This solution would improve what is left of the existing open green spaces within the city and create new ones that could support a greater biodiversity. It would also provide huge health, social, and ecological benefits that would primarily benefit wildlife and especially citizens. Green infrastructure would also benefit the economic growth of the city because it attracts huge investments and financial support in order to make the urban environment more sustainable. The specific objectives to improve green infrastructure include: a green, high-quality transportation network between small- to large-scale social and traffic nodes, multifunctional spaces, stimulating people to connect more with nature in order to benefit more from it, involving individuals and local communities to take better care of their environment, empowering communities, use of renewable energy sources and better rainwater management. These are just some of the aspects that would lead Tehran to a sustainably developing city.''

	Tehran is a mountainside city with an altitude of 900 to 1700 meters above the sea level located on the southern slopes of Alborz mountains. From east to west, the view is dominated by the Alborz mountains, with rivers that are full in springtime and dry in summertime, flowing to satiate underground water tables hidden in the very thick layers of sedimentary rocks (gravel, sand and clay) from the Quaternary. Multiple aqueducts bring the water to surface that, in turn, flows through irrigation canals and brooks along all streets and avenues of Tehran. Lower parts, between 900 to 1200 m, have a fertile soil and gentle slope that permit a productive agricultural activity. In these plains, there are many sources of surface or underground water tables, supplied by aqueducts, floodways and branched out rivers.

	In the south of Tehran, the desert begins. Dry and very hot weather in summer and sometimes very cold in winter, make this region seem hostile. The contrast between mountain and desert, and even between north and south of the City, prevents weather crises from taking shape in any part of the year. When heavy snow obstructs mountain roads, plains in the rim of the desert have often a mild sunny weather.		In the south of Tehran, the desert begins.

	Tehran region has a dry climate. The annual rate of rainfall is only 229mm at the downtown, 400mm in northern neighborhoods and less than 150mm in arable lands of south. Heavy rainfalls in Alborz mountains, mainly as snow, provide a fairly reliable source of water supply for Tehran’s residents and the City’s development. This water flows through a number of rivers and flood canals toward the desert in the south and is swallowed up by the thick layers of alluvium.		Tehran region has a dry climate.

	*''Main River Valleys in the City		'''* ''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. This case study concentrates on Darband river valley.		Seven main river valleys pass through the city, including Darakeh, Velenjak, Darband, Golab Dareh, Jamshidyeh, Darabad, and Kan.

This case study concentrates on Darband river valley.
	This river (“the Furious River” with 295/000/000 m3 of water per year) flows down from North mountains, passes beyond Hezardarreh hills, east of Tehran, and irrigates the great arable plain of Varamin.''

	*''Overall Character and Current Conditions		'''* ''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		'''* ''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		'''* ''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.
