| Summary: | Solid waste landfill site selection is a
relatively complex process and depends on several criteria and official
regulations. In this study, the suitability of solid waste landfill site
selection for the city of Elazığ, Turkey, was determined by Multi-Criteria
Decision Analysis (MCDA) and Geographic Information Systems (GIS). For this
purpose, nine different criteria, namely distance from residential areas,
distance from roads, distance from rivers, distance from spring wells, geology,
slope, aspect, land capability classification and land use, were taken into
consideration and their degrees of relative importance were defined via MCDA
and the schematic maps for each criterion were prepared with GIS applications.
The final landfill site suitability map for the study area was obtained by the
overlay analysis tool of ArcGIS 9.3. The study results reveal that the landfill
suitability index values for the selected site range between 2.64 and 6.10. The
major part of the landfill site has relatively low index values implying that
the selected site is suitable for solid waste landfill. |
