Introduction
Management in general is the art and knowledge of efficient and optimal use of resources to achieve the goal, and waste management or waste management is in fact all the planning and activities in the field of waste and in order to reduce, move, convert, Decontamination or disposal of waste takes place. Waste management system consists of different parts. This system can be compared to a chain that in the absence of a loop, the chain will be broken, so the performance of each waste management will affect other parts. Although the waste problem has been solved in many cities of the country and may have become a source of prosperity for the city,In the metropolis of Ahvaz, due to the lack of a clear strategy and proper investment in recent years, it has not been able to bring prosperity to the city and always a lot of garbage in the people, has caused a huge amount of dissatisfaction of citizens.

Material & Methods
According to the research topic, the research method is descriptive-analytical. In this regard, first, using GIS software, the situation of waste landfill in Ahvaz city has been studied, then the geographical distribution of suitable places for waste landfill in this city has been studied. For analytical work, maps that have been in the form of polygons have been turned into rasters, and maps that have been in the form of point and linear features have been determined using the Euclidean distance to determine their importance in relation to the landfill. In order to determine all the maps, the importance of classification has been applied to them. Finally, using the FAHP method, the weights obtained from this method are multiplied in the obtained layers, and the final map, which includes the current location of the Ahvaz landfill and the proposed locations, is obtained. In the next stage, using the opinions of experts living in Ahvaz, managerial, economic, environmental and social indicators have been studied. In order to analyze the data, statistical and graphical analyzes in GIS and SPSS were used.

The results of the study showed that in terms of location and environment, the ambassador landfill site is in a good condition and the problems of Ahvaz city in relation to waste disposal are due to its proper management . The studies of this study show that in the spatial survey of Safireh landfill, environmental criteria have been relatively observed. Among the landfills around the city of Ahvaz, from 5 very unsuitable to very suitable conditions, Safireh site is in a good condition, which can be said that the location of this site is suitable in terms of environmental characteristics.
