Zonation of Lorestan Province for Sanitary Landfill Site Suitability

Though there are several alternatives to solid waste disposal, including the sanitary landfill method, the incineration method, the composting method and anaerobic digestion, but disposing of waste in a landfill is the most traditional method of disposal of solid wastes, and it is a common practice in most developed countries. Several techniques and methods have been used in a sanitary landfill site selection in the literature. In this paper three methods consist of a simple additive weighting method, fuzzy based method and Neuro - Fuzzy hybrid method has been used to landfill site selection in Lorestan province and the results of three methods have been compared to each other. The prepared maps by means of simple additive weighting and fuzzy methods have a correlation with the real condition of ground of 43 and 65 percent, respectively, whereas the Neuro - Fuzzy method map has a 55 percent correlation with field observation.
