“…Accordingly, the synergy between urban streams and rivers and urban form is complex (Penn, 2001;Solomon, 2011;Phong, 2015;Mosler, 2021) whereby each influences the other and both are influenced by the settlement's social, economic, and cultural conditions (Silva et al, 2006;Abshirini and Koch, 2016;Mosler, 2021). There are nevertheless clear longitudinal, lateral, and vertical socio-spatial connections between streams and the town plan (Kondolf and Pinto, 2017).…”

Fluvial reclamation to facilitate urban development leads to culverting, hence, a loss of urban streams. Using the palimpsest analogy, we examine how the Amman Stream in Amman (Jordan) historically provided regulatory and socio-cultural ecosystem services through its socio-spatial (longitudinal, lateral, and vertical) connections. We then explore the impact of the stream's culverting, partially in 1967 then completely in 1997, on these connections and, consequently, on ecosystem services. To overcome data paucity, our methodology relied on constructing spatial data by georeferencing and digitizing aerial photos and satellite images (from 1953, 1975, 1992, and 2000) using ArcGIS. We augmented our data with archival research (historic and contemporary documents and maps), an online survey among Amman's residents, and in situ observations and photography. The results reveal striking contrasts between the historic and contemporary configuration of urban form vis-à-vis the Amman Stream. Throughout its early urban history during the Classical and early Islamic periods, the urban form elements reflected reverence and prudence toward the Amman Stream as manifested in the investment in water infrastructure and the alignment of thoroughfares, civic monuments, and bridges that collectively capitalized on the land relief (the strath) and established strong connections with the Amman Stream, maximizing, in the process, its regulatory and socio-cultural services. In contrast, the contemporary urban form replaced the stream with car-oriented roads, hence, eradicated its regulatory services and replaced its socio-spatial connections with urban socio-economic and cultural fissures. Accordingly, we propose to daylight (de-culvert) the Amman Stream to restore its regulatory and socio-cultural services and its socio-spatial connections. We substantiate the feasibility of daylighting through: (1) morphological analysis that reveals that roads cover most of the stream; (2) the survey's findings that indicate public support; and (3) the cascading benefits for the larger watershed in a water insecure region.

“…Furthermore, urban integration has resulted in the continued compression and fragmentation of ecological space (Abshirini and Koch, 2016;Hesse and Siedentop, 2018). Changes in spatial use due to an increase in population causes spatial integration and urban agglomeration, resulting in spatial interactions and patterns of distribution of goods and services.…”

Economic growth and urban agglomeration have triggered an increase in the size and mobility of the Metropolitan Mamminasata urban population. This study aims to analyse spatial interactions working as a determinant of connectivity of the transportation system and the growth of suburban areas toward smart and sustainable cities in the Mamminasata Metropolitan urban system and the effects that spatial expansion, spatial integration, urban agglomeration, spatial use, and the transportation system have on population mobility. The research method used is a sequential explanatory design that combines quantitative and qualitative research methods. The results show that the coefficients of determination are as follows: spatial expansion to population mobility – 4.90%, spatial integration to population mobility – 2.99%, spatial interaction to population mobility – 4.87%, urban agglomeration to population mobility – 2.09%, space use to population mobility – 2.64%, and transportation system to population mobility – 5.15%. The results of this study will assist in the formulation of development policies, management of the urban transportation system, and allocation of space utilisation going forward.

“…Waterways are not only important for urban geographical environments but because they influence and confine their surrounding urban morphology they also perform a vital role in the shaping of societies and their economic growth (Abshirini & Koch, 2016;; Xie & Gu, 2015). Urban morphology can be considered an important approach to urban design and studies in the creation of urban form.…”

Reviving the Urban Water-Edge: History and Heritage Morphology in the Envisaging of Chittagong City

Ancient settlements were dependent on the availability of water for sustainable living, ritual values, and economic purposes. Today, many Tropical Asian cities provide examples of urban settlements within water landscapes, yet these cities struggle with water issues, and face challenges in creating a contextual morphological identity. This paper explores urban waterfront heritage through a case study of Chittagong, Bangladesh. The city is experiencing rapid unplanned urbanisation, insensitive land use and the demolition of historical buildings along waterways, which in turn has created a contextual crisis in the built environment and social living. To explore the relationship of built heritage with the water-edge, this paper examines historical architectural styles using urban morphological codes. Results show that the historical orientations, accessibility, and functions of heritage buildings are explicitly and sensitively connected with the water-edge. The paper argues that physical and spatial components of urban structure and water landscape, incorporating the lessons of urban history, could become a tool to preserve urban heritage. However, to enhance the image of the city in a sustainable manner along water-edges, it is crucial to use the potentiality of water landscape with the heritage-based morphologies in current urban design and development practices.
