ABSTRACT
Land and water resources are depleting at global as well as in India as the population grows. The need of food, fiber
and water is also increasing day by day to feed this ever-increasing population. Production process is impossible without
natural resources, therefore conserved and utilized of land and water resources in an efficient manner is the only way for
sustainable development of human being. Conservation of natural resources is a site specific, therefore effective site-specific
planning is the most important parameter. In the current technical era Remote Sensing (RS) and Geographical Information
System (GIS) plays a vital role for site specific planning of natural resources. Therefore, in the present study RS and GIS Tools
are used for Morphometric Analysis of Bhama river basin of Pune district, Maharashtra, India. Digital Elevation Model (DEM)
based watershed delineation and prioritization Bhama watershed was done by using Geospatial tools. The work outlines the
significance of digital elevation model for assessment of drainagepatternand extractionofrelativeparameters.Basinhasbeen
divided into 11 sub-watersheds namely SW1 to SW11. It has been observed that the watershed's mean bifurcation ratio was
9.17, indicating a low mountainous region and a low drainage density of 3.2 km/km2, which very well fits the moderate soil
texture, which signifies strong infiltration and minimal runoff owing to extensive forest cover. Lowerpeaksoflongerduration
with elongated watershed favor lower form factor ratio and elongation ratio of 0.25 and 0.57, respectively,whichishelpful for
preventing floods in downstream. The relatively low relief ratio of 0.018 correlates to modest erosion intensity. A modest
roughness number of 2.28 is the result of low drainage density and relief. The stream order of watershed ranges from first to
sixth order and have dendritic drainage pattern means homogeneityintextureandlack ofstructural control.Itwasconsidered
as high priority for adopting conservation measure as well results were showing the appropriate measure structure locations
for preventing the soil from getting eroded from the highly prioritized sub-watershed.

INTRODUCTION
The measuring and mathematical study of the configuration of the earth's surface, shape, and size of its landforms is
known as morphological analysis. The use of quantitative analysis of morphometric characteristics in river basin evaluation,
watershed prioritizing for soil and water conservation, and natural resource management at the watershed level has been
discovered to be quite beneficial. Any hydrological research, such as groundwater potential evaluation, groundwater
management, pedology, and environmental assessment, requires morphological analysis (Sreedevi et al., 2009).
Hydrologists and geomorphologists have discovered that some relationships existbetween runoffcharacteristicsand
drainage basin system geographic and geomorphic properties. Physiographic propertiesofdrainagebasins,suchassize,form,
slope of drainage area, drainage density, size and length of contributories, and so on, can be linked to a variety of key
hydrologic phenomena. For morphometric analysis, remote sensing techniques employing satellite pictures and aerial
photography are useful. Satellite remote sensing is highly effective in assessing drainage morphometry since it can offer a
synoptic picture of a vast area.
In a watershed management programme, particularly in case of large watersheds, it may not be possible to treat the
entire area of the watershed with land treatment measures. Identification andselectionoffewareasorsub-watershedshaving
relatively more degradation problem, for development planning and implementation of conservation activities according to

level of need and status of degradation, are required. These few selected areas orsub-watershedswithina largewatershedare
called the priority watersheds. In this process, collection of sufficient bio-physical and socio-economicinformationisrequired
for integrated watershed management planning. After effectively prioritization of watersheds (sub-watersheds), a sub-
watershed management plan for each priority sub-watershed is prepared in order to minimize natural and human-induced
hazards and to conserve valuable resources (soil, water, biodiversity and socio-cultural aspects)
MATERIAL AND METHOD
STUDY AREA
The Bhama watershed is situated near pune city at altitude ranging from 1272 to 559. The Bhama basin is one of the
sub-basins of Bhima river basin. The geographical location of research area is shown in fig 1. the total area by the basin under
study is 397.71 km2. The place is situated in the scenic area of Sahyadri’s (western Ghats) The studyarea issituated alongwith
the western margin of the Deccan Plateau, and on leeward side of the Western Ghat crown. The study area is surrounded by
hilly regions on its west as well as in south side. the geographical location of study area extends between 18°42'33.5"N to18°
59' 57.5" N latitudes and 73° 31' 40.5" E to 73° 56' 45.5" E longitudes
Study area situated on the lower site of the western ghat hence the climate of Pune is always moderate.Theclimate of
the study area is tropical monsoon type. The climate shows the three distinct seasons summer winter and monsoon. All the
seasons mainly persist for more or less four months duration.
There is a significant variation in temperature conditions in western Maharashtra throughout the year. Highest
temperature recorded in the month of May which exceeds 38°C whereas in winter lowest temperature was recorded less
than 15°C. Being benefitted of location in western ghat Monsoon starts in the area during June& receives up to the
September end. Rest of the months are usually without spells and the months April and May sometimes gives torrential
rainfall due to local climatic conditions. Avege annual rainfall recorded was 2700 m

