Landscape and/or urban context of your case
- Biogeography, cultural features, overall character, history and dynamics
- Main River Valleys in the City
Seven main river valleys pass through the city, including Darakeh, Velenjak, Darband, Golab Dareh, Jamshidyeh, Darabad, and Kan. All of these come from Alborz Mountains of Tehran, and after passing through urban areas reach lower plains in the south, where they meet agricultural lands. My case study concentrates on Darband river valley, which passes alongside my neighborhood.
- Overall Character and Current Conditions
By carefully looking at the map, Darband river valley and its path is recognized due to its especial natural form. But if we want to follow it in the city, it is not so easy. Some parts of it have been buried under buildings or streets. Other parts of it have been converted to "U" channels and covered by impervious materials such as stone. In terms of flora, except some scattered trees, which are planted alongside the wall of the river valley, there is not major planting adjacent to that. Actually the deep channels surrounding the bed of the river valley has taken the opportunity to plant trees, shrubs, or other kinds of vegetation. Right after the end of the river's walls, there are streets and buildings. This lack of attention to Darband river valley causes people to undermine it and throw their wastes in this river-channel, and this in turn causes major environmental pollution in the site.
- Flora
Tehran is rich in terms of the diversity of flora. While some of them are native to Iran, few, if any, of them are endemic to Tehran. Up to now, 13 endemic species of Tehran are known: Eritrichium mertonii (Family Boraginaceae), Buffonia hebecalyx (Family Caryophyllaceae), Stellaria scaturiginella (Family Caryophyllaceae), Centaurea carduiformis subsp. iranica (Family Compositae), Tanacetum polycephalum subsp. junesarens (Family Compositae), Taraxacum darbandense (Family Compositae), Convolvulus gracilininus (Family Ipomoea), Astragalus latianicus (Family Papaveraceae), Astragalus pseudobrunsianus (Family Papaveraceae), Hedysarum elbursense (Family Papaveraceae), Hedysarum hyrcanum var. hyrcanum (Family Papaveraceae), Vicia sojakii (Family Papaveraceae), Galium tehranicum (Family Rubiaceae). All of these species are herbaceous, which aren’t currently used in parks and landscapes. Predominant species of Tehran which are widely planted in parks, streets, and open spaces as well as alongside the river valleys are Platanus orientals, Morus nigra, Ulmus minor ‘umbraculifera’, Fraxinus excelsior, Quercus spp of broadleaved trees; Pinus eldarica and Cupressus arizonica of conifers; Lignustrum vulgare, Viburnum opulus, Nerium oleander, Berberis thunbergii of shrubs; and Common grass and Hedera helix of cover plants.
- Connectivity to the Wider Green/Gray Structures
Darband river valley in its journey from Alborz Mountains toward plains through the middle of the city links many important services and facilities from urban to local scales. One of the most important structures is North Mountains itself, which during the week and weekends attract thousands of people to hike, mount, and spend leisure time. On the other hand, the river valley passes through main, high traffic roads and highways, which everyday millions of citizens use to go their work. All of these green/Gray structures stress the importance of this historical river valley and affect the river both negatively and positively. Before such an incredible development of the city, when all of the city with its borders was limited to current city center, most parts of these river valleys were far away from the city and its effects. At that time, mostly private gardens and orchards formed their banks.

What are the overall objectives of your design? What are the specific objectives for enhancing green infrastrucutre?
Please give a short written argumentation (not more than 150 words). It is ok if you have different or even contradicting objectives within your group. Just make it explicit at the beginning of your process
Analytical drawings
Please add four analytical sketches/drawings (or montages/schemes) of your case. Every group member needs to contribute at least one drawing.

Projective drawings
Please add four projective sketches/drawings (or montages/schemes), of course with an emphasis on green infrastructure aspects. Every group member needs to contribute at least one drawing representing his/her individual ideas.

Design Synthesis
Please analyse the individual approaches presented so far and evaluate their strengths and weaknesses (you may use the SWOTanalysis model). Try to create a synthesis and represent it with a plan and some sketches. You can still use drawings/sketches.

Summary of the collaborative process
Please reflect on your collaborative design process. Which potentials have you encountered? What was most difficult? What does collaborative design mean for you? (approx 150 words).
Image Gallery
You may add a series of images/photos in addition to the sketches/drawings
