Abstract
BACKGROUND AND OBJECTIVES: Urban river valleys are so important with regard to their benefits and functions, including air temperate, microclimate creating, landscape, fresh water supplement. Urban development over considering environmental issues, population density, constructions, solid waste or effluent discharging, especially in quantitative and qualitative river boundaries and land taking of their beds, are significant reasons to decline cities functions and ecosystems degradation. So, natural ecosystems should be restored and a thorough strategic planning is necessary for their conservations.    
METHODS: With regards to managerial aspects involving ecological, spatial, economic, socio-cultural, and managerial- executive dimensions integrated management model has been recommended for Farahzad River Valley in Tehran city as a case study via Urban River Survey and Geographic Information System. Finally, effective and efficient strategically management plan was suggested by implementing SWOT, QSPM and Analytical Hierarchy Process.
RESULTS: Amongst 12 identified strategies regulation settings, “correlation between green space and the surrounding park”, and “preventing the increase of residential” and “the expansion of recreation” are prioritized as most significant strategies, scores have been calculated 5.616, 5.589, and 5.375 on QSPM matrix or 0.256, 0.192, and 0.133 by AHP method, respectively.
CONCLUSION: in overall, systemically, multi dimensional and holistic decision of river valleys environmental management is a magnificent example that provides essential tools to urban planners. Environmental and ecological approaches of the model are counted as a main key of succession to sustainable development achievement and its advantage to other past studies.