DATABASE AND METHODOLOGY
The survey of India toposheet numbers 47 F/9, 47 F/13, 47 F/14, on scale of 1:50000 were used for present study. The
toposheet maps were georeferenced on GIS platform with WGS 1984 datum and digitized the roads and villages.
The Strahler and Chow (1964) approach was used to organize the streams. The morphometric parameters were
determined using the approach outlined in Table. The drainage map was created using the Geospatial tools using a 30 m 30 m
resolution Digital Elevation Model (DEM) retrieved from NASA's USGS Earth Explorer Portal,whichwasinitiallycreatedusing
the Shuttle Radar Topography Mission (SRTM) The stream order map was created using the basin's prepared drainage map
using GIS Tools. The Stream Organize feature of the Spatial Analyst Hydrology tool in GIS Tools may be used to order streams.
Using GIS Tools Editor tool, the stream sorting was done manually. At the same time, each stream segment was modified and
the stream order was entered into the characteristics database. To modify the direction of flow and combine the stream
segment, several tools such as clip and merge were employed. Figure shows a prepared stream order map of the research
region. The stream order map was utilized for additional morphological analysis, such as manually counting the number of
streams in each stream order and measuring the length of individual streams for further research. The Table lists several
morphometric characteristics calculated for the research region, including linear, areal, and relief aspects.

RESULT AND DISCUSSION
LINEAR ASPECTS
Linear aspects of drainage network are also referred as linear aspect of channel system. This includes the analysis of
stream' order, stream length and length of overland flow, mainly.
Stream Order (Su)
The first step in morphometric study of a drainage basin based on hierarchy is stream order designation (Strahler,
1952). The Bhama River Basin was discovered to be a 6th order trunk stream. The Bhama river's maximum stream order
frequency is found in first-order streams, then second-order streams, and finally third-orderstreams,beforedecreasingtothe
last highest order stream.
1st Order Stream (Suf)
The first order streams are the youngest streams in watershed. These streamsareresponsibletosoil erosioninlarger
scale. In Bhama watershed have 4854 1st order streams
Stream Number (Nu)
Stream number is defined as the sum of order-wise stream segments. The inverse of stream order is stream number.
The first, second, third, fourth, fifth, and sixth streams have stream numbers of 4854, 701, 178, 49, 6, and 1 correspondingly.
Because the basin has a large number of first-order streams, it is responsible for the rapid removal of water after heavy rain.
Stream length (Lu)
Using SOI topographical sheets and GIS Tools in software, total stream lengths were determined. Hortons law states
that geometric similarity is kept in increasing order watersheds (Strahler, 1964).
Stream Length Ratio (Lurm)
Horton (1945) determined the length ratio by dividing the man length of the order's segment(Lu)bythemeanlength
of the next lower order's segment (Lu-1) which is constant across the basin's successive orders. When the stream length ratio
rises from the lowest to the highest order, the basin has reached its mature geographic stage.
Mean Stream Length (Lum)
The drainage network components and contributing watershed surface are related to mean stream length (Lum)
(Strahler, 1964). It's calculated by dividing the overall length of an order's stream by the total number of segments.
Figure 5: - Drainage Map of Bhama Watershed

