A Gis Based Multi-Criteria (MCE) evaluation system for landfill site selection
Selecting the most suitable site for landfill can avoid any ecological and socio-economical effects. The increase in industrial and economical development along with the increase of population growth in Thessaloniki city (North Hellas) generates tremendous amount of solid waste within the region.
Factors such as the scarcity of land, life span of landfill, and environmental considerations warrant that the scientific and fundamental studies are carried in selecting the suitability of a landfill site.
The analysis of spatial data and consideration of regulations, and accepted criteria are part of the important elements in the site selection. In this study, candidate sites for an appropriate landfill location for the Thessaloniki Area municipal area are determined by integrating geographic information systems (GIS), Remote Sensing (RS), multi-criteria evaluation (MCE) analysis with Fuzzy Logic (FL) and Analytic Hierarchy Process (AHP).
To identify appropriate landfill sites, eight input map layers including proximity to urban areas, proximity to wells and water table depth, geology and topography, proximity to touristic and archeological sites, distance from roads network, distance from drainage networks, and land slope are used in constraint mapping.
A final map model was generated which identified potential areas showing suitability for the location of the landfill site.
