Description
Summary:In the present scenario, groundwater resources are becoming scarce and there is need of identifying additional resources to meet the future demands in the study area. The present study focuses on groundwater prospecting using geographic information system-based analytical hierarchical process and geophysical tests. Hierarchical process was used to determine and assign weights to the themes for demarcating groundwater potential zones in the Cheyyeru watershed. Study revealed that, in the study area, Cheyyeru watershed, 261.70 (36.15%), 210.05 (29.01%) and 252.25 (34.84%) km2 of area has good, moderate and poor groundwater potential, respectively. Results also indicated that Gundlur, Rayavaram and Baddanagadda have good, moderate and low potentials, respectively. Reliability of results was ascertained using groundwater yield data and vertical electrical sounding data from 13 pumping wells and 9 locations, respectively. Methodology adopted in this study is more systematic, reliable and accurate. Same can be adopted while carrying out similar works for better planning, conjunctive use and development of groundwater resources in the basin.