Bifurcation ratio (Rb)
The number of stream segments of a given order (Nu) is divided by the number of streams in the next higher order
(Nu+1) to compute the bifurcation ratio. The bifurcation ratio is a relief and dissertation index. A dimensionless feature is the
bifurcation ratio. Lower bifurcation ratio values (less than 5) suggest that the watershed has less structural disturbances
(Strahler, 1964) and that the drainage pattern has not been distorted (Nag 1998). A greater bifurcation ratio (>5) shows that
the drainage pattern is under strong structural control, whereas lower values suggest that the watershed is not impacted by
structural disturbance. The bifurcation ratio of 5.732 indicates that drainage pattern is influenced by geological structure.
Weighted mean Bifurcation ratio (Rbwm)
Strahler (1953) calculated the mean of the sum of the bifurcation ratios of each successive pair of orderstoarriveat a
more representative bifurcation ratio by multiplying the bifurcation ratioof eachsucceedingpairoforders bythetotal number
of streams in this ratio. For this, the Rbwm value achieved is 5.7.
Length of main channel (Cl)
The length of the longest watercourse from the watershed's outflow point to the uppermost watershed boundary is
known as the length of the main channel (Cl). Using GIS Tools, the length of the main channel (Cl) was calculated to be 75.88
km.
Channel Index (Ci) & Valley Index (Vi)
For determining valley length, channel length, and the shortest distance betweentheriver'smouthandsource(Adm).
The channel index and valley index are computed using Adm. 1.48 and 1.45, respectively, arethecalculatedChannel Index(Ci)
and Valley Index (Vi).
RHO coefficient
The RHO coefficient is determined by dividing the bifurcation ratio by the stream length ratio. The RHO coefficient
determines the relationship between drainage densityandbasinphysiographicdevelopment(Horton,1945).Climate,biologic,
anthropogenic, and geomorphologic factors all influence the RHO coefficient. For this researchregion,theRHOcoefficientwas
calculated to be 0.77.

Areal aspect
Drainage density (Dd), Stream frequency (Fs), Drainage Texture (Rt), Form Factor (RF), Elongation ratio (Re),
Circularity ratio (Rc), Length of overland flow (Lg), Constant of channel maintenance (C), Lemniscate (k), Infiltration Number
(If), and Basin perimeter (P) were calculated for the drainage basin (watershed) and the results are shown in Table 4.
Length of basin (Lb)
The longest dimension of a basin parallel to the maindrainagelineiscalledbasinlength(Schumm,1956).Accordingto
Schumm (1956), the distance is 39.25 kilometers.
Basin area (A)
The area is just as important as the other metric, which is the overall length of the stream. The basin area, which is
396.71 km2, was calculated using GIS Tools in software.
Basin Perimeter (P)
The basin perimeter is the outermost edge of the basin that encloses the area. The size and shape of a watershed are
determined by the basin perimeter. Using GIS Tools , the basin perimeter is calculated and found to be 132.09 km.
Length area relation (Lar)
Lar = 1.4* A0.6 formula proposed by Hack (1957) gives the relation between the stream length and basin area
Lemniscate’s (k)
Chorely (1967) uses a Lemniscate value to determine the slope of the basin. It is calculated using the formula k=
Lb2/4*A, where Lb is the basin length in kilometers and A is the basin area in square kilometers. k is determined to be 3.88 in
the computed value.

