 ABSTRACT

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 (90m 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. Such as areal parameters: viz: Infiltration number, length of overland flow, circularity ratio, elongation ratio, form factor, lemniscates ratio, fitness ratio for both catchments were determined using ArcGIS.

Key words: Infiltration number, Length of overland flow, Circularity ratio, Elongation ratio, form factor, Lemniscates ratio, Fitness ratio
