A GIS based morphometric analysis of Kandaihimmat Watershed, which is a part of Tawa river basin of Hoshangabad district, Madhya Pradesh India, was carried out in the study. Drainage map of the watershed was prepared from Survey of India Toposheets (SOI) No.55 F/14 on scale 1: 50,000. Drainage pattern of watershed exhibits dendritic to the sub-dendritic pattern. The stream order range from I to Vth order. Morphometric parameters viz; number and length of streams, drainage density, drainage frequency, bifurcation and texture ratio were calculated. The shape parameters also determined include form factor, circularity and elongation ratio and basin relief. High drainage density (2.67 km/km2) of the watershed is the signature of impermeable subsoil material, sparse vegetation and high relief. High texture ratio indicates high runoff and high erosion potential of the watershed. Bifurcation, elongation, circularity ratio and form factor indicate shape of the basin as elongated to nearly c...

In this present study, Remote Sensing (RS) and Geographical Information System (GIS) techniques were used to update drainage and surface water bodies and to evaluate linear, relief and aerial morphometric parameters of the two sub-watersheds viz. Jilugumilli and Regulapadu in the northern part of West Godavari District, Andhra Pradesh. The area of Jilugumilli and Regulapadu watersheds spread over about 110 & 80 sq. km respectively. The morphometric analysis of the drainage networks of Regulapadu and Jilugumilli sub-watersheds exhibit sub-dendritic and sub parallel drainage pattern. The variation in stream length ratio changes due to change in slope and topography. It was inferred from the study that the streams are in a mature stage in Regulapadu and Jilugumilli watersheds, which indicated the geomorphic development. The variations in bifurcation ratio values among the sub-watersheds are described with respect to topography and geometric development. The stream frequencies for both sub-watersheds exhibit positive correlation with the drainage density, indicating increase in stream population with respect to increase in drainage density. The Jilugumilli watershed has a coarse drainage texture and Regulapadu sub-watershed is a fine drainage texture in nature. In the present study an attempt has been made to analyse the morphometric analysis of two sub-watersheds under different physiographic conditions. Morphometric analysis is one of the essential analyses required for development and management of watershed.
Geographical information system (GIS) has emerged as a professional tool in demarcation of drainage pattern and ground water potential and its planning. GIS and image processing techniques can be utilized for the identification of morphological characteristics and investigating properties of basin. The morphometric parameters of basin can deal with linear, areal and relief features. The present study deals mainly with the geometry, more importance being given on the evaluation of morphometric parameters such as stream order (Nu), stream length (Lu), bifurcation ratio (Rb), drainage density (D), stream frequency (Fs), texture ratio (T), elongation ratio (Re), circularity ratio (Rc), and form factor ratio (Rf) etc. Study area is Phulambri river basin located in Aurangabad district of Maharashtra state in India. The GIS based Morphometric analysis of this drainage basin revealed that the Girja-Purna is 6th order drainage basin and drainage pattern mainly in dendritic type thereby indicates homogeneity in texture and lack of structural control. Total number of streams is 1616, in which 895 are first order, 391 are second order, 196 are third order and 97 are fourth order streams and 36 of the fifth order and 1 of the sixth order. The length of stream segment is maximum for first order stream and decreases as the stream order increases. The drainage density (Dd) of study area is 0.030 km/km 2 .
A GIS-based approach in drainage morphometric analysis of Kanhar River Basin, India
Applied Water Science, 2014
The study indicates that analysis of morphometric parameters with the help of geographic information system (GIS) would prove a viable method of characterizing the hydrological response behaviour of the watershed. It is also well observed that remote sensing satellite data is emerging as the most effective, time saving and accurate technique for morphometric analysis of a basin. This technique is found relevant for the extraction of river basin and its stream networks through ASTER (DEM) in conjunction with remote sensing satellite data (Landsat etm?, 2013 and georeferenced survey of Indian toposheet, 1972). In this study, Kanhar basin a tributaries of Son River has been selected for detailed morphometric analysis. Seven sub-watersheds are also delineated within this basin to calculate the selected morphometric parameters. Morphometric parameters viz; stream order, stream length, bifurcation ratio, drainage density, stream frequency, form factor, circulatory ratio, etc., are calculated. The drainage area of the basin is 5,654 km 2 and shows sub-dendritic to dendritic drainage pattern. The stream order of the basin is mainly controlled by physiographic and lithological conditions of the area. The study area is designated as seventhorder basin with the drainage density value being as 1.72 km/km 2 . The increase in stream length ratio from lower to higher order shows that the study area has reached a mature geomorphic stage.
ARTICLE INFO ABSTRACT The quantitative analysis of drainage system is an important aspect of characterization of watersheds. Using watershed as a basic unit in morphometric analysis is the most logical choice because all hydrologic and geomorphic processes occur within the watershed. Dudhganga catchment comprises of five watersheds with a total area of 660 km² has been selected for the present study. In this paper an attempt is made to evaluate the various linear parameters (Stream order, Stream number, Stream length, stream length ratio, Bifurcation ratio, Drainage density, Texture ratio, Stream frequency) and shape factors (Compactness coefficient, Circularity ratio, Elongation ratio, Form factor) of the catchment were computed at watershed level. This was achieved using GIS to provide digital data that can be used for different calculations Copy Right, IJCR, 2012, Academic Journals. All rights reserved.

