“…The bifurcation ratio is dimension less property and generally ranges from 3.0 to 5.0. The lower values of Rb are characteristics of the sub-watershed, which have suffered less structural disturbances (Strahler, 1964) and the drainage pattern has not been distorted because of the structural disturbances (Nag, 1998). In the present study, the higher values of Rb indicate strong structural control on the drainage pattern.…”

In this study, an attempt has been made to understand the morphometric characteristics of surrounding of Paras thermal power plant, using remote sensing and GIS techniques. The main objective of this study is to give priority for river sub-watershed (P-17) development by determining the morphometric parameters. This study involves drainage network delineation and morphometric parameters determination, using onscreen digitization on 1:50,000 topographic maps through GIS environs.

“…These differences are depending upon the geological and lithological development of the drainage basin (Strahler, 1964). In the study area, the higher values of Rb indicate a strong structural control in the drainage pattern whereas the lower values indicate that the sub-basins are less affected by structural disturbances (Strahler, A.N., 1964;Nag, 1998;Vittala et al, 2004;Chopra et al, 2005). The Rb values in the sub basins of the study area range from 0.11 to 20.75 indicating that all the sub-basins are falling under regular basin category.…”

The study area covers 1026 sq km comprising of 15 sub-watersheds, namely Saggiyam (SB-1), Mudoldoddi (SB-2), Halgapuram (SB-3), Deverabetta (SB-4), Mattugaudanadoddi (SB-5), Handgalli (SB-6), Manchepura (SB-7), Lokkanahalli (SB-8), Chinchalli (SB-9), Prakash palya (SB-10), Naripura (SB-11), Adugulpodu (SB-12), Ramayanadoddi (SB-13), Jodukara hatti (SB-14), Depudisahibradoddi (SB-15) which range in area from 16.87 to 180.02 sq km. Different morphometric parameters were evaluated to understand the drainage characteristics. The drainage pattern of these sub basins have been delineated using Geocoded FCC bands 2, 3 and 4, of IRS 1C and 1D (LISS 111+ PAN merged) on 1:50,000 scale and Survey of India Toposheets as reference. The morphometric parameters are computed using Arc Info and Arc View GIS software's. The drainage pattern of the study has shown dendritic to sub-dendritic drainage pattern with stream orders ranging from 4th to 5th order. The Drainage density ranges from 1.51 to 4.83 km/km 2 suggesting coarse to moderate drainage texture.The change in values of stream length ratio indicates their late youth stage of geomorphic development. The values of bifurcation ratio are ranging from 0.11 to 20.75 indicating that the study area is having strong structural control over the drainage pattern and all the sub basins fall under normal basin category. The values of form factor and circulatory ratio, suggest that the sub basins are elongated to circular in shape. Geographic Information System, when used with satellite images, could help in determining the morphometric parameters of watershed and river basins. It is concluded that remote sensing ground and GIS have been proved to be efficient tools in drainage delineation and updation.

“…These irregularities are dependent upon the geological and lithological development of the drainage basin (Strahler, 1964). The lower values of R b are characteristics of the watersheds, which have suffered less structural disturbances (Strahler, 1964) and the drainage pattern has not been distorted because of the structural disturbances (Nag, 1998). Whereas, higher bifurcation ratio results in large variation of frequencies between successive orders and indicates a mature topography (Sreedevi et al, 2004).…”

“…The image interpretation techniques are less time consuming than the ground surveys, which if coupled with limited field checks, yield valuable results. Many researchers like Srivastava (1997), Nag (1998) have carried out morphometric analysis using Remote Sensing techniques. In the present study, Remote sensing data has been used in GIS platform to have the morphometric study of a watershed of semi-arid (khad) region located in Hoshiarpur district of Punjab (India).…”

In the present study an attempt has been made to study the morphometric parameters and drainage properties of a watershed of semi-arid (khad) region located at Hoshiarpur district of Punjab (India). Morphometric analysis has been carried out on the watershed of 174.385 km 2 area using ESRI Arc GIS 10.0 software and CartoSAT-1 DEM data of spatial resolution 2.5 m obtained from NRSC (National Remote Sensing Center), Hyderabad for evaluating various morphometric parameters. On the basis of linear, areal and relief aspects various morphometric parameters were evaluated using Arc GIS 10.0 software. Hydrology tool under Spatial analyst tool in ArcGIS10.0 has been used for generating the watershed boundary, flow accumulation, drainage network and stream order map. Area and the perimeter have been calculated using ArcGIS 10.0 and it comes out to be 174.385 Km 2 and 77.539 km respectively. Drainage map of the study area shows dendritic to sub-dendritic drainage pattern. The study reveals that the stream number decreases with the increase in the stream order, the mean bifurcation ratio of the watershed is 4.35 which means that the watershed falls under normal basin category, the elongation ratio of the watershed is 0.604 which indicates that it is less elongated, the circularity ratio of the watershed is 0.365 indicating its elongation and highly permeable homogeneous materials. The present study shows the competency of remotely sensed satellite imagery coupled with GIS for morphometric analysis of a particular region and is useful for the watershed management, identification of critical zones and for implementing various soil and water conservation practices in that region or watershed.
