Having subsumed flatlands to the east and west and seventy villages on its adjacent mountain slopes, now Tehran varies 800 meters in elevation from south to north. The rapid growth of the city has resulted in different pollution and environmental changes. As the awareness of environmental quality has noticeably increased throughout the last decades, the need to regenerate degraded urban areas, preserve and restore natural resources, and improve water quality beside space qualities is highly necessitated. In order to alleviate the environmental problems, landscape architecture should take the main role in the urban extension planning and design. In this study, Tehran riverfronts are analyzed in order to achieve a high quality environment. The seven river-valleys that pass through Tehran have been reviewed as a cohesive urban planning for the future extensions. To achieve the detailed concepts of riverfront landscape planning design, Kan River was chosen as the case study in Tehran. Different sections of the Kan River are analyzed with regard to ecological and landscape aspects and thereby some general landscape strategies were achieved. These strategies are concluded by the concept of Rehabilitation of Tehran river-valleys. The study of Kan River is aimed to provide insight into the main principles of its rehabilitation. Although the Kan River is used as a case study, regarding its similarity to the other rivers in Tehran, the rehabilitation principles could be used for other rivers in Tehran as well.

New concepts of urban green development emerged in that time. Some of these ideas where extremely creative and vanguard from there era and still some of them are the main theoretical basics of urban green planning in the modern world. This paper focuses on Isfahan's greenway planning ideas and discusses how the city transformed to a sustainable city in Safavid period. The discussion is based on the combination of the organic and planned forms of greenway design, which was unique by that time and made the garden city of Isfahan. The Maddies 1 , which are the branches of water derived from the river and flowed inside the urban context, are studied as the bases of organic greenway and the Charbagh 2 and Naghshe-Jahan Square are investigated as the planned green developments.

This rapid growth has led to an unplanned urban development which has caused major environmental problems and a severe lack of human contact with nature. Owing to this fact, it is crucial to devise a comprehensive urban plan with a new landscape ecology approach to bring the nature back to human realm for the future development of the city. In this study municipal district 22 has been considered as a case study for the future extension of Tehran boundaries. This municipal district has a great capability towards urban development. In order to achieve suitable urban planning in this zone, an interconnected system of green spaces is planned which provides ecological network for the city according to landscape ecology principles. Planning this green network has been considered at three different scales with regard to a hierarchical approach towards urban landscape: Regional, Municipal and Local scales. At the Regional scale the main natural ecological resources are taken into account. At the Municipal scale quarter parks and green thoroughfares are considered as the main components of the ecological network regarding to the potential opportunities of the urban network. And at the Local scale extensions of the proposed ecological network penetrate into the heart of the urban fabric and especially residential spaces. The study of municipal district 22 is aimed to provide an insight into the main principles of Tehran urban extension with a landscape ecology approach. Although this zone is considered as a case study, regarding to its similarity to the other zones beside Tehran's boundaries, the principles could be generalized as a model to other zones as well.
