Feasibility of landfill establishment in Khomeynishahr city of Isfahan using GIS, MCE and Boolean logic

Abstract

Land filling is the most common disposal method in most parts of the world and landfill site has always been the final destination in solid waste management hierarchy. Thus, the selection of landfill site is always an essential part in the management of solid waste. Selecting an appropriate site for landfill minimizes any unwarranted ecological and socio-economic effects. Hence, landfill site selection requires a detailed analysis of the area that must be able to meet the local authority requirement and criteria. The present study presents a feasibility assessment of landfill establishment for Khomeynishahr city in Isfahan, applying a multi criteria evaluation (MCE) method using GIS technique. Information layers related to topography, soil, water table, sensitive habitats, land use and geology maps were prepared and superposed using Boolean logic in GIS environment. Essential analysis and regulation, criteria and site selection assessment showed that because of many limitations khomeynishahr city doesn't have adequate conditions for landfill site establishment. Khomeynishahr city has a dense population and limited area and is not suitable for landfill establishment. In this case consideration of adjacent cities and finding a common landfill site between two or more cities could be a viable solution of solving this problem.
