Locating the waste landfill site of Bam City using multi-criteria decision- making modeling in GIS environment

The location of sanitary landfills is one of the most important environmental issues in cities. If the design of landfills is not appropriate, it will threaten human health. The aim of the current research is to locate waste burial using geographic information system in the city of Bam, this research is applied in terms of its purpose and its method is descriptive-analytical. Based on this, the effective criteria in the location of Bam's landfill were identified, prepared and standardized. Then by digitizing and weighting 8 layers based on the existing standards, including: topography, geology, slope, fault, waterways, communication lines and distance from the city, and importing the mentioned layers into the software environment and forming special burial databases. Waste and implementation of various analytical multi-criteria decision-making models on the existing layers. According to the layers used and the final map obtained, the studied area was classified in the form of four classes: very suitable, suitable, unsuitable and very unsuitable, and it was determined that the most optimal waste burial space is in the southeast of the region, and the least optimal space is in the northwest of the city. There is. The issue of waste management, or beyond that, material cycle management, is one of the main and very important axes of sustainable development today. Therefore, it is necessary to put the necessary infrastructures for the best possible management of urban waste, which has not yet been done and requires proper management and implementation of economic plans.
