Application of fuzzy logic (fuzzy) and Analytical Hierarchy Process (AHP) in locating landfill for household waste in Marvdasht city with an emphasis on Hydro climatic parameters

Locating suitable sites for household waste landfill (dirty gold) is of important actions in the process of comprehensive management of urban waste. The current location of the landfill in Marvdasht, in addition to its capacity fullness, is located in an unsuitable environment. The effects of its environmental pollution has emerged not only in the current situation but also will better show his negative effects in the near future and Finally, the sustainable development of this city will face with a crisis. The Purpose of this research is the locating of household waste land fill in Marvdasht city and reducing its resulting damages to water and soil resources. In this study, the land physiographic factors, the distance from the legal limit of the city, distance from the road, distance from the man-made features ( village, urban facilities and equipments and mines), distance from the faults in the region and also review the hydroclimatic condition including distance from the surface waters , wind direction, temperature, precipitation in GIS environment have been used. Firstly, the limitations of the study area from the view point of waste land fill, extraction and then the amount of data layers based on fuzzy membership functions and based on their desirability in relation with the target were placed in the standard range of zero and one. Finally, these layers were combined based on the extracted weights through AHP and linear- weight composition and then the suitable areas for landfill of household waste were determined. The findings of the research indicate that the study area was divided into 4 classes, in which the fourth class in the final map was determined as the most suitable place for burying household waste and construction waste recycling technology (dirty gold) Marvdasht city
