Analysis of sustainable urban development in Tehran metropolis from the geomorphologic hazards view (Case Study: District One of Tehran Municipality)

One of the fundamental factors in urban planning is the issue of hazards performance evaluation, prediction and control. Our country is located in one of the riskiest areas of the planet in terms of natural hazards and its diversity. Today, natural hazard extend their threats more to the cities and harsh human environments and make their development more vulnerable. This is very evident in a dense metropolis of Tehran, especially in the mountainous region of the district 1.
This research seeks to approach the issue of sustainable urban development in the district 1 of Tehran metropolis with natural hazard approach especially geomorphological hazards. in the present study, at first using library studies, we attempted to evaluate the concept of sustainable urban development and natural hazards and in the next step, field studies were conducted for a comprehensive understanding of the region and with the help of network analysis method, research variables were analyzed and zoned in accordance with the research objectives and ultimately, the assessment of sustainable urban development was defined and explained.
Findings: The research has been designed around two main sections. The issue of zoning of natural hazards, particularly a range of issues was analyzed and in the next step, the sustainable urban development was assessed in the context of natural hazards.
As the study results from hazard zonation and assessment indicate, the region is at a high risk level of 73.11%. The issues such as the weight of urban construction and the natural hazards (poor housing planning), the problems of urban worn out buildings, natural hazards, non-standard gradients and their damage, and ultimately, the slippery landslide of residential areas all indicate that it has to be more careful in the management of land usages and turn up to replace residential usages with low-risk usages such as green space.
