In recent decades, uncontrolled growth of population and urban development have caused various social, economic and environmental conflicts, such as production of municipal solid waste that has followed its inappropriate disposal. So that, how disposal, site selection and correct management of landfill solid waste is one of the urban environmental problems, nowadays. Therefore, finding the appropriate place for this process is one of the first and main objectives of urban development plans to achieve sustainable development. Central part of Kouhdasht city, with production of 110 tons of waste daily, is facing with environmental, social and health problems in this field, due to lack of recycling equipments and its improper disposal place. The aim of this study is appropriate site selection of municipal solid waste disposal in the Kouhdasht city using analysis of human, environmental, hydrological, geological and geomorphologic parameters through AHP model and GIS technique. AHP model is one of the most efficient techniques that designed for multiple criteria decision making. This technique is provides the possibility of formulating complex problems as hierarchy. The results show that we can classify zones of the waste disposal of the Kouhdasht city into five classes. In the meantime, zones and most suitable and suitable, with area of 316.193 and 673.219 Km2 respectively, have highest priority for solid waste disposal and with 24.9 percent of total area in the Kouhdasht city are in the first priority of waste disposal projects. The results of this research would be beneficial in systemic management of urban environment and also in plans of municipal solid waste optimum disposal in study area.
