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. پرونده مقاله

Natural hazards have always changed the environment and threatened human life. In this regard, geological hazards including earthquake, subsidence, etc. are the most destructive natural factors that our country, Iran, is affected by them. That is why planning and preparation to deal with these catastrophes is essential. Aerial communication networks have an important role in the relief operation because of the rapid access after an earthquake. The purpose of this study, is locating an appropriate site of air rescuing after a casualty. Hierarchical analysis method was used for weighting after determining the effective indicators in locating; including the area of open space of the site, access to dense and vulnerable texture, service user and main arteries. After preparing the final map, zones of avoidance were announced. The evaluation method similarity to ideal option in the software environment of the spatial information system was used to select the final site. This study is an applied research because of its aim and it has been carried out using descriptive - analytical method. According to obtained results, three squares called Sanat, Saheb-a Zaman and Farhang were selected as suitable sites. Sanat square was identified as an appropriate site because of having the highest score according to defined criteria پرونده مقاله
