locating landfill in urban areas by Analysis Network Process(ANP)

It is essential to ensure that environmental regulations are observed and that sustainable development goals are taken into account as well to prevent environmental pollution. The location of waste landfill sites and the achievement of sustainable development goals must be supervised. The study area is Gonabad city in Khorasan Razavi province. It has three urban points (Gonabad-Kakhk-Bidokht) Which is burial of urban waste near two cities of Gonabad and Kakhk. The purpose of this research is to provide optimal and desirable locations for urban waste dumping in Gonabad city. The first stage of municipal waste management is their proper location. For this research, the most important indicators used for locating were: distance from water resources, vegetation, soil texture, elevation, gradient, distance from communication paths, distance from faults, and the distance from demographic points. Layers and data were weighed on the basis of ANP and using the GIS, suitable landfill locations for urban areas were identified. Then, the ANP model final map after the formation of the network and the calculation of weights were obtained by successive sum of standardized layers and the resulting map was classified in four zones (perfectly suitable, appropriate, relatively suitable and inappropriate). The method of research is based on the descriptive-analytical nature and based on the purpose of applied research. For collecting information, two methods of documentary and field-survey have been used.
