GIS-Based Groundwater Vulnerability Mapping of Gully Erosion-Prone Areas in South-Eastern Nigeria

Okafor, Brian O., Umeghalu, Christian O., Eyibara, Oghenehokoke U. & Okpoji, Awajiiroijana U · Asian Journal of Chemical Sciences · 2026

Groundwater resources in South-Eastern Nigeria are increasingly threatened by accelerated gully erosion, intense seasonal rainfall, rapid urbanisation, and unsustainable land-use practices, all of which increase aquifer susceptibility to contamination. This study assessed groundw...
