2. INTRODUCTION
Water is essential to all life forms.
Water is an essential resource for the development of Agriculture, Industries
and living organism
Salt water in ocean, seas and saline groundwater make up about 97% of it.
Only
2.5–2.75% is fresh water, including 1.75–2% frozen in glaciers, ice and snow.
0.7–0.8% as fresh groundwater and soil moisture, and less than 0.01% of it
as surface water in lakes, swamps and rivers.
A watershed is an area of land that drains all the streams and rainfall to a
common outlet such as the outflow of a reservoir, mouth of a bay, or any point
along a stream channel
3. OBJECTIVE OF THE PROJECT
To study are prevailing geology of an area.
To study water quality of an area.
To study morphometric analysis of the basin using GIS Technique.
To interpret the ground water conditions.
To study water management of the study area.
4. METHODOLOGY
To study water quality parameter grab sampling was done.
Preparation of Drainage map, location map, Digitization etc with the help of
GIS software and toposheet no. 55H/9 & 55H/13.
Detailed Analysis of water samples collected from wells.
Collections of literature from various sources (Internet, books, Dissertation)
and study it.
To analyze and interpret the collected data

7. HYDROLOGY AND RAINFALL
Occurrence of Ground Water :-
Basaltic lava flows can still be divided into three possible subunits.
1) Weathered basalt
2) Jointed and fractured basalt
3) Vesicular basalt
These three are principal water bearing formations found in the area
Ground Water Condition :-
Ground water condition good in the southern plain of area the
condition has been further improved because of artificial
recharge by way of nalla bunding, peculation tank, etc
Depth of well ranges from 12 to 20 mt while diameter ranges from
3.05 to 5 mt.
8. Climate and Rainfall
The Climate of the study area is characterized by a hot summer and
general dryness throughout the year except during the south-west
monsoon season, i.e. June to September.
The mean minimum temperature is 15.1°C and means maximum
temperature is 42.2°C.
The normal annual rainfall over the study area varies from 700
mm to about 1700 mm.
Ground Water becomes the main sources for domestic as well as for
Irrigation purpose.
9. GEOMORPHOLOGY
The Kondeshwar Watershed comprises an area about 464 Sq.m.
It shows dendretic drainage pattern
The entire basaltic terrain can be classified as Deccan trap plateau.
The landform of highly dissected plateau occurs in the north-western and
the central part of the area.
The moderately dissected basaltic plateau landforms are occurs in the
south eastern part of the district.
The slightly dissected plateau landform is mostly undulating landform
occupying the valley areas and the plains.
12. MORPHOMETRIC ANALYSIS
Morphometry is the measurement and mathematical analysis of the
configuration of the earth's surface, shape and dimension of its landforms.

22. CONCLUSION
Chemical testing of water showed Ca and Mg hardness above the
permissible limit of drinking water standard which makes the water hard to use it
for domestic purpose.
Only the well water at katamla village showed higher alkalinity. Overall it can
be
reduce that after removing hardness the water can be safe to use for drinking
purpose.
Morphometric analysis of drainage basin or channel network plays an importan
role understanding hydrological behaviour of drainage basin.
Morphometric analysis of Kondeshwar river basin shows the dendretic drainag
pattern.
23. The analysis has revealed that the total no. and length of stream
segment is maximum in first order streams and decreases as the
stream order increases.
The result demonstrated the presence of structural, denudation, and
alluvial landforms.
The area fall under “Over-Exploited” category, the existing dug and
Bore wells may also be used for artificial recharge of ground
water.
