aquifer performance tests were conducted on dug
wells in the watershed and the results of the aquifer
performance tests are given. (Aquifer Performance
of Naini Watershed) which shows that the specific
capacity of the well is from 1.57 to 519.8 liters/
minute/meter of drawdown. The transmmisivity is
3.94 to 94.45 sq meter/meter of aquifer width per
day. The storage coefficient is 0.01 to 0.05
Analytical Study
The resources situation described above has
been critically analysed with factors controlling the
