Site Selection of Koohdasht Municipal Solid Waste Landfill using ANP-WLC Integrated Model

The problem of population growth, changing people''''''''s eating habits, as well as the problem of waste disposal of and management have increased the volume of waste generated in residential centers. Today, how to dispose of, landfill site selection, and properly management of waste landfill, along with the lack of suitable land for this purpose, has become one of the environmental urban problems. Therefore, finding a suitable place for this purpose is one of the important goals of urban development projects to achieve sustainable development. Due to the lack of waste recycling equipment in Koohdasht town, the aim of this study was to find a suitable place for disposal of municipal waste with reference to the environmental considerations and sustainable development. For this purpose, a combined model of network analysis process (ANP) and linear weight combination (WLC) was used in ArcGIS 10.2 software considering 9 parameters: distance from the drainage network (river, waterway), fault, residential areas (city and village), communication lines, wells and springs, as well as geological layers, land use, height, and slope percentage. The results showed that the study area was divided into five classes in terms of fitness. In other words, 19% of the area under study was identified as suitable for municipal waste landfill. The zoning map also shows that fertile lands are designated as unsuitable areas, reflecting the accuracy of the model with terrestrial realities.
