Ahmadi, Vahid, Chi-Ani, Adi Irfan, Farkisch, Hero, and Surat, Mastor. "Morphological Study of Urban Hierarchy in Boshrooyeh City of Iran," in ArchNet-IJAR: International Journal of Architectural Research, vol. 6, issue 3 (2012): 56-71.
City designs in Iran have used the hierarchy principle in all elements of the cities from the components to the whole. The physical cells of tissues in an urban area are clearly related. However, in the development of cities, traces of the network of space communications to the old city centre remain. Instead of composition streets, squares and communication between, the networks contain filled rows with independent buildings. The purpose of this article is to recover the specific relationships between elements of the city and the urban hierarchy with regard to morphological aspects. In this study, urban tissue and typology are used to assess the pattern of urban streets, blocks, squares and islands. The typology of urban tissue based on evaluation of the mentioned patterns is established through field studies, aerial photos and maps of separated lands. We chose the city of Boshrooyeh in eastern Iran as the case study. The historic city core sector has been evaluated in terms of physical characteristics, which provide the morphological typology of the urban tissue. After analysis, data can be investigated in the presence or absence of access hierarchy in different historical periods of the city. The purpose of identifying the morphological typology of the city’s historic fabric is to help us determine the hierarchical order and coherence of the city. The result of this study shows the rapid development of the city, including widening streets, and destruction of the urban form (Main Street and Square). These incidents have led to loss of infrastructure, urban identity, and disorganisation in the urban hierarchy.
