The determination of municipal waste landfill is a major issue in the process of urban planning due to the huge impact it has on the economy, ecology and environment of any region. In the process of determining municipal waste landfill, attempt is made to consider sites with minimum risks for the environment and human health as well. This study aimed to have an environmental evaluation and determination of municipal waste landfill in Khorramabad using Geographic Information System (GIS) and Weighted Linear Combination (WLC). For this purpose, the current landfill was first assessed in terms of the environment. The results of the evaluation show that the biochemical and chemical activities are very high in the desired site. Therefore, paying special attention to the environmental impacts of the current landfill is of great significance. Then, the map for the site selection of Khorramabad's landfill was prepared based on investigating and assessing 13 parameters including the distance from city, village, river, groundwater, fault, major and minor roads, airport, historical places, lithology, land use, slope and elevation. According to the results obtained from the map for the site selection of landfill, 10.03%, 21.85%, 28.38%, 25.30% and 14.42% of the site area are located in the very unsuitable, unsuitable, moderate, suitable and the best suitable area, respectively.