Understanding the behavior of surface drainage network is one of the important prerequisite condition for effective planning and management of water resources within the watershed. Morphometric analysis of a watershed is a crucial step in watershed development and management to understand and interpret the dynamics of drainage system of the watershed and is useful for interpretation of silent features of drainage network. A morphometric analysis was carried out to evaluate the drainage characteristics of Mohalkhad watershed which covers an area about 54 km2 in Kullu district of Himachal Pradesh in Indian Himalayan Region (IHR). Geospatial technique/tool such as Remote Sensing (RS) and GIS was used to evaluate the linear, areal and relief aspects of morphometric parameters. RS and GIS technique is very helpful over the conventional methods that are too laborious and cumbersome. To carry out this study, Survey of India (SOI) toposheet of 1:50,000 scale and ASTER DEM (30 m resolution) data were used and analysis was carried out in ArcGIS 10.5 software. Total 21 morphometric parameters of Mohalkhad watershed were evaluated considering the linear, areal and relief aspects. The significance of each morphometric parameter with the hydrological behavior of the watershed is discussed in this study. This exercise provide detailed insight into drainage system of the Mohalkhad watershed, which is useful for the development and management of water conservation measures in the area.

A morphometric analysis was carried out to describe the topography and drainage characteristics of Papanasam and Manimuthar watersheds. These watersheds are part ofWestern Ghats, which is an ecologically sensitive region. The drainage areas of Papanasam and Manimuthar watersheds are 163 and 211 km2, respectively and they show patterns of dendritic to sub-dendritic drainage. The slope of both watersheds varied from 0 to 59 and 0 to 55, respectively. Moreover, the slope variation is chiefly controlled by the local geology and erosion cycles. Each watershed was classified as a fifth-order drainage basin. The stream order of the basin was predominantly controlled by physiographic and structural conditions. The increase in stream length ratio from lower to higher order suggests that the study area has reached a mature geomorphic stage. The development of stream segments is affected by rainfall and local lithology of the watersheds.
The quantitative analysis of the watershedis vital to understand the hydrological setup of any terrain. The present study deals with quantitative evaluation of Swarnrekha Watershed, Madhya Pradesh, India based on IRS satellite data and SRTM DEM. Morphometric parameters of the watershed were evaluated by computations of linear and areal aspect using standard methodology in GIS environment. ARC GIS software was utilized for morphometric component analysis and delineation of the watershed using SRTM digital elevation model (DEM). The watershed is drained by a fifth-order river and shown a dendritic drainage pattern, which is a sign of the homogeneity in texture and lack of structural control. The drainage density in the area has been found to be low which indicates that the area possesses highly permeable soils and low relief. The bifurcation ratio varies from 3.00 to 5.60 and elongation ratio is 0.518 which reveals that the basin belongs to the elongated shape basin and has the potential for water management. The main objective of the paper is to extract the morphometric parameters of the watershed and their relevance in water resource evaluation management. The results observed from this work would be useful in categorization of watershed for future water management and selection recharge structure in the area.

The quantitative analysis of the watershed is vital to understand the hydrological structure of any topography. The present study deals with quantitative assessment of Manair Basin, Telangana, India, based on IRS LISS III satellite data and Cartosat DEM 30m resolution data. Morphometric parameters of the watershed were assessed by computations of linear and areal aspect using standard methodology in GIS environment. ARC GIS software was utilized for morphometric component study and delineation of the watershed using Cartosat digital elevation model (DEM). In this study, the Manair basin, tributaries of Godavari River, has been selected for thorough morphometric analysis. The drainage area of the basin is 6668.76 km2 and shows sub-dendritic to dendritic drainage pattern. The study area is designated as Fifth order basin with the drainage density value being as 0.41 km/km2. Three sub-watersheds Upper Manair, Mid Manair and Lower Manair are also delineated within this basin to calculate the selected morphometric parameters, e.g., stream order, stream length, bifurcation ratio, drainage density, drainage frequency, drainage texture, form factor, circularity ratio, elongation ratio, etc. and their hydrological implications were discussed. The generated database of morphometric parameters can provide scientific material for site selection of water-harvesting structures and flood management activities in the basin. The results observed from this work would also be useful in classification of watershed for future water management.