Form factor (Ff)
The dimensionless form factor, often known as an index, is used to express the various basin shapes (Horton, 1932).
The form factor ranges from 0.1 to 0.8. A higher form factor number indicates a circular basin, while a lowervalueindicates an
elongated basin. The shape factor ranges from 0.78 to >0.78 for elongated basins and >0.78 forcircularbasins. Theformfactor
value for the Bhama river basin is 0.38, indicating that the basin is elongated.
Elongation ratio (Re)
The diameter of a circle with the same area as the basin divided by the maximum basin length is known as the
elongation ratio (Schumm, 1956). Strahler claims that the elongation ratiovariesfrom 0.6to1.0acrossa widerange ofclimatic
and geology types. The elongation ratio is used to classifytheslopeofa watershed:elongated(0.5-0.7),lesselongated(0.7-0.8),
oval (0.8-0.9), and circular (0.5-0.7). (0.9-0.10). Bhama river basin's elongated ratio is 0.69, indicating that the basin is
elongated.
Texture ratio (Rt)
The texture ratio (Rt= NI/P) is the proportion of first-order streams to the basin's perimeter, and it is affected by
lithology, terrain relief, and infiltration capacity. Texture ratio is a significant measure in morphometric analysis since it is
affected by infiltration capacity, terrain relief, and lithology. This basin's texture ratio was discovered to be 22.527.
Circulatory ratio (Rc)
Circularity ratio is a dimensionless characteristic that measures the degree of circulation across thebasin.Circularity
ranges from 0 to 1, with a value near to 1. The circulatory ratio is computed by dividing the surface area of the watershed by
the surface area of a circle with the same perimeter as the watershed. The circulatory ratio of the basin fluctuates between 0.4
and 0.6, according to Miller (1953), indicating that the basin is elongated and made up of extremely permeable geological
components. The circulation ratio of the basin is 0.4, indicating that it is of the elongated type.
Drainage texture (Dt)
The drainage texture is computed by dividing all stream segments by the area's circumference (Horton, 1945).Smith
(1950) defined five drainage texture classifications: extremely fine (>8), fine (6 to 8), moderate (4 to 6), coarse (2 to 4), and
very coarse (2). The drainage texture of the basin is assessed to be 28.63, indicating an extremely fine texture.
Compactness coefficient (Cc)
The compactness coefficient (Cc) is computedbydividing thewatershed'sperimeterbythecircumferenceofa circular
region equal to the watershed's area (Gravelius 1994). The slope, but not the area of the watershed, determines the
compactness coefficient. The basin's Cc was discovered to be 1.21.
Fitness ratio (Rf)
The fitness ratio is the length of the main channel divided by the perimeter of the watershed. The fitness ratio is a
topographic fitness metric (Melton 1957). Bhama basin has a fitness ratio of 0.35.
Wandering ratio (Rw)
The wandering ratio (Rw) is the ratio of the length of the main stream to the length of the valley (Smart & Surkan
1967). The valley length is the straight-line distance between the basin outflow and the ridge's remost point. The wandering
ratio was determined to be 1.24 in this investigation.

Watershed Eccentricity (τ)
τ = [(|Lcm2 -Wcm2|)] is the expression for watershed eccentricity. Watershed eccentricity,Lcm=Straightlengthfrom
the watershed mouth to the watershed's center of mass,andWcm= Watershed'swidthatthecenterofmassandperpendicular
to Lcm The eccentricity of the watershed is a one-dimensional characteristic. The watershed eccentricity is calculated to be
0.42 for the specified watershed.
Centre of Gravity of watershed (Gc)
The length from the watershed's outflow to a point on the stream closest to the center of the watershed is used to
determine the watershed's Center of Gravity (Gc). The watershed's center of gravity was determined using Geospatial Tools,
and it is located at latitude 18.99N and longitudes 74.75E.
Sinuosity Index (Si)
Sinuosity describes the channel layout of a drainage basin. Sinuosity is the ratio of channel length to down valley
distance. The Sinuosity value ranges from 1 to 4 and beyond. Geomorphologists, Hydrologists, and Geologists all utilize the
Sinuosity Index. Hydraulic, topographic, and standard sinuosity indexes were calculated and found to be 16.66 percent,83.33
percent, and 1.05 percent, respectively.

Stream frequency (Fs)
Stream frequency refers to the number of stream segments per unit area. The frequency of a stream is also known as
the frequency of a channel (Horton 1932). The watershed's stream frequency was discovered to be 4.283.
Drainage Density (Dd)
Drainage density refers to the length of a stream per unit area in a watershed(Horton, 1952).Usingthespatial analyst
tool in Geospatial Tools, the drainage density was determined. Dd is classified as extremely coarse (less than 2), coarse (2-4),
moderate (4-6), fine (6-8) or very fine (>8). The basin's Dd was discovered to be 2.49, indicating a coarse drainage basin.

