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.

In the present paper, an attempt has been made to study the detail morphometric characteristics of Karawan watershed in Dhasan basin, which itself is part of the mega Yamuna basin in Sagar district, Madhya Pradesh. For detailed study, we used ASTER data for preparing digital elevation model (DEM), and geographical information system (GIS) was used in evaluation of linear, areal and relief aspects of morphometric parameters. Watershed boundary, flow accumulation, flow direction, flow length, stream ordering have been prepared using ArcHydro Tool; and contour, slope-aspect, hillshade have been prepared using Surface Tool in ArcGIS-10 software, and ASTER (DEM). Different thematic maps i.e. drainage density, slope, relief, superimposed profile, and longitudinal profiles have been prepared by using ArcGIS software. Authors have computed more than 85 morphometric parameter of all aspects. Based on all morphometric parameters analysis; that the erosional development of the area by the streams has progressed well beyond maturity and that lithology has had an influence in the drainage development. These studies are very useful for planning rainwater harvesting and watershed management.
The quantitative analysis of drainage system is an important aspect of characterization of watersheds. Using watershed as a basin unit in morphometric analysis is the most logical choice because all hydrological and geomorphic processes occur within the watershed. The Budigere Amanikere watershed a tributary of Dakshina Pinakini River has been selected for case illustration. Geoinformatics module consisting of ArcGIS 10.3v and Cartosat-1 Digital Elevation Model (DEM) version 1 of resolution 1 arc Sec (*32 m) data obtained from Bhuvan is effectively used. Sheet and gully erosion are identified in parts of the study area. Slope in the watershed indicating moderate to least runoff and negligible soil loss condition. Third and fourth-order sub-watershed analysis is carried out. Mean bifurcation ratio (R b) 3.6 specify there is no dominant influence of geology and structures, low drainage density (D d) 1.12 and low stream frequency (F s) 1.17 implies highly infiltration subsoil material and low runoff, infiltration number (I f)1.3 implies higher infiltration capacity, coarse drainage texture (T) 3.40 shows high permeable subsoil, length of overland flow (L g) 0.45 indicates under very less structural disturbances, less runoff conditions, constant of channel maintenance (C) 0.9 indicates higher permeability of subsoil, elongation ratio (R e) 0.58, circularity ratio (R c) 0.75 and form factor (R f) 0.26 signifies sub-circular to more elongated basin with high infiltration with low runoff. It was observed from the hypsometric curves and hypsometric integral values of the watershed along with their sub basins that the drainage system is attaining a mature stage of geomorphic development. Additionally, Hypsometric curve and hypsometric integral value proves that the infiltration capacity is high as well as runoff is low in the watershed. Thus, these mor-mometric analyses can be used as an estimator of erosion status of watersheds leading to prioritization for taking up soil and water conservation measures.

A GIS-based morphometric analysis of Kandaihimmat watershed, Hoshangabad district, M.P. India
2018
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...
The accurate delineation of the catchment boundaries is the first important step in the determination of catchment geometry and extraction of stream network for morphometric analysis. Morphometric analysis were carried out for Karabayyanahalli sub-watershed in Karnataka state from three different sources viz., Cartosat DEM (30m), SRTM DEM (90m) and SOI topographic maps (1:50,000). Different morphometric parameters are derived from these three data are evaluated to examine the difference within the results for the planning and management of micro watershed in the study area. Drainages are extracted from the DEM by using Archydro tool in ArcGIS 9.3 version. The drainage networks are digitized from SOI toposheet. The flow of water from higher to lower elevation and steepest descent in a pixel are considered for the extraction of drainages from DEM. Result from SOI topographic maps are more or less correlated with Cartosat DEM data. SRTM data shows less drainage density and frequency compared to Cartosat DEM and SOI toposheet. The shape parameters from all the three data show the subwatershed is oval in shape. The results shows that the morphometric parameters derived from Cartosat DEM data provide good and satisfactory information about the catchment characteristics and it also reveals that accuracy of the watershed
Morphometric analysis of a watershed of South India using SRTM data and GIS
Journal of the Geological Society of India, 2009
An attempt has been made to study drainage morphometry and its influence on hydrology of Wailapalli watershed, South India. For detailed study we used Shuttle Radar Topographic Mission (SRTM) data for preparing Digital Elevation Model (DEM), aspect grid and slope maps, Geographical information system (GIS) was used in evaluation of linear, areal and relief aspects of morphometric parameters. The study reveals that the elongated shape of the basin is mainly due to the guiding effect of thrusting and faulting. The lower order streams are mostly dominating the basin. The development of stream segments in the basin area is more or less affected by rainfall. The mean Rb of the entire basin is 3.89 which indicate that the drainage pattern is not much influenced by geological structures. Relief ratio indicates that the discharge capability of these watersheds is very high and the groundwater potential is meager. These studies are very useful for planning rainwater harvesting and watershed management.
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.
In the present paper, an attempt has been made to study the Morphometric characteristic of a Semi Urban watershed, trans Yamuna at Allahabad, Uttar Pradesh, India. For detail study Survey of India toposheets at 1:50,000 scale and CartoSAT-1 DEM data with 30m spatial resolutions has been used. Watershed boundary, flow accumulation, stream number, stream ordering, stream length have been prepared using ArcGIS 9.3, Hydrotool. It has been found that the total length of all stream segments under stream order I to VIII is 266.38,88.15,39.17,17.17,10.62,4.0,4.7,0.2 Km respectively. The total length of Streams for the entire watershed has thus been found to be 430.39 Kms representing a dense drainage network. More than ten morphometric parameters of all aspects have been analysis. This study is very useful for planning rain water harvesting and watershed management.
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.
