tailieunhanh - Geomorphometric analysis of osman sagar and himayat sagar catchment using remote sensing and GIS

In the present study, analysis of geomorphometric characteristics of osman sagar and Himayat sagar catchment was carried out using remote sensing and GIS and the drainage networks of the both the catchment were generated using SRTM DEM (90 m resolutions). Two adjacent catchments, Himayath sagar and Osman sagar, located Rangareddy district of Telangana state, India were selected for study. Morphometric features and drainage network of Himayath sagar and Osman sagar catchments were extracted from DEM using ArcGIS software. | Geomorphometric analysis of osman sagar and himayat sagar catchment using remote sensing and GIS (2020) 9(3): 786-796 International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 3 (2020) Journal homepage: Original Research Article Geomorphometric Analysis of Osman Sagar and Himayat Sagar Catchment Using Remote Sensing and GIS N.

Two adjacent catchments, Stream length ratio, Bifurcation Himayath sagar and Osman sagar, located Rangareddy district of ratio, Compactness Telangana state, India were selected for study. Morphometric features and coefficient and drainage network of Himayath sagar and Osman sagar catchments were Rho-coefficient extracted from DEM using ArcGIS software. Such as linear parameters viz, Article Info Stream order Stream number, basin length, mean stream length, stream Accepted: length ratio, bifurcation ratio, Compactness coefficient and Rho-coefficient 05 February 2020 for both catchments were .
