The Need for Environmental Assessment and Field Surveys in Landfill Location Studies (Case Study: Yazd City)

The need for a comprehensive management of sustainable environmental development is more than ever due to the growth of population and more waste production. In order to achieve the goals of sustainable development, environmental assessment before, during and after each project is needed. The purpose of the environmental impact assessment is to ensure that managers and experts meet the goals set in a project in accordance with government and environmental regulations. The first step towards achieving this goal will be exploring the study area. In this research, the Leopold matrix was used for environmental assessment of landfill location in Yazd. Environmental assessment was done on the problems resulting from landfill on the environment and living organisms of the area in the environmental assessment area by visiting the field of the current landfill site of Yazd. The total score of the results of the Leopold Environmental Assessment Matrix related to the current landfill site was -214. Therefore, it is possible to carry out management solutions to improve the status of the current landfill. By performing location studies using the hierarchical analysis method, zone one was designated as a suitable landfill site. The soil permeability gradient curve of the selected region was prepared and the soil type of this region was clayey silt. Which will be suitable for landfill.
