Due to the outdated methods of common landfill selection it is imperative to reevaluate the usage suitability. This study aims to assess the suitability of the existing waste landfill located 2 km east of Qeydar, Iran. We have used a combination of Geographic Information System (GIS) and Analytical Hierarchy Process (AHP) along with fieldwork surveys to assist us in achieving this goal. Diverse climatological, geological hydrological, environmental and socio-economical data were collected and analyzed. Subsequent to data base preparation, three major criteria and 11 sub- criteria were considered based on local legislations and data availability. Raster maps of the sub-criteria were prepared and transformed into 0 to 1 standard scale. Subsequently, AHP was applied to assign the relative importance weights of criteria and sub-criteria to each other. Finally, a landfill suitability map was generated and the study area was ranked based on final suitability scores. Based on the final suitability map, the unsuitable areas for the landfill are located around North and middle part of the plain. By contrast, the most suitable areas for landfill sittings are located mostly in South, parts of the studied area. The results indicate that the present landfill is situated in a unsuitable category.
