Hydromorphogeological Microzonation to Infer Groundwater Potential and Quality

Multi-sensor satellite data integrated with Global Positioning System enabled geophysical and geochemical information has the potential to infer the availability and quality of groundwater in metamorphic Aravali formation of National Capital Region. Surface manifestation of satellite data has the potential to infer subsurface geology as well as soil moisture in weathered aquifer material. Normalized Difference Vegetation Index computed from the vegetation above the inferred lineament has the potential to infer groundwater quality. Electrical resistivity, X-Ray diffraction (XRD) and Induced Couple Plasma Emission Spectrophotometer (ICPES) analysis further support the spectral reflectance anomaly in litho units. Deep seated fractures with interconnected morphological manifestation have been inferred by using Proton Precession Magnetometer anomaly data. Although it was not possible to infer very deep seated potential fractures by using satellite data but the accurate ground truthing by geophysical investigations has been used to provide a clear hydromorphogeological attribute of potential aquifers. Drilling litho logs supported by thin section petrography suggests that high grade metamorphism is suggestive of good fractures in quartzite-schist-granite-pegmatite terrain of Aravali formation o
