    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.

    Fig 5 Stream Order

    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.

    The study of hypsometric properties of the present area

    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.