Infiltration Number (If)
If=Dd*Fs, the infiltration number is equal to the product of drainagedensity(Dd)and streamfrequency(Fs).Agreater
infiltration number indicates a lesser infiltration capacity and more runoff (Horton1964). The infiltration number (If) for the
basin is 10.66, indicating that the basin has a lesser infiltration capability and more runoff.
Drainage pattern (Dp)
The drainage pattern (Dp) is useful for determining the stage of erosion. Slope, lithology, and structure all have an
impact on drainage patterns. Dendritic and radial patterns may be found in the research region. Howard (1967) made a
connection between drainage patterns and geological data.
Length of Overland flow (Lg)
Overland flow length (Lg) is half the reciprocal of drainage density. Lower relief is indicated by a longer duration of
overland flow, and vice versa. Low value (0.2), moderate value (0.2-0.3), and high value (>0.3) are the three categories for
length of overland flow values. A lower Lg value suggests greater relief, more runoff, and less infiltration, whereas a higher Lg
value indicates a gentle slope, more infiltration, and less runoff. The length of the overland flow (Lg) is 0.2, which indicates
moderate to high relief, runoff, and infiltration.
Constant of Channel Maintenance (C)
Constant of Channel Maintenance (C=1/Dd) is the inverse of drainage density. Constant channel maintenance of
watershed is computed to be 0.4

Relief aspect
Relief refers to the relative height of points on surface and lines with respect to the horizontal baseofreference.Relief
expresses the magnitude of the vertical dimension of the landform.
Maximum basin relief (H)
The elevation difference between the highest pointinthe catchmentandthecatchmentoutflowisknownasmaximum
basin relief (H). The relief of the basin is 396 meters, indicating that the basin has undulating topography with high kinetic
energy of water, resulting in significant soil erosion.
Relief ratio (Rhl)
The total relief of a river basin is the difference in elevation betweenthehighestand lowestpointsinthe watershed on
the valley floor. The relief ratio is the proportion of a basin's overall relief toitslongest dimensionparallel tothemaindrainage
line (Schumm, 1956). The river basin relief ratio was determined to be 0.0063 in this research region.
Relative relief (Rhp)
The formula published by Melton (1957) for calculating relative relief is Rhp= H*100/P, where P is the perimeter in
meters and H is the total basin relief.
Absolute relief (Ra)
The difference between a specific site and sea level is known as absolute relief. Using Geospatial Tools, the absolute
relief is estimated and determined to be 898 m.
Channel gradient (Cg)
The Channel Gradient (Cg) m/Kms is computed using Broscoe's (1959) formula: Cg = H / (/2) * Clp, where H is the
total basin relief and Clp is the longest dimension parallel to the Principal drainage line (Clp)Kms.Theresearcharea'schannel
gradient is determined to be 3.37.
Ruggedness Number (Rn)
The ruggedness number is used to determine theunevennessor roughnessofthesurface(Rn).Theroughnessnumber
is the product of basin relief and drainage density (Strahler, 1968). The slope steepnessandlengtharecommonlycombinedto
get the ruggedness number. The study area has a toughness rating of 0.986.

Melton Ruggedness number (MRn)
The Melton Ruggedness number is a slope index that provides a unique depiction of the relief ruggedness within a
watershed (MRn). The MRn for the research area is 10.28.
Gradient ratio (Rg) :-
The indicator of the channel slope which enables the assessmentofrunoffvolume(Sreedevi,2004).TheRgforthestudyarea is
0.0061.
Gradient & channel slope (Sgc)
The gradient stated as a change between its vertical intervals (Vei) reduced to unity and its horizontal counterpart is
the steepness of slope (Hoe). The formula Sgc= Vei/Hoe is used to compute the gradient.
Slope analysis (Sa)
Slope analysis (Sa) is calculated by using Geospatial Tools. It is the average slope in the degree. It is found to be
0.01422 for the study area.
Average slope of overall basin (S)
The average slope was used to investigate the erodibility of a watershed (Wenthworth 1930). When the slope % is
higher, erosion is higher. The slope of the watershed is 1.422 percent when calculatedusingthemethodS=(Z*(Ctl/H))/(10*
A).
Mean slope of overall basin (Ѳs)
The formula s = (Ctl * Cin) /A is used to calculate the mean slope of the basin, where s is the overall slope, Ctl is the
total length of the contour in the watershed, A is the area of the watershed, and Cin is the contour interval. The Bhama
river basin's mean slope has been calculated to be 0.063.

