Pediments, Pediplain, Valley, Ridges have been deline-
ated based on image characteristics. Valleys are the un-
consolidated sediments deposited by streams/rivers,
normally in narrow fluvial valley and constitute boulders,
cobbles, pebbles; gravels, sand and silt, cover nearly
34.5% of the study area. Pediplains are gently sloping,
smooth surfaces of erosional bed rocks resulting from
coalescence of two or more pediments. Pediplains oc-
cupy 52.25% of the total study area. Structural hills
comprising meta-igneous rocks show linear to arcuate
pattern covering 1.39% of the area. Pediments occur at
the foot hills and occupy 11.86 % of the study area.
8. Conclusion
The study reveals that GIS and remote sensing can be
very useful in evaluation of various morphometric pa-
rameters and its influence on landforms. Interpretation of
satellite images can help delineate lithological and geo-
morphic units. GIS facilitates analysis of various mor-
phometric parameters and acts as an effective tool in es-
tablishing relationship between drainage morphometry
and properties of landforms. The study also reveals that
DEM can useful in studying the topography within GIS
environment. Geomorphological study of an area is the
systematic study of present day landforms, related to
their origin, nature, development, geologic changes re-
corded by the surface features and their relationship to
other underlying structures. Therefore, it has become an
integral part of groundwater study of an area. Some
morphometric elements (measurement of landforms)
provide valuable information for groundwater condition.
The morphometric parameters evaluated using GIS
helped to understand various terrain parameters such as
nature of the bedrock, infiltration capacity, runoff, etc.
Similar studies in conjunction with high resolution satel-
lite data help in better understanding the landforms and
their processes and drainage pattern demarcations for
basin area planning and management [17].
