ABSTRACT
Background & objective: The lack of suitable landfill for storage and disposal of solid wastes in different parts of Guilan has been not only led to deforestation and agricultural lands destruction, but also jeopardized public health. The Langroud County as a tourist destination of Guilan province is also affected by solid wastes. Therefore, the present study aims to locate the new appropriate area for municipal sanitary landfill, taking into account environmental standards in Langroud County.
Materials & Methods: In this research, 20 criteria were used in accordance with the standards of the Iranian Environmental Protection Agency, the Alberta State Environmental Authority of Canada, the Minnesota Pollution Control Agency and the British Columbia Environmental Ministry as criteria for locating. TOPSIS method was used in combining the criteria maps in ArcGIS software environment.
Results: After passing TOPSIS and combining the layers obtained in the ArcGIS software environment, the final map of urban landfill location within the study area was classified into five classes (very weak, weak, moderate, good and excellent).
Conclusion: Based on the results, five prestigious areas in the south and southwest of the city with the highest degree of fit and excellent grade were proposed as new areas of urban solid waste disposal for the city of Langroud.

Introduction: One important problem in the rural areas is the issue of locating an appropriate landfill for solid wastes. Rural environmental protection is among the essentials of a rural developmnet. Lack of management in a sanitary landfill is a sign of Lack of planning and Lack of considering the various environmental issues. The present study with the aim of locating a suitable landfill for rural solid wastes was conducted in Mahneshan city. Methods: In this research, to assess an appropriate landfill for rural wastes in mahneshan town, eight important and efficient parameters in locating an appropriate landfill including slope, elevation, distance from the rural points, channels, roads, faults, protected areas, and mines were considered. The identified parameters were compared by incorporating the Analytic Hierarchy Analysis (AHP) method in a pairwise manner and the corresponding weight of each factor, which indicates the effect of that factor, was calculated using the Expert Choice software. Results: by combining the weight layers obtained in the Arc GIS environment, the final location map for considered landfill was prepared and categorized in 5 classes (completely inapproppriate, inapproppriate, intermediate, approppriate and completely approprite). Conclusion: The results showed that in this categorization, the appropriate and completely appropriate zones with 643.9 and 374.5 squre kilometers had the highest preferability for the considered landfill respectively. These zones were prioritized with a 36.9% of the total area of the town, for this matter.
