For this reason, site selection in solid waste sanitary landfill is a great importance in terms of ensuring a 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 utilizing ArcGIS software.
