Landfill location is one of the most important aspects of municipal solid waste management. Geomorphology is of great importance in optimal location due to its nature, which relates to the origin and development of landforms and their formation processes. Hashtgerd region with an area of 398 km2 is located south of Savojbolagh city of Alborz province. Due to its location on the alluvial cones of permanent rivers (Kordan) and high permeability of lands, the presense of surface water and groundwater layers sometimes at a low depth (less than 50 meters), population areas (urban and rural) and abundant agricultural lands, optimal landfill location in this area in a way that does not damage the surrounding environment is of great importance and necessity.The purpose of this research is optimal location of landfill in Hashtgerd area using AHP method and considering the geomorphologic parameters. The research method is analytical-comparative method. In this research, topographic maps of 1:25000 and geological maps of 1: 100000, as well as data related to groundwater in the study area were used and ArcGIS software was also used for analysis. In the present article, based on four main criteria, namely geology, hydrology, topology and land use, five areas were obtained for locating the landfill. The result of the research shows that the areas are perfectly suitable for landfill in the eastern and southern parts of the area around Mohammad Abad Afshar village and the areas in the western parts of the region are entirely inappropriate for landfill because of the location of population and agricultural areas and the groundwater low depth (7 to 32 m) in this part of the region.

Selecting a site for solid waste landfill is an important procedure in managing municipal solid waste and landfill sites should be selected with great precision and through a scientific process. Therefore, it is possible to select an appropriate site for solid waste landfill in accordance with environmental criteria using geographic information system. The present article is descriptive-analytic. Secondary research and field study were simultaneously used for data collection. It seeks to locate an optimal site for solid waste landfill in Faruj city. In this study, we first investigated factors and principles of locating municipal solid waste landfill according to valid resources. Then, maps of influential factors on locating municipal landfill were prepared and valuated based on information layers and spatial analyzer tool, using geographic information system. According to geological indexes, distance from the river, distance from residential area, landfill is located in an inappropriate zone. Ultimately, the maps were integrated and combined. Analyzing the final map of Faruj solid waste landfill, we concluded that locating principles and standards were disregarded and the present landfill site is in an inappropriate zone.

The present study describes and compares the spatial method and spatial statistics by a combination of different methods of science in different fields such as multiple criteria analysis of GIS. The ultimate goal of this method is to assess the appropriateness of the area in question in order to determine the optimal location for landfill. In this context, the first step is the formation of a hierarchical structure of multiple criteria. Next, it is using the spatial analysis process to establish evaluation criteria, these based on the laws of Greece and the European Union, and also on the basis of practical and feasible international guidelines. The relative importance of the assessment criteria is determined based on the hierarchical structure and, using simple weighing model, suitable sites for landfill in the study area are determined. as a result, suitable locations are ranked from 0 to 10, which is from the lowest to the best, respectively. The last stage is the process of spatial clusters, which are designed to represent the most appropriate area. The initial ranking permits the selection of suitable places for burial from among existing places. The application and implementation of the proposed method on the Lemnos island in the north of the Aegean Sea showed that 9.3% of the studied area was suitable for burials above the 9th level.
