Application of GIS Models in Site selection of waste disposal in Urban Area

Landfill siting should take into account a wide range of territorial and legal factors in order to reduce negative impacts on the environment. The suitability of selected site for disposal center affects the amount of generated energy and the cost of disposal generation. Suitable sites should be determined on the basis of technical, economical and socio-environmental issues. GIS along with appropriate models and spatial analysis method can be used to define the suitability of different locations for the construction of disposal centers. This research focused on determining suitable locations for construction of a suitable disposal centers. Our study area is Saqqez city in Kurdistan province in North West of Iran. At the first, important parameters in hazardous material disposal center sitting for studied area were identified. Then, the maps of studied area were prepared and integrated. Boolean, index overlay, and fuzzy logic models were used for integrating of maps. The suitable locations for the waste material disposal center were selected using each model. Finally, in index overlay and fuzzy logic model, 0.12% and 0.17% of the study area was selected as suitable, respectively. In both of the methods, the majority of suitable area was located in south east of city, where waste demand is more than other places. KeywordsWaste disposal; Site selection; GIS; Saqqez city.
