Sit Selection of Waste Disposal Site Based on Hydrological and Geo-Climatic Management (Case Study: Kian City)

The production of waste has caused environmental crises that pose serious threats to the life of creatures on Earth. This study aimed to evaluate the strategy and location of waste disposal site in Kiyan watershed with an emphasis on EIA through survey-analytical method. Based on the locating process, a suitable landfill site of 10 hectares was selected in the village of Karke-oliya. As basalt-andesite rocks have high permeability and are resistant to erosion, the proposed area has high environmental capacity for waste disposal. Data from the Meteorological Organization show the prevailing wind direction within the study area is northwest. The western wind dominates, and since the villages of the study area are northwest and west of the landfill area, the effects of the landfill's unpleasant odor will be far off. In addition, since the area is enclosed in terms of topography, which can be seen in the transverse and longitudinal profiles of the region, the effect of the displacement of lightweight waste by the wind has been neutralized. It is important to note that the suggested burial ground is far from natural drainage, which makes the area suitable for landfill for hydro geological watershed purposes. The results of the environmental impact assessment also showed that the project has a positive impact of about 45%. Therefore, the proposed site is well-suited to environmental standards.