Hypsometry :-
Hypsometric analysis describes the distribution of elevation data across an area of land surface. The elevation
distribution across a land surface is described through hypsometric analysis. It's a useful tool for assessingandcomparingthe
geomorphic evolution of different landforms, regardless of the factors that may have caused it. Tectonics and/or climate, as
well as lithological variation, are key determinants of landscape evolution. In present study we hypsometric curves of 11 sub
watersheds of Bhama River The hypsometric integral has been employed as a morphometric parameter to determine thelink
between watershed area and hypsometric analysis. These factors were statisticallyanalyzedbycategorizingthemintodistinct

of Bhama Watershed
The above Hypsometric Curves Concluded that the drainage network of SW1, SW5, SW10, SW11 is in maturity stage,
in SW2 and SW3 the drainage network is in young stage SW6, SW8 is in between maturity and old stage and SW4, SW7, SW9
drainage network is in old stage . the Hypsometric curve of whole Bhama watershed shows that the drainage network of
watershed is in old stage this means that the soil erosion in watershed is not going to increase by means of drainage of basin.

Prioritization:-
In a watershed management programme, particularly in case of large watersheds, it may not be possible to treat the
entire area of the watershed with land treatment measures. Identification andselectionoffewareasorsub-watershedshaving
relatively more degradation problem, for development planning and implementation of conservation activities according to
level of need and status of degradation, are required. These few selected areas orsub-watershedswithina largewatershedare
called the priority watersheds.
In this process, Morphometric analysis used for prioritization of micro-watersheds by studying different linear and
aerial parameters of the watershed even without the availability of soil maps. After effectively prioritization of watersheds
(sub-watersheds), a sub-watershedmanagementplanfor eachprioritysub-watershed ispreparedinordertominimizenatural
and human-induced hazards and to conserve valuable resources (soil, water, biodiversity and socio-cultural aspects). And
finally, various integrated watershed management activities in the selected priority watershed (sub-watershed) is
implemented
The various morphometric parameters such as area, perimeter, stream order, stream length, stream number,
bifurcation ratio, drainage density, streamfrequency,drainagetexture,lengthofbasin,formfactor,circulatoryratio,elongation
ratio, length of overland flow, compactness coefficient, shape factor, texture ratio is computed. The linear parameters such as
drainage density, stream frequency, bifurcation ratio, drainage texture, length of overland flow havea directrelationshipwith
erodibility. Higher the value, more is the erodibility. Hence for prioritization of sub-watersheds, the highest value of linear
parameters is rated as rank 1, second highest value is rated as rank 2 and so on, and the least value is rated last in rank. Shape
parameters such as elongation ratio, compactness coefficient, circularity ratio, basin shape and form factor have an inverse
relationship with erodibility. Lower the value, more is the erodibility. Thus, the lowest value of shape parameters is rated as
rank 1, next lower value was rated as rank 2 and so on and the highest value is rated last in rank. Hence, the ranking of the
micro watersheds is determined by assigning the highest priority/rank basedonhighestvalueincaseoflinearparametersand
lowest value in case of shape parameters.
The prioritization is carried out by assigning ranks to the individual indicators and a compound value (Cp) is calculated.
Watersheds with highest Cp are of low priority while those with lowest Cp are of high priority. Thus, an index of high,
medium and low priority is produced

CONCLUSION
The morphometric characteristics of different sub watersheds shows their relative characteristics with respect to
hydrologic response of watershed it has been observed that the watershed's mean bifurcation ratio was LOW Mountainous
Region and a LOW drainage density which very well fits the moderate soil texture, which signifies strong infiltration and
minimal runoff owing to extensive forest cover. Lower peaks of longer duration with elongated watershed favor lower form
factor ratio and elongation ratio which is helpful for preventing floods in downstream. Therelativelylowreliefratio correlates
to modest erosion intensity. A modest roughness number is the result of low drainage density and relief . Low, Medium and
high priority the prioritization analysis revels that the SW9, SW10, SW11 Are the zones having Lowest compound score and
were considered under high priority which clearly indicates that maximum soil erosion and hence these may be taken for
conservation structures firstly. Medium prioritized zone is shown for SW1, SW4, SW7, SW8. And SW2, SW3, SW5, SW6 these
watersheds have low compound score so assigned Low Priority for this compound score
