The IRS -P6 LISS-IV satellite data is used to demarcate Hydrogeomorphology land forms and lineaments on 1;10000 scale to evaluate groundwater potential of the study area. The Ramannapet Mandal area of Musi river basin is occupied mostly by hard rock they are granites and gneisses of Archaean age with intrusive bodies of dolerites, and of the portion of the study area is covered mainly by both wet and dry cultivation. The major geomorphic unit identified in the area are, Denudational hills, Residual hills, Inselbergs, Dykes, Pediment inselberg complex, Pediment, Pediplain and valleys. Most part of the study area is occupied by Pediplain with various thickness and the groundwater potential is directly related to thickness of Pediplain.
The object of the study is Remote Sensing imagery with its synoptic coverage acts as a tool for finding suitable solution when combined with conventional data. Hydro-geomorphic maps were prepared by integrating the Lithology, landforms, and structural fabric and hydrology layers and drainage layers using Remote Sensing and GIS techniques, the scale range of 1: 10,000. The lineament density map was generated in GIS software using Kriging method (Sabins, F. F., (1997).
Outcomes of the study Based on visual interpretation and field investigations the different types of hydro geomorphic units observed in the study area. The recent alluvium deposits are present along the stream courses. Field observations shows that groundwater occurs under unconfined conditions with water table shallow to deep depth. from the lineament density and lineament intersection maps prepared to understand the impact on groundwater percolation. Finally, Hydrogeomorphology and lineament maps area overlaid following the weighted index overlay method, which delineate groundwater potential zones. an integrated Remote sensing and GIS based approach has been used for demarcating groundwater potential zones in the study area.
The study area Ramannapet Mandal is in northern part of the district of Nalgonda, Telangana State, India. The study area people occupation is agricultural, and poultry, 80 percent of the people depending only agricultural activity
