Abstract :
Selecting the appropriate site landfill is one of the important steps in the management of municipal solid waste. Given the devastating environmental, economic, and ecological impacts of municipal waste, landfill selection must be carefully and scientifically processed. New tools and technology can help find the right place for a landfill. Geographic information systems (GIS) are nowadays widely used in environmental planning. In this study, different parameters such as lithology, land use, vegetation, soil properties, topography (slope), distance from urban areas, distance from main road, main waterways Suburbs, residential areas, wells and aqueducts and faults in order to determine suitable location for solid waste landfill in oshnavyeh city have been considered. Next, the paired comparison matrix was developed using AHP method and the final weights of each data layer were calculated using Expert Choice 11 software and in GIS environment, modeling was performed by hierarchical analysis process. Finally, landfill sites in oshnavyeh city were identified in four floor as Quite suitable, suitable, relatively suitable and inadequate based on their location ability.
