Abstract

The selection of a site for a new landfill is a complicated task because of social, geological, environmental, hydrological and economic issues. In this study we applied an optimized land use site selection based on overlay analysis using a Geographic Information System (GIS). Several important factors and criteria were considered, including terrain elevation, slope, depth to ground water, distance to surface water, site accessibility via the existing road network, and land use. Thematic maps of these criteria were developed and overlaid in a GIS to identify candidate locations for the landfill. The final site recommendation was selected from these candidates based on minimum site size and nearby population density. Our approach is unique because the environmental factors were considered as the primary governing factors, and the social parameter was only applied for the final selection of the candidate site.
