Assessment of land suitability for urban landfill site selection with an emphasis on natural factors (Case study:Joghatay City )

Iran produces over 48,000 tons of waste per day (three times the global standard), which imposes huge costs on municipal spending every day. In terms of economic factors, land use, and access. In this research, Geodatabase database was created in ARC.Map .10.5 software using topographic maps, geology, statistics and climatic and demographic and hydrological information and satellite images. 11 digital layers were made of factors affecting landfills in geomorphological, geological, hydro-climatic, environmental and access subdivisions. Then, appropriate and appropriate weights were given by surveying the experts and urban experts, and the criteria of the hierarchical analysis method (AHP) were proposed. The best areas for burying waste. Demonstrated population data analysis from 1985 to 1995, the population of Jaghtai will reach 1,730 in 1415, given the population growth rate and production will be 43,800 tons of waste, so a 2-hectare area is needed to bury the waste. The research results show that 43 square kilometers of the central part of Jaghtai is suitable for the creation of a landfill site; which is one of the options. It is also recommended to use the site of the southwestern marginal site of Jaghtai city suitable for temporary landfill, construction of waste separation unit or compost production unit due to excellent access.
