Rationale: Why is this case interesting?
River valleys are a valuable feature of Tehran in this arid climate. They act as lungs of a city which bring fresh air from mountains. Unfortunately, there is not much attention to this natural feature in Tehran. Actually, in many parts of the city, their beds have been covered by non-permeable materials, and even worse they have been replaced by highways with a lot of natural and social consequences. On the other hand, Tehran is also a metropolitan with huge inner-city travels and a burgeoning interest in walking and biking. However, there are not safe and enjoyable spaces to comfortably walk and bike. I see these river valleys a great opportunity to convert to an ecological pathway. Besides discharging stormwater, they have a remarkable potential to more integrate communities, more tie people to nature, make people healthy, and provide a sustainable delightful transportation network.
Author's perspective
On one of the projects at my previous workplace, I, as a team member, worked on adjacent neighborhoods of a highway. This highway passed through tight neighborhoods with strong relationships. After detailed studies, we found out this highway caused extraordinary disintegration within the communities so that even some children had to pass on the highway to reach their schools. After living near one of these highways which once was a river valley, I have more deeply perceived this disintegration as well as huge noise and air pollution. This has always been my challenge that following this fact that we have a lot of north-south river valleys which have a great potential to convert to a green infrastructure and we need more ways, why we don’t restore these valleys and improve green transportation with the help of them. More dedicating spaces to automobiles means more pollution, more congestion, more illnesses, and more disintegrated communities, while providing delightful environments to walking, biking, and convenient public transportation means more healthy citizens, more environmentally friendly infrastructures, and more sustainable environments and communities, which is what river valleys can give us. Sometimes, I really desire to bike or walk to my destination but in this polluted and automobile-oriented city, I hardly even persuade myself to go out! I believe this metropolitan with burgeoning population and inner-city travels needs a redefinition of their transportation network toward a sustainable future. My intention of studying this case is restoration of river valleys with the approach to green, high quality pathways.
Landscape and/or urban context of your case
- Main River Valleys in the City
Six main river valleys pass through the city, including Darakeh, Velenjak, Darband, Golab Dareh, Jamshidyeh, and Darband. All of these come from North Mountains of Tehran, and go toward lower plain in the south, where they meet agricultural lands
