will generate lower relative relief. Highest relative relief is only 11.20 m/km 2
and is found at the west central part of the study area. Relative relief of the
study area is classified in four relative relief zones, like <3, 3-6, 6-9 and >9 m/
km 2 . Around 84 % of the total study area is under <3 m relative relief category.
Next category of relative relief zone is 3-6 m/km 2 and it covers 13 % of total
area. This zone is distributed over the south central, central, west central, north
west and north east parts of study area. The third category of relative relief is
6-9 m/km 2 and it covers about 3 % of area. This zone is distributed in west
central, north west central and central parts of study area. Last category is more
than 9 m/km 2 . It covers less than 1 % (0.42 %) of the area and is located in cen-
tral part of study area (Fig. 3 ). The lower relative relief indicates that the region
is almost flat land and appearing mature stage of geomorphic evolution. Lower
relative relief suggests the availability of water, hence the region can be con-
verted to a very good agricultural region. Although maximum area is covered
under <3 m/km 2 relative relief zone but the presence of surface water resources
are limited.
