Saumitra Mukherjee School of Environmental Sciences Jawaharlal Nehru University New Delhi, India ABSTRACT Information on land use patterns and changes are required for planning, utilization, and implementation of groundwater exploration and rainwater harvesting. Multispectral and multitemporal satellite data has the potential to delineate sites for water resource management. Magnetic and resistivity surveys can further confirm subsurface aquifer configuration. Due to heterogeneity of aquifer materials, it is essential to take a holistic approach that includes geological information supplemented with remotely sensed data and supported by resistivity and magnetic anomaly detection. This approach is used for locations of higher spectral reflectance and lineament density which are assumed to be areas of aquifer recharge. This investigation focussed on the Aravali quartzite terrain of Delhi, India at the Research and Referral Hospital and Jawaharlal Nehru University areas. Suitable areas are identified for construction of check dams, roof-top rainwater harvesting pits, and drilling sites in the difficult terrain of the Aravali quartzite. Reference: Mukherjee, S., S.
