Abstract	Landfill siting is one of the most important concerns for city planners particularly in regions with intensive land uses. This paper addresses a landfill site selection methodology that integrates GIS and AHP with expert opinion analysis. It employs two stages to select most suitable landfill site for Ramjerd city, Fars province, Iran. First, the desired thematic maps of the study areas were prepared to establish a GIS database for municipal landfill site selection. Thereafter, unsuitable areas were masked based on Iran environmental protection organization legislations. The obtained Boolean map shows almost 99 percent of the study region is unsuitable for landfill construction due to shallow groundwater and intensive land use. At the second stage, the obtained nine candidate sites at preliminary siting stage were ranked by AHP method. The evaluation criteria were derived by face-to-face interviews of several experts. Subsequently, three factors including potential of surface water contamination, land use and wind direction that had spatial variability among alternatives, were selected. Ranking of alternatives with respect to these factors was performed by Ramjerd municipality stakeholders opinion. The reliability of the results was examined by applying sensitivity analysis. The results obtained based on proposed method were verified by comprehensive field visit of three top ranked alternatives. This field visit confirmed that combination of GIS and AHP can make the best time-saving and flexible method to support decision makers in solving complicated landfill site selection problem. The main objective of this study was to find a best location for municipal solid waste disposal by integrating GIS and AHP features.
