Geological and Hydrogeological Layers

The Aquifers, Lithology, and Lineament dataset, part of the CoRE Stack, integrates India’s hydrogeological framework by mapping aquifer systems, geological formations, and structural lineaments. Together, these layers provide a comprehensive understanding of groundwater occurrence, recharge potential, subsurface flow pathways, and overall hydrogeological conditions, supporting groundwater assessment, planning, and sustainable resource management.

About Dataset

The Aquifers, Lithology, and Lineament dataset, part of the CoRE Stack (Commoning for Resilience and Equality), integrates India’s key hydrogeological layers to provide a comprehensive understanding of subsurface water systems. It brings together delineations of aquifer types and extents, lithological formations that shape groundwater occurrence and recharge characteristics, and linear geological structures—such as faults and fractures—that govern groundwater flow and aquifer connectivity. Combined, these datasets support assessment of groundwater potential, recharge behavior, subsurface storage, and geohydrological vulnerability. They enable integrated modeling and planning when used alongside groundwater levels, extraction stages, and other hydrological datasets in the CoRE Stack. This consolidated framework helps planners, researchers, and communities understand subsurface conditions and design sustainable groundwater development, recharge interventions, and ecosystem management strategies.

Technical details and methodologies are available in the CoRE Stack Technical Manual: https://core-stack.org/core-stack-technical-manual-v2/

Purpose of Dataset

The Purpose Of The Aquifers, Lithology, And Lineament Dataset Is To Provide An Integrated Hydrogeological Framework For Understanding India’s Subsurface Water Systems. By Combining Aquifer Extents, Geological Formations, And Structural Lineaments, The Dataset Supports Assessment Of Groundwater Potential, Recharge Pathways, And Geohydrological Vulnerability. Used With Other Core Stack Layers, It Enables Informed Groundwater Planning, Site Selection For Recharge And Extraction, And Resilient Water Resource Management.
