The first dimension that visibly manifests itself in the process of development and transformation of cities is the physical dimension. From a morphological perspective, this dimension systematically examines and analyzes the gradual evolution of the form, shape, layout, structure, physical composition, and functions of the artificial fabric of cities, as well as the processes responsible for the transformation of these fabrics over time. This perspective implicitly establishes a link between the spatial and material elements of the city and its constitutive social and economic forces. A lack of balance and equilibrium in development within this framework can lead to isolation, disengagement from the environment and society, alienation among urban residents, and, ultimately, segregation. This is why, in recent years, with the rapid pace of urban development, increased construction activities, and extensive changes in the physical and morphological structure of Iran's major cities, Tehran has been grappling with phenomena such as spatial and social segregation and its accompanying challenges. This trend is manifested in adjacent urban fabrics with completely contrasting structures, creating a cityscape that reflects socio-economic, and even managerial, disparities between neighborhoods. The innovation of this research lies in addressing and quantitatively assessing the duality and contradictions that represent segregation and disparity among urban residents within an area that, although administratively part of the same urban district, exhibits vastly different characteristics in various dimensions of urban life.
In the detailed plan of District 2, it is stated that this district, in comparison to other districts of Tehran, enjoys a relatively better status regarding socio-economic indicators (such as household size, household income, and the number of households per residential unit). However, in certain parts of the district, such as Farahzad and Eslamabad, urban fabrics with informal settlement characteristics have emerged. Therefore, this study, with the aim of examining the interplay between urban morphology and socio-spatial segregation, focuses on the Darya neighborhood in District 2 of Tehran, which exemplifies contrasting urban fabrics. The research methodology is descriptive-explanatory, and data collection methods include
observation, interviews, library studies, and questionnaires. For data analysis, content analysis, space syntax analysis, comparative means analysis, factor analysis, and regression analysis were employed. The findings indicate that, while urban morphological factors (as a subset of the causes of
segregation) have a one-sided influence on segregation, and not vice versa, factors such as social homogeneity, environmental livability and safety, the economic and symbolic attractiveness of the neighborhood, spatial configuration and morphological systems, neighborhood selection due to accessibility, and finally the size of blocks and plots play a significant role in the residential choices of socio-economic classes in Darya neighborhood. These factors can explain 60.3% of the impact on social classes. The majority of the morphological impacts on segregation in this context are primarily due to environmental livability and safety, spatial configuration and morphological systems, neighborhood selection based on accessibility, and block size. Planning, policies, and action plans that consider these factors can contribute to a constructive interaction between urban morphology and socio-spatial segregation.
