A GIS- Based suitability analysis for siting a solid waste in an urban area

Locating an appropriate solid waste disposal site has been a major problem in the municipal environment. The use of landfills is the most economical and environmentally acceptable method for the disposal of solid waste all over the world. The analysis of spatial data and consideration of the regulation and accepted criteria are part of the important elements in the site selection. The aim of this paper is to show how application of geographic information system helps in locating solid waste disposal in Abadan city. In this paper, the types of suitable soil for solid waste disposals, land use/ land cover, transportation routes and proximity to surface water are thoroughly studied. Relative importance weight of each criteria in the geographic information system and Analytic hierarchy process was determined and finally the suitability map was prepared. Based on the final suitability map, appropriate solid waste landfill site was located in the northeast part of the study area. Select the best landfill site among the candidate ones, and the output results can enable decision makers to make appropriate decisions to reduce the costs both in economic and environmental criteria.
