Abstract: (3144 Views)
Background and Aim: Landfill site selection is a complex process that includes many parameters such as social, economic, environmental and governmental regulations that need to be managed, and has been introduced as an important challenge of urban management all around the world. Using spatial data and appropriate analysis of them is very important in locating landfills.
Material and Method: This study was performed in order to select the best location for a landfill by using multi- criteria analysis and in accordance with environmental regulations. The complexity and frequency of effective factors in determining the landfill site location led us to use GIS in land allocation problems. After identifying the required criteria and indicators, maps and descriptive data were prepared. Then by using an Ordered Weighted Averaging (OWA) process, a multi-criteria evaluation model was developed in the form of 6 scenarios. In this regard, by eliminating constraints, the standardization of factors was done by fuzzy membership functions in byte scale; and finally, Analytical Hierarchy Process (AHP) and Zonal Land Suitability (ZLS) were used to weigh the factors and site selection, respectively.
Results: The results showed that just 0.13 percent of the area is suitable for landfill that was located in the central part. Finally, 4 sites were selected for landfill location, which site number 1 is suitable for landfilling for up to ten years and site number 2 for the upcoming twenty years.
Conclusion: It can be concluded that the site dare Smaghan is not suitable for landfill, based on environmental criteria.
