In vestigation of effective climatic factors in landfill sites selection in shabestar in GIS environment

At present in many of developing countries, because of increased consumpting of different natural and man- made composite resources particularly in urban areas, a quantity of enormous garbage and other waste materials are being produced. Shabestar city, with mor than one million residents as a metroropoliton in dustrial area which is located in the northwest of iran, has been not nonetheless equipped with an organized varage system. During the last decades, garbage and other refused n\materials were mostly discarded in outside of the city without applying any specific managed strategy. Such unreasonable procedure could cause many environmental damages and conquently introducing a number of associated diseases in the context of study area. Accordigly, the main objective of the current investingation was to the spatial analysis procedures in selecting of an appropriate dumping site, Reaching the study purpose, in the first stage, all important topo-climatic and concerned ecological obserrations were collected to the Microsoft Office Access to accomplish an inclusive database of the study area. In the seconds stage, all spatial date layers were weighted and categorized according to well-known standards the the EDRISI soft ware package. Subsequently, four dissimilar multicriteria Desison Analysis(MCDM) algorithms such as: Boolean, Analytic Hierarchy process(AHP), and simple Additive Weighting(SAW) have been progressively applied to the date in the ARC GIS setting. Concurrent analyzing of revealed models and ground control points(GCP) confirm that the Boolean method is not accurately demonstrated a suitable landfill spot. Also, an exact examination of AHP model shows a few uncertainties on the associated result. Howerer, maps created by applying of SAW algorithms could been tirely trusted regarding very small variations on their spatial sites. Therfore, an overlaying technique was applied to all comman suitable parts-exposed by AHP and SAW models- to locate the final proper waste dumping site, which positioned somewhere in the northwest of the region. An initial calculation confines that the selected geographical location, with 10 hectares areas possibly will support remoral of 100 tone(on a daily basis) garbage for the next 15 years.
