land fill site selection by using geographic information systems in urban areas

one of the serious and growing potential problems in most large urban areas is the shortage of land for waste disposal. although there are some efforts to reduce and recover the waste, disposal in landfills is still the most common method for waste destination. however, appropriate site selection for land filling is a problem in waste management and therefore needs to be addressed. an inappropriate landfill site may have negative environmental, economic and ecological impacts. therefore, it should be selected carefully by considering both regulations and constraints on other sources. this study aims to identify a suitable landfill site for waste disposal in malayer region. seven main criteria including geomorphology, geology, slope, distance from faults, settlement, streams and main roads were selected for this purpose and by performing multi criteria analysis methods, simple additive weighting method, final suitability map was prepared. this map prepared with four classes from very low to very high suitability. according to the produced map, suitable areas for construction landfill in malayer region were identified.
