An Environmental Investigation into Khorramabad's Landfill and Optimal Site Selection of Landfill using Weighted Linear Combination (WLC)

The determination ofmunicipal waste landfillis a major issue in the process of urban planning due tothehuge impact it has on the economy, ecology and environment of any region.In the process of determining municipal waste landfill, attempt is madeto consider sites with minimum risks for the environment and human health as well.This study aimedto have an environmentalevaluation and determination of municipal waste landfillin KhorramabadusingGeographic Information System (GIS) andWeighted 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 activitiesare very high in the desired site. Therefore, paying special attention to the environmental impacts ofthe current landfill is of greatsignificance.Then, themap for the site selectionof 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 themap for the site selectionof 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 bestsuitable area, respectively.
