Solid wastes have been an inseparable part of human life and the production of the wastes, in different levels of quality and quantity, is considered to be one of the major challenging issues of the environment in this era. Air and water pollution and soil which is the result of the lack of correct management and lack of choosing appropriate landfills to bury the wastes, have all created some problems for the environment. change the sentence. In order to decrease the negative outcomes of the wastes, it is essential to use the right tools and technology. One of the main parts of management in the urban solid wastes is finding an appropriate place in order to dispose the wastes. This study was done to locate the appropriate landfills in the city of Givi through using GIS technology. In this study the following parameters, criteria and rules for hygienic disposal on the basis of different standards such as Environment Conservation Organization, Ministry of Interior and worldwide experiences were identified, evaluated and selected: geology, infrastructure, seismic city of the areas, slope, land use, distance from rural and urban centers, soil plan of the area, hydrographic network plan, underground waters and the prevailing wind direction. Then, appropriate places in this area were identified according to national and international rules and standards and also by applying limiting factors through GIS. To integrate the layers and obtain the appropriate results, Bolin Logic was used. Through field visits, three locations for comparison and evaluation through hierarchical analysis process were selected and ultimately by doing closer studies on the selected locations and exerting appropriate weights on each of the locations, the final location will be selected.
