COCKPIT-PLUS: A proposed method for rapid groundwater vulnerability-driven land use zoning in tropical cockpit karst areas

Geography and Sustainability, 2023
Karst groundwater is highly vulnerable to contamination, which urges better land use zoning. This paper proposes a new approach, called COCKPIT-PLUS, to minimize groundwater contamination within cockpit karst regions. The method employed four parameters:
