To date, the vast majority of river sedimentology study has relied on two main categories of observation: direct observation of shallow trenches, cut faces and cores or geophysical survey on dry and shallow regions of braid bars. In this study, a sub-bottom profiler was used to investigate the stratigraphy of the lower course of the Tocantins River in the Amazon region, between the city of Tucuruì and the village of Nazaré dos Patos. The interest in this specific region lies on the possible variation of the fluvial regime due to the installation of the dam of the Tucuruì hydroelectric plant and the perspective that such river would become navigable as soon as the canal lock will be completed. Collected data show a detailed variety and complexity of architectural elements, as well as internal structure of sandy macroforms. Furthermore, the results allowed the identification of three main environments linked to channel sedimentation processes: by-pass, transition and deposition environments, whose distribution is linked to channel dynamics and bedrock topography. The application of the study is manifold, once it provides not only an insight into sedimentary structure of alluvial forms and sedimentation history, but also elements demanded to plan eventual engineering works for river navigability.

By definition, a monument has extraordinary features that mark landscape and human minds alike. Without any doubt, the Medieval and Early Modern World of Europe was marked by ecclesiastical monuments, from great cathedrals and abbeys to simple chapels and altars at crossroads. A very interesting case study offers Braşov/ Kronstadt/Brassó, in the south-eastern corner of Transylvania, where historical sources attest several ecclesiastic monuments, in and around the city. Late medieval and early modern documents and chronicles reveal not only interesting data on the monasteries, churches and chapels of Braşov/Kronstadt/Brassó, but also on the way in which citizens and outsiders imagined those monuments in their mental topography of the city. The inhabitants of Braşov/ Kronstadt/Brassó and foreign visitors saw the monasteries, churches and chapels of the city, kept them in mind and referred to them in their (written) accounts, when they wanted to locate certain facts or events. The present paper aims in offering an overview of the late medieval and early modern sources regarding the ecclesiastical monuments of Braşov/Kronstadt/Brassó, as well as an insight into the imagined topography of a Transylvanian city.

Cities are engines of socio-economic development. This article examines and provides insight into the extent of localisation of the UN’s Sustainable Development Goals (SDGs) using the City of Bulawayo (CoB), in Zimbabwe, as the case study. The key question posited is ‘Does Bulawayo demonstrate potential for sustainable development?’. Bulawayo is a strange case study as in the period of the Millennium Development Goals Zimbabwe had a massive increase in death rates from 2000 to 2010 due to the HIV pandemic, political chaos and economic disintegration of that period. Coming out of that period there was little to help cities like Bulawayo grasp the opportunity for an SDG-based development focus. However, after the paper creates a multi-criteria framework from a Systematic Literature Review on the localisation of the SDG agenda, the application to Bulawayo now generates hope. The city is emerging from the collapse of the city’s public transport and water distribution systems, once the envy of and benchmark for many local authorities in the country, and has detailed SDG plans for the future. Bulawayo now serves as a planning model for localisation of sustainable development goals.

The Olympics have a greater, more profound and more pervasive impact on the urban fabric of their host cities than any other sporting or cultural event.  This paper is concerned with issues of memory and remembering in Olympic host cities.  After a contextual introduction, it employs a case study of the Queen Elizabeth Olympic Park (QEOP), the main event space for the London 2012 Summer Games, to supply insight into how to read the urban traces of Olympic memory.  Three key themes are identified when interpreting the memories associated with the Park and its built structures, namely: treatment of the area’s displaced past, memorializing the Games, and with memory legacy.  The ensuing discussion section then adopts a historiographic slant, stressing the importance of narrative and offering wider conclusions about Olympic memory and the city.

At the moment there are few comprehensive texts or instruments that allow architects, designers, historians, planners or even students the ability to understand the complex layers of a city’s urban fabric. As a result, this paper was prepared in order to be uploaded to a digital tool that allows for such exploration of the built environment.   The transformation of the city of Rome is documented in a number of sources and as a result makes it the ideal city for study of architectural and urban evolution.  As a case study in digital documentation this paper examines the medieval façade porticoes of Rome at three scales: urban, architectural, and detail.  The identification and mapping of these structures, are shown together allowing one to examine them in relation to historic and present day city maps.  In addition, their location is analyzed in relation to ancient Roman streets and historic processional routes, to observe the connection amongst their location and that of major thoroughfares of antiquity, the Middle Ages, and the Renaissance.  At the architectural scale, the detailed documentation in plan and elevation reveal four distinct variations that existed in the use of the residential façade portico.  At the scale of architectural detail, an inventory of reused architectural elements or spolia that make up the residential porticoes reveal the reuse of ancient Roman column shafts, bases and capitals as well as the medieval masons’ preference for the use of the Ionic capital in particular.  This paper prepares a methodology for digital deployment of traditional scholarship focused on architecture and the built environment.

