Morphometric Analysis Of Surface Water Bodies

Multi temporal satellite data is utilized for extraction annual water spread areas of respective surface water bodies in the few selected mandals of Medak District of Telangana State, India. A composite land use land cover map of the study area was also prepared to understand the cropping pattern under each tank command.Morphometric analysis was carried out based on Digital Elevation Model derived slope, aspect, and drainage pattern. Further geology of the study area was carried out and is found that the Basalts of Deccan plateau are in the contact with the granitic/gneiss of the study area. Based on drainage pattern it is observed that areas covered by basalts are found to be diverging with poor to nil presence of surface water bodies. Analysis of metrological data depicts high annual temperatures in the basaltic terrain and decreased in granitic terrain. Annual average rainfall is found to be excess in the Alladurg Mandal corresponding to good yields in ground water resources.
