This document discusses micro-level aquifer mapping of the Palmakula-Kotur watershed in Andhra Pradesh. Various methods were used to map the aquifer geometry spatially and vertically, including geophysical VES surveys, hydrological data collection, and generating 2D and 3D GIS layers. The objectives were to decipher the aquifer geometry and disposition, generate micro-level aquifer maps, and characterize groundwater resources for planning and management. Contours and cross-sections show the subsurface geometry of multiple aquifers that varies spatially and with depth. Micro-level aquifer maps were prepared and contours show head disposition and groundwater flow directions. The results will aid groundwater resource management and development

Management
1. Different Hydro-Geomorphological units are demarcated with integration of Remote
Sensing and GIS data to field data.
2. With the Systematic vertical electrical sounding (VES) data 3-D water level map is
been created.
3. The Ground Water prospect has been determined through both the approach and
results are correlated to improve the ground water prospect Zonation .
