Abstract:

Like many other cities, Tehran is experiencing the increasing pressure of improper land use and incorrect land management policies which have exacerbated the problems by disregarding the limitations and potential of land and its vulnerability and fragility against possible changes. The implementation of suggested plans and projects will be carried out for north-western of Tehran, such as the establishment of the west urban man made lake as the largest man made lake of Iran, based on the detailed feasibility studies. In the present study, on Environmental Impact Assessment study (EIA) for the largest man made lake in Iran by using environmental modeling and using overlay method in Geographic Information Systems (GIS) with a land use planning approach and regards to the ecological environment and by considering the results of satellite image processing was performed. The area observed is in north-western of Tehran, a region of about 10, 000 ha, which is restricted by the Alborz mountain chain in the north. This study aims at considering major changes on human environments, caused by proposed project execution in the north-western of Tehran by using satellite data. Then, by using environmental modeling and using GIS and overlay method for using environmental impact assessment analysis, decision can be made based on the capacities and environmental balances of the area by applying the results of different analyses in GIS, regarding whether the projects are operational and where is the best location for making the largest man made lake of Iran and how they could be improved. The socio-economic and cultural situation of the District-22 has also been described. The interactive effects of the activities and suggested actions of the implementation of the plan have been specified during the constructional and operational phases. Finally, the strategic and management plans for the location of man made lake and environmental impact assessment of the man made lake in north western part of Tehran are presented by consideringtheoverlay analysis results and proper actions are suggested to reduce the negative effects
