Abstract :
Proper location of landfill sites is a critical concern in urban waste management, because it directly affects the environment, public health, and resource management. This research is titled "Urban Landfill Site (Case Study: Bandar Abbas City) It intends to address this challenge with a comprehensive case study of Bandar Abbas city. This research focuses on two main questions: What are the most important indicators and effective criteria in determining the optimal place for urban waste disposal in Bandar Abbas? To answer this question, Fuller's weighting method was used to rank different criteria. The analysis showed that proximity to the river (with a score of 0.0713) had the highest importance, followed by distance from water wells (0.0681) and proximity to aquifers (0.0633). This evaluation examines the causes and factors affecting the choice of suitable landfill sites in Bandar Abbas city. Based on spatial analysis, which areas are more suitable for landfill in Bandar Abbas city? Using Geographical Information System (GIS) software and according to the weights obtained from the previous analysis, the evaluation of the suitable landfill sites in Bandar Abbas was done. The results indicate that approximately 16.17% of the city area, which is mainly concentrated in the central belt of the city, is considered very suitable for landfilling. In addition, 25.98% of the city's area falls under the category of suitable landfill sites. This research provides valuable insights in the field of identification and spatial analysis of landfill sites in Bandar Abbas, which can guide urban planners and waste management officials in making informed decisions. The findings emphasize the importance of considering environmental factors, such as proximity to water sources, in establishing landfill sites to ensure sustainable municipal waste management in the region.