Quinta das Laranjeiras, owned by the merchant and military José Gonçalves da Silva, is part of the landscape of the outskirts of the city of São Luís do Maranhão from the time of its construction, in 1789, until the present day. Located at the end of the old Caminho Grande, now Oswaldo Cruz street, the Quinta has a private chapel and an imposing portal decorated with lioz stones, which reproduces the coat of arms of the Portuguese merchant. Functioning as landmarks of the boundaries of this site, these architectural elements remained during the 19th and 20th centuries as a reference for the urban evolution of São Luís, even after the various stages of the uncharacterization of the Quinta and its surroundings. In this sense, this article intends to discuss the concept of historical urban landscape attributing to Quinta das Laranjeiras the necessary patrimonial potential for a case study that understands the derivations of this category. Using UNESCO and IPHAN definitions of cultural landscape as parameters, we will analyze the formation of a stratification of meanings that have been accumulated through the historical and economic processes, in addition to punctuating the effects of the toppling of Quinta das Laranjeiras.

This chapter outlines the journey that the city of Londonderry (Derry), Northern Ireland, undertook when converting a traditional walled city to a technology-enhanced wireless city. The chapter presents an overview of the three project strands, namely wireless city (civic aspect), wireless walls (tourism aspect), and wireless campus (educational aspect), along with the contribution made by each partner organization. A detailed case study of the educational element is presented, employing a dual qualitative/ quantitative research approach. The case study focuses on the experience of one academic member of staff in using the wireless initiative via Tablet PC and SMART classroom. Quantitative analysis to gain insight into usability of wireless networking services and wireless technologies is presented from both a staff and student viewpoint and finally conclusions are drawn on the overall project experience. The project successfully, completed in December 2006, has received a number of awards for its innovative approach.

This research investigates the mechanism of urban village redevelopment in south China. Through a revised typology of place entrepreneurs based on the growth machine thesis and a case study of Liede village in central Guangzhou, it illustrates how land-based interests embedded in an imbalanced power relationship can (de-)activate urban village redevelopment. The study reveals that while urban villagers, as represented by the village collective, have entrenched interests in the redevelopment process, the city government – as monopolistic land manager and place entrepreneur – plays the deciding role in forging and halting a growth machine geared towards urban village redevelopment. Although developers are also part of the process, the (de-)activation of redevelopment growth machine/coalition in Guangzhou has largely been dominated by the city government. With a comparative view on the original growth machine model, it is hoped that this study would furnish both theoretical and practical thoughts for future research.

In the 1950s, the city of Casablanca underwent a surge in demographic growth. Having become a strategic port during the French protectorate, it quickly had to accommodate more than 140,000 new arrivals from the countryside. The most extensive urban development project in the city was Carrières Centrales, introduced as a case study in the CIAM IX by the GAMMA team. Michel Écochard, Candilis and Woods reinterpreted the traditional Moroccan house in a compact horizontal fabric as well as in singular buildings. This became the typology not only for a house, but for the whole city. A revisit to Carrières Centrales 65 years after its construction provides an understanding of the metamorphosis that the urban fabric has undergone over time. The critical analysis in this research aims to uncover the main architectural and social parameters that have influenced its transformation. To achieve this goal, fieldwork was carried out during a research trip in October 2018. The work involved contacting local professors, accessing the archives of the University of Casablanca, interviewing the residents, and redrawing and graphing all the architectural elements that had changed since their construction. The urban fabric of Carrières Centrales was found to have evolved in a way that supports the following hypothesis: if an urban model imported into a developing country does not adapt to the changes in the life of its residents, it is considered a failure.

The development of the industrial world, especially the automotive industry in Indonesia, has experienced quite a significant development, this is indicated by the number of requests which each year increases, in line with the needs and demands of the community for adequate transportation facilities. Indonesian people, especially in the city of Tembilahan, are now more fond of automatic motorbikes than the duck type. The type of duck motorbike is a type of small motorcycle that is built on a frame which mostly consists of a large diameter pipe. There are several factors that researchers see that occur in the field, especially in purchasing products, namely the lifestyle in the environment and the existing popularity. The results of the study: Lifestyle has no effect on purchasing decisions with. Popularity influences purchasing decisions Lifestyle and popularity influence purchasing decisions as a whole. And the path analysis obtained an indirect effect of lifestyle on brand experience through purchasing decisions, namely -, 125%, while the indirect effect of popularity on brand experience through purchasing decisions is 7.14%.
