GIS-Based Groundwater Potential Mapping
Research Guide

What is GIS-Based Groundwater Potential Mapping?

GIS-Based Groundwater Potential Mapping integrates geospatial layers such as geology, land use, and hydrology within Geographic Information Systems to delineate high-yield aquifer zones using multi-criteria evaluation and overlay analysis.

This approach combines remote sensing data with GIS for groundwater exploration, zonation, and management. Key methods include Analytic Hierarchy Process (AHP), Multi-Influence Factor (MIF), and machine learning models like random forest. Over 10 highly cited papers since 2010 demonstrate its application, with Magesh et al. (2012) leading at 819 citations.

Key Challenges

Why It Matters

GIS-based mapping enables precise well site selection and sustainable extraction in water-scarce regions, reducing drilling failures by up to 70% as shown in semi-arid India studies (Machiwal et al., 2010). It supports watershed management by identifying recharge zones, critical for agriculture in areas like Tamil Nadu (Magesh et al., 2012) and Iran (Rahmati et al., 2014). Applications include flood hazard integration for holistic planning (Kazakis et al., 2015) and contamination risk assessment (Li et al., 2021).

Key Research Challenges

Data Quality Variability

Inconsistent resolution and accuracy of geospatial layers like geology and rainfall hinder reliable zonation (Magesh et al., 2012). Remote sensing data often requires preprocessing to align scales. This leads to uncertain potential maps in heterogeneous terrains.

Model Selection Uncertainty

Choosing between AHP, random forest, or evidential belief functions yields varying results across regions (Naghibi et al., 2015; Nampak et al., 2014). Validation against borehole yields remains inconsistent. Transferability to new watersheds is limited.

Integration of Hydrogeology

Linking surface GIS layers to subsurface aquifer dynamics challenges accurate prediction (Rahmati et al., 2014). Dynamic factors like recharge rates are hard to quantify. Climate change impacts on potential zones need better modeling.
