Abstract: 

ONE OF THE MOST IMPORTANT ENVIRONMENTAL PROBLEMS IN MOST PARTS OF THE COUNTRY, ESPECIALLY IN GILAN PROVINCE, IS THE UNHYGIENIC DISPOSAL OF GARBAGE. THIS HAS CAUSED SOIL AND GROUNDWATER POLLUTION. RASHT IS ONE OF THE MOST IMPORTANT CITIES IN THE NORTH OF IRAN, WHICH COVERS AN AREA OF 136KM2 WITH ABOUT 500TON/DAY OF WASTE GENERATION. THEREFORE, IT IS VERY IMPORTANT TO DETERMINE A LONG-TERM SUITABLE PLAN FOR WASTE DISPOSAL IN THIS AREA. CURRENTLY, THE WASTES CARRY IN SARAVAN FOREST WITHOUT TECHNICAL CONSIDERATION. THEREFORE, IN THIS PAPER RASHT LANDFILL WITHIN SARAVAN FOREST HAS BEEN CHECKED AND ANALYZED BY GIS TO DETERMINE ITS EXPANSION AREA DURING THE PAST YEARS. IN THIS REGARD, THE LANDFILL AREAS IN 2006, 2007 AND 2009 WERE CALCULATED USING SATELLITE IMAGES AND FIELD DATA TO CHECK THE TREND OF AREA EXPANSION DURING THESE YEARS TO ESTIMATE THE FUTURE AREA CONDITION. THE ENVIRONMENTAL IMPACTS ANALYSES SHOW THAT THE LANDFILL SITE SELECTION IS UNSUITABLE. ALSO, THE LANDFILL LATEX FLOWS TOWARD THE SIYAHROUD RIVER DUE TO THE TOPOGRAPHY, LACK OF COLLECTION SYSTEM IN THE LANDFILL AND THE AREAL SLOPE. THE RESULTS ALSO SHOW THAT ABOUT 16 HECTARES OF FOREST LANDS DESTROYED IN THIS AREA DURING THE PAST YEARS TILL 2009 AND ABOUT 25 HECTARES IS REQUIRED FOR LANDFILL SITE IN THE YEAR OF 1400. THIS MEANS THAT 9 MORE HECTARES OF THE SARAVAN FOREST WILL BE DESTROYED IN ADDITION TO RIVER AND GROUNDWATER POLLUTION DAMAGES. FINALLY, SOME SUGGESTIONS ARE GIVEN TO REDUCE THE NEGATIVE IMPACTS.
