This research presents an integration of fuzzy logic with GIS for landfill site selection in Durood city alongside with the customized GIS application for doing this study. One of the most important issues of sanitary landfill is to identify suitable locations. Landfill selection in an area is a critical issue in the decision making process because of its great impact on the economy, ecology and the environmental health of the region. most common sub-criteria, documented in literature and implicated (IEPO) including surface water, ground water, land use, distance to well, soil type, slope, protected area, fault in environmental group, residential area, road, airport, village, infrastructure, historical area, wind direction in socioeconomical group were selected and the weight of each criterion was determined based on expert’s knowledge with use of analytical hierarchy process (AHP). At the first step, in order to find the suitable sites, GIS digital map overlay techniques were used (customized GIS application). The second step was a fuzzy logic approach that the system ranked sites on a scale of 0–100%, with 100% being the most appropriate one. At the third step the potential sites that were selected from the last step will be ranked by Analytical Hierarchy Process (AHP) in order to prioritize the potential sites. Field observations also confirmed suitability of the selected sites, and hence this method can be used in urban areas for waste dumping site selection procedure. Selected sites are considered to be suitable for landfill to minimize environmental risk and human health problems.
