Evaluating the environmental effects of waste burial in Saravan forests using the ANP network analysis model and choosing the appropriate place for waste burial

Today, burying waste is the most common method in many countries due to its lower cost and the existence of a wider spectrum of waste. In the location of the waste burial site, . For this purpose, several multi-criteria decision making methods are used in prioritizing suitable places. In the research, 10 important factors were used to locate the waste disposal site, which are: land use, slope of the area, altitude of the area, geology of the area, distance from roads, distance from rivers, distance from springs, distance from wells, distance from villages. and distance from faults. ANP model was used to prepare the final zoning map. In the first stage, the criteria were prepared and converted into GIS format. Then it was converted to raster format and fuzzification was done. According to the results obtained, the weight of land use criteria, the slope of the area, the height of the area, the geology of the area, the distance from roads, the distance from rivers, the distance from springs, the distance from wells, the distance from villages and the distance from faults for the study area is 0.167. 0.087, 0.036, 0.028, 0.138, 0.064, 0.068, 0.047, 0.120, 0.243 were obtained. Therefore, the criterion of the distance from the faults has the highest weight and the geological criterion has the least influence in locating waste burial areas according to experts. The obtained map was classified in 5 different classes. By examining the overlapping criteria map, it was observed that suitable areas for landfilling are located near rivers and springs and residential and rural areas. By examining the final zoning map, it has been observed that the most suitable areas for landfilling are located in the westernmost part of the study area, with a focus on Agha Seyed Sharif road.
