Abstract :

Waste disposal site selection is a critical issue in the urban planning process because of its enormous impact on the economy, ecology, and the environmental health of the region. Waste disposal site selection process aims to locate the areas that will minimize hazards to the environment and public health. The purpose of this study was to determine suitable waste disposal site selection by using the geographical information system and the analytic hierarchy process (AHP) in the study area. In this study first, with using related equations was calculated adequate area to burial chghabale solid waste for 20 years then by using of many data layers such as lithology, land use, soil, road, groundwater and … by using GIS and AHP model was attempted to choice the best location for burial waste of chghabale. According to the results obtained from the map for the site selection of landfill, 15.36%, 20.34%, 27.56%, 29.08% and 7.62% of the site area are located in the very unsuitable, unsuitable, moderate, suitable and the best suitable area, respectively.
