Physical planning and design of urban spaces with emphasis on natural hazards (Case study: Zabol city)

Today, in order to reduce the vulnerability of urban physical spaces to natural hazards and the need to make the right decisions and implement appropriate operations, as well as due to the advancement of human knowledge and technology, To provide a clear picture of the consequences of hazards, it is necessary to assess the physical design of urban spaces in proportion to natural hazards. Therefore, the purpose of this study is to plan and physically design the urban spaces of Zabol with emphasis on natural hazards.

The research method is analytical and based on library, documentary and field studies. SPSS and GIS software and ANP and WASPAS models were used to analyze the information. The statistical population in the present study consists of two parts. The first part is related to the residents of Zabol, where the Cochran's formula (385 people) was determined as the sample size. In the second part, based on purposive sampling, 20 local experts and knowledgeable people were selected as the sample size in this section.

T-test results showed that all the items, the average obtained is lower than average number 3, indicating non-compliance with the physical spaces of Zabol design is based on natural hazards. The multiple linear regression test results indicate that the design of physical spaces of Zabol and natural hazards, the 99/0 high reliability, there is no significant relationship. The results of ANP model in GIS software environment showed that in most layers, regions two and three have the highest value. Finally, the results of WASPAS model showed that Area two, with a weight of 3.923, has the highest level of physical design based on natural hazards.

In the areas of Zabul city, the physical condition was assessed as unfavorable based on natural hazards, and these areas have a different condition due to the influence of natural hazards in physical planning and design.
