Descriptif
The investigations carried out in the study area include intensive field work, laboratory studies and interpretation of satellite imageries of the study area and collection and processing of published and unpublished data available. A brief description on soil types and geology of the area is given and the geological map of the area is prepared. Drainage network of the Peddavanka watershed area was studied by undertaking the morphometric analyses using the Survey of India Topographic sheets on 1:50,000 scale by adopting the methods given by Horton (1932), Strahler (1952), and Schumm (1956). Data on climate was collected and the elements analysed and water balance based on climate indices are computed and finally the relevant graphs were prepared to estimate the water balance after the method of Tllornthwaite and Mather (1957). The geomorphological features are identified and the geomorphological and structural map of the area are prepared after field checks based on remote sensing data. The aquifer parameters like transmissibility, storage co-efficient and specific capacity are computed from the data obtained from pump tests after Slichter (1906) and Papadopulos and Cooper (1 967). The sub-surface structures of the watershed area was studied by preparing graphs and 3D diagrams from the resistivity data obtained by following Schlumberger method and curve matching technique (Orellana and Mooney, 1966). Hydrochemistry was also undertaken by collecting 76 water samples in both the seasons to rate their utility and suitability for irrigation and public supplies by adopting the latest methods of analyses. Finally based on the results of exploration and budget analyses a number of remedial measures are recominended for the overall development of the study area.
