Abstract: Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. The
Study Area lies between 750 29’ 19” E and 76
0 37’ 40” E longitude and 11
0 55’ 54” N and 13
0 23’ 12.8” N latitude. The study
area covers an area of 10874.65 km2, having maximum length of 143.73 km. Drainage density is 1.43 km/km
2 hence area is of
coarse texture. The length of overlandflow is less than 0.4 indicating more runoff less infiltration. The study of hypsometric
properties of watershed using hypsometric integral (HI) and hypsometric curve retrieved in that, HI value is 0.57 and hence
watershed falls under the Mature Stage. Circularity ratio is 0.26 which shows that the drainage area is less circular.
Keywords: DEM, Drainage Density, GIS, Hypsometry, Stream Frequency, Stream Length.
I. INTRODUCTION
The Cauvery river enters Tamil Nadu at Hognekal of
Dharmapuri district from the west and takes a southern
course from Mettur and again takes south-eastern course at
Erode and then flows to Bay of Bengal flowing through
Trichirapalli, Thanjavur and Cuddalore districts. The study
area forms part of Cauvery basin, which lies on left banks of
Cauvery river. Lakshmantirtha river is a major tributary to
river Cauvery and has its originates in Brahmagiri Devasi
Hills of Western Ghats in southern Kodagu district and
flows through a distance of about 130 km. It enters the
Mysore district near Chikkahejjur, south west of Konana
Hosahalli in Hunsur taluk and flows through Hangodu,
Hunsur and Kattemalavadi before its confluence with
Cauvery on the right side at Sagarkatte in Krishnarajanagar
taluk.
Watershed is a natural hydrological entity from which runoff
resulting from precipitation flows past a single point into
large stream, river, lake or ocean. Morphometric analysis
provides quantitative description of the basin geometry to
understand initial slope or inequalities in the rock hardness,
structural controls, recent diastrophism, geological and
geomorphic history of drainage basin (Strahler, 1964).
Morphometric analysis requires measurement of linear
features, gradient of channel network and contributing
ground slopes of the drainage basin. . A major emphasis in
geomorphology over the past several decades has been on
the development of quantitative physiographic methods to
describe the evolution and behavior of surface drainage
networks (Horton, 1945). The influence of drainage
morphometry is very significant in understanding the
landform processes, soil physical properties and erosional
characteristics. The hypsometric analysis can be used as a
morphometric parameter, i.e. hypsometric integral, to
deduce its relationship with the area of watersheds.
Statistical analysis of these parameters has been carried out
by classifying them into different classes based on the
natural breaks method. This brings out strong relationships
for hypsometric integral classes and area classes with the
number of watersheds in respective classes and the total area
occupied by respective hypsometric and area classes.

2.2 Methodology
2.2.1 Morphometric analysis DEM data is used to calculate the flow direction a staple for
determining many important hydrologic parameters stream
network is determined by using Arc GIS tools. Quantitative
morphometric analysis was carried out for watershed for
linear aspects, areal aspects and relief aspects. The analysis
was carried out using Arc GIS.

2.2.2 Hypsometric Analysis The curve shows how much area lies above and below
marked elevation intervals. The areas used are therefore
those of horizontal slices of the topography at any given
level. This method produces a cumulative curve, any point
on which expresses the total area (reduced to horizontal
projection) lying above that plane [4].
The curve can also be shown in non-dimensional or
standardized form by scaling elevation and area by the
maximum values. The non-dimensional hypsometric curve
provides a hydrologist or a geo-morphologist with a way to
assess the similarity of watersheds.
A hypsometric curve is a histogram or cumulative
distribution function of elevations in a geographical area.
Differences in hypsometric curves between landscapes arise
because the geomorphic processes that shape the landscape
may be different.
Hypsometric curve is developed and maintained in a steady
state as relief slowly diminishes. The monadnock phase with
abnormally low hypsometric integral, when it does occur,
can be regarded as transitory, because removal of the
monadnock will result in restoration of the curve to the
equilibrium form. From inspection of many natural
hypsometric curves and the corresponding maps, A N
Strahler estimates that transition from the inequilibrium
(youthful) stage to the equilibrium (mature) stage
corresponds roughly to a hypsometric integral of 60%, but
that where monadnocks become conspicuous features the
integrals drop below 35%.The hypsometric integral was
estimated using the elevation-releif ratio method proposed
by Pike and Wison (1971).
The relationship is expressed as
Where,
Emean = mean elevation of the watershed
Emin = minimum elevation within the watershed
Emax = maximum elevation within the watershed.

falls under the mature stage.

IV. CONCLUSIONS
The length of overland flow in present study is less than 0.4.
Hence, the Watersheds selected for study have smaller flow
paths associated with less infiltration and high runoff. The
drainage density reflects the land use, affects the infiltration
and watershed response time between precipitation and
discharge. The drainage density of the area is 1.43 km/km2
indicating that the area is coarse texture. The shape ratio
shows the Study area is less elongated to oval shape. Stream
frequency is Low. The bifurcation ratio is a dimensional
property and it ranges between 3 and 5 for watersheds in
which the geologic structures do not distort the drainage
pattern. The values of relief is 1123 m indicates that the
watershed has enough slope for the runoff to occur from the
remote point of the watershed to mouth. Circularity ratio is
0.26 which indicates the area under consideration is in the
mature stage. The higher relative relief indicates that it is
composed of resistant rock patches and lower relief ratio
indicates less resistant patches of rocks. The study of
hypsometric properties of Subbasin using hypsometric
integral (HI) and hypsometric curve retrieved in that, HI
value is 0.57 and hence Area falls under the Mature Stage.
