A Study on Evaluation of Site Selection in Sanitary Landfill with Regard to Urban Growth

Sanitary landfill is a widely used waste disposal method worldwide due to its safe and economic. The most important issue in this storage method is the process of selecting the landfill. This process is one of the critical issues in the urban planning process due to its enormous impact on the region's economy, ecology and environmental health. At the same time, it is also a great importance for public health. Urban growth is a phenomenon that is difficult to stop or limit in line with economic dynamics and demographic changes. For this reason, site selection in solid waste sanitary landfill is a great importance in terms of ensuring sustainable urban future. The site selection in sanitary landfill is made conventionally taking into account environmental, social and economic criteria. In this study, the waste disposal facility, which was built according to the mentioned criteria and still in operation, was evaluated in the context of urban growth. In this context, Landsat TM 1989 satellite image for the determination of urban boundaries of the central settlement area of Sanliurfa before the irrigation of the GAP project, and Sentinel-2 satellite image enrichment to determine the urban development boundaries after irrigation was mapped by Screen digitizing. Its spatial evaluation and mapping were performed by means of ArcGIS software.
