Morphometric Analysis of Panzara River Basin Watershed, Maharashtra, India Using Geospatial Approach
2024
This work aims to deal with the morphometric analysis of the Panzara River Basin (PRB) watershed, a tributary of the Tapi River in Maharashtra, India. In this study, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Digital Elevation Model (DEM) and Survey of India (SOI) toposheets have been used along with various parameters like linear, areal, and relief aspects in Geographical Information System (GIS) environment. Out of total 293 number of streams in the watershed, 226, 54, 12, and 1 are of first, second, third and fourth orders respectively. PRB watershed is of 4th order and less elongated in shape, having lower peak flows of longer duration with dendritic pattern and having coarse drainage texture. The bifurcation ratio lies between 6 and 7, indicating that geological structure doesn't have more influence on drainage patterns. The area forms a rugged topography having an elevation range from 123 to 1199 m above Mean Sea Level (MSL). Variables like Stream Frequency and Drainage Density shows impermeable surface of PRB watershed which causes higher water discharge volume and speed in the basin so that the probability is maximum for frequent floods. The results indicates that PRB is having high slope in SW part as compare to NE part and having very low gradient ratio. These variables also shows a temporal variation in the water flowing speed in the stream when the flood reaches its peak. The outcomes of this work can suggest and recommend a better mechanism for proper watershed management in the PRB.
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.
Morphometric Investigation of Morna River Basin, Maharashtra, India using Geospatial Techniques
Nowadays river systems consisting with uneven number of natural resources face different problems with a large population pressure and climate change. To overcome such problems, the river basins must monitor properly using advanced technologies. In the present research work, an effort verifying the detailed morphometric characteristics of Morna river is undertaken which itself is a part of Warna basin of Maharashtra. A morphometric analysis of Morna river proceeds using geospatial techniques. The purpose of assimilation of morphological features and analyzing properties of basins can be done by using GIS and image processing techniques. Linear and areal aspects of morphometric parameters can be evaluated using GIS. The present task copes mainly with morphometric parameters such as stream order, stream length, bifurcation ratio, drainage density, stream frequency, texture ratio, elongation ratio, circularity ratio and form factor ratio etc. For the preparation of DEM, Cartosat data can be used; whereas for the evaluation of linear, areal and relief aspects of morphometric parameters GIS technique can be taken into consideration. The Morna river basin is estimated to have an area of 172.2 km 2. The study area was concerned with 1 st to 6 th stream orders. There are altogether 449 streams with a total stream length of 395.25km. Present research work is useful to understand the topography, erosional status and drainage pattern of the area and also for constructing a comprehensive watershed development plan. This study plays an important role in planning rainwater harvesting and watershed management also.
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.

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.

Remote sensing and geographic information system (GIS) are two of the most important tools used to evaluate the morphometric characteristics of watersheds, as morphometric analysis of river basins using conventional methods, is very time to consume, laborious and cumbersome. In this study, the morphometric characteristics of the Adula watershed were calculated using ESRI- ArcGIS. The areal extent of the Adula watershed varies between 19°32’40” N to 19°43’2” N latitude and 74°10’15” E to 74°48’18” E longitude. The topographic sheets obtained from the survey of India on a scale of 1:50000 and the SRTM (Spectral Radar Topographic Mission) Digital Elevation Model of 30 m resolution, were used for watershed delineation and deriving the linear (stream order, stream number, bifurcation ratio), aerial (basin area, basin perimeter, drainage density, form factor, stream frequency, and circulatory ratio), relief (height of outlet of watershed, basin relief, maximum height of watershed, total ...
Watershed management has gained importance in management of natural resources, such as soil, water their conservation and improvement in the livelihood of the peoples in the region. Morphometric analysis has been commonly applied to prioritization of watersheds arresting the loss of soil and water. In the present study an attempt has been made to study the morphometric characteristics of Chanavada micro watershed using remote sensing and GIS technique. The Chanavada micro-watershed is part of Jhakham, Gomti catchment covering an area of 1475 ha in Girwa block of Udaipur district in southern Rajasthan. The morphometric analysis of the watershed reveals that the watershed is 4 th order, elongated in shape having mixed drainage pattern. The value of mean stream length (Lsm) varies from 0.59 to 8.67 may be due to variation in slope and topography. The stream length ratio showed an increasing trend in the length ratio from lower order to higher order indicating their mature geomorphic stage. The high value of bifurcation ratio indicates the strong structural control on the drainage development. The drainage density of the watershed is 4.16 which could be the result of impermeable sub-surface material, sparse vegetation and mountainous relief and drainage texture of the watershed lie between 2 and 4 which is related to coarse texture. The low Rf value (0.23) indicated elongated shape of watershed and suggesting flatter peak flow for longer duration. The value of elongation ratio (Re) is associated with high relief and steep slope showing elongated shape of watershed. The present study demonstrates the utility of remote sensing and GIS technique in studying morphometric analysis of hilly watershed.
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 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. Shaliganga Sub catchment comprises of two watersheds with a total area of 354 km² and has been selected for the present study. 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 Sub catchment were computed at watershed level. This was achieved using GIS to provide digital data that can be used for different calculations
