Sustainable Stream Corridors Towards a Vision of Green Infrastructure Case Study: Tehrans Evin-Darakeh Stream Corridor

The fast pace of development of tehran (a capital city with a population of 12 million and grandiose ideas) over the last 30 years is the major cause of the deterioration of the natural environment and watershed. stream corridors in the northern part of the city are the major areas for most of the wildlife diversity in tehran and are easily affected by human intervention. the two major elements of the stream corridors are soil and water, if either of these is affected by human activities the ecosystem will become unhealthy and its natural balance will be unsettled. therefore special consideration to environmental capacities is essential. this study was conceived on the basis of a phenomenological approach; an extensive literature review on the subject and the case study were also conducted. the research attempts to consider the evin-darakeh stream corridor as a green infrastructure by describing the benefits of green infrastructures. in order to reach this goal, planning principles for this stream corridor and the related strategies are explained.
