Locational of Zahak municipal landfill, using Geographic Information System (GIS)

Zakhak city with a total area of ۹۴۵ square kilometers is located north of Sistan and Balouchestan province and is located in the geographical position ۸۹۴۴. ۳۰ degrees north and ۷۰۶۷. ۶۱ degrees east. The city's population, according to the ۲۰۰۶ census, is ۷۱,۴۶۲, it generates ۲۵ tons of waste per day. These wastes accumulate behind the hospital in Zahak, where environmental pollution for residents of nearby villages is one of the most important problems due to the misplaced location of the site. The study area is located in the Sistan block in terms of Structural-sedimentary divisions in Iran. NQ stratigraphic unit is the largest stratigraphic zone in Sistan Plain, consisting of alluvial fine-grained sediments in a river whose sedimentation time from the end of the Miocene to the early days of the Holocene continued. These sediments are often the result of erosion lake plain and drainage, shapes today to have gained in the context of all the villages, settlements and activity centers formed and large parts of the East area The study encompasses the study. In this research, it has been attempted to investigate the geomorphology of the area with the overlap of gradient layers, elevation digital, geology, roads, distance from the city, distance from the well, distance from the river and priority drainage system with the help of GIS. Then the banned areas were identified, so that the eastern parts of the city of Zahak are more preferable.
