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.
