The framework provides local authorities with a practical tool for flood disaster planning and risk reduction.
Groundwater Vulnerability Assessment to Cemeteries Pollution through GIS-Based DRASTIC Index
Researchers used geographic information system (GIS) tools and the DRASTIC index to assess how vulnerable groundwater is to pollution from cemeteries. The study mapped areas where burial practices could allow contaminants from decomposing materials to reach underground water sources. The findings provide a framework for evaluating environmental risks associated with cemetery locations and protecting drinking water resources.
