Floods caused by extreme hydrological events and their consequences are one of the major challenges faced by local government authorities about urban planning. In this context, we studied the urban cross channel sections behaviour located in the Jatobá stream catchment, in the city of Belo Horizonte, Brazil. Different precipitation scenarios were used as input parameters for the hydraulic simulation. For this purpose, the accumulated rainfall was disaggregated and a frequency analysis was performed to compute different duration times (from 10 to 120 minutes) and return periods (from 2 to 100 years). Then, hydrological and hydraulic simulations were carried out using HEC-HMS and HEC-RAS models, respectively. The results showed that the average time until the channel overflows was 58 minutes and the average duration time for the overflow was 28 minutes. The channel overflowed in 77.14% of the simulated scenarios. The simulations were carried out for different rainfall return periods and time duration to characterize extreme events for this catchment, aiding the decision- making process and assisting in the development of strategies to improve the drainage system.

Este trabalho discute a vulnerabilidade do sistema de drenagem urbana da cidade do Recife sob o aspecto urbanístico e climático (precipitações intensas e oscilações de maré). Realizou-se uma pesquisa bibliográfica, apresentando um diagnóstico expedito sobre as peculiaridades da drenagem urbana da cidade, discutindo as intervenções estruturais realizadas no sistema e as medidas implementadas para o enfrentamento das mudanças climáticas. Verificou-se que as ações e medidas que propiciem uma melhor adaptação para a adequação do sistema de drenagem na região, diante da influência das alterações climáticas, ainda são muito tímidas. De uma maneira geral, conclui-se pela necessária gestão integrada do saneamento, a efetiva aplicação das medidas não estruturais, e a utilização combinada de técnicas compensatórias e estruturais que vise à sustentabilidade do sistema, considerando também, os efeitos das alterações climáticas.    A B S T R A C T This paper discusses the vulnerability of urban drainage system of the city of Recife considering the urban and climate aspect (intense rainfall and tide oscillations). It presents an expeditious diagnosis on the urban drainage peculiarities of the city, discussing the structural interventions carried out in the system and the measures implemented for coping with climate change, considering the aspect of the urban drainage. It was verified that the actions and measures that allow a better adaptation to the adequacy of the drainage system in the region, given the influence of climate change, are still very timid. It is concluded, in general, in favor of the necessary integrated management of sanitation, the effective implementation of non-structural measures, and the combined use of compensatory and structural techniques aiming at the sustainability of the system, considering the effects of climate change as well.  Keywords: Urban planning; climate change; urban drainage.

Several indicators are developed to support the decision-making processes in public policy for urban planning. Some of them seek to measure the quality of urban life. For example, the city of Belo Horizonte developed and uses an index called Quality of Urban Life Index, which identifies inequalities within the city, and therefore, those areas that need more investment. This index is calculated by measuring the availability of various kinds of services (e.g. education, infrastructure) and their accessibility (based on travel time and mobility data). For that, data from several government sources must be collected and used, which can delay updates of index values. In this chapter, the authors describe how data from Location-Based Social Networks (LBSN) can be used to calculate urban indicators, and hence, how they could be used as an alternative data source for estimating quality of urban life with faster results to support urban planning policies.

[222 pp, RRP: £18.75, ISBN: 978-1-910781-22-7]The idea of discovering or creating a form of uniqueness to differentiate a place from others is clearly attractive. In this regard, and in line with Ashworth (2009), three urban planning instruments are widely used throughout the world as a means of boosting a city’s image: (i) personality association - where places associate themselves with a named individual from history, literature, the arts, politics, entertainment, sport or even mythology; (ii) the visual qualities of buildings and urban design, which include flagship building, signature urban design and even signature districts and (iii) event hallmarking - where places organize events, usually cultural (e.g., European Capital of Culture, henceforth referred to as ECoC) or sporting (e.g., the Olympic Games), in order to obtain worldwide recognition.

Состояние проблемы. Проблематика городской среды заявила о себе в 1960-е годы как протест против модернистских методов урбанизма и других видов проектирования. Средовое движение не случайно тогда именовали «антипрофессиональным» - оно было направлено против устоявшихся и недейственных методов работы с городом - от исследования до управления. За прошедшие десятилетия в рамках самого средового движения и его идейных наследников наработано немало методов и приемов работы, однако они до сих не подвергались анализу как пребывающая в исторической динамике целостная совокупность инструментария, альтернативного традиционному градостроительству. Результаты. Рассмотрены особенности и проблемы анализа методологического «арсенала» средового движения и урбанистики. Методы работы с городской средой впервые структурированы по типам знания. Показана близость методов исследовательского и проектного подходов в отношении городской среды. Выводы. В ближайшее время можно ожидать появления новых синтетических знаний и частных методологий, связанных как с обострением средовой проблематики, с расширением круга средовых акторов, так и с процессом профессионализации урбанистики. Statement of the problem. The urban environment paradigm emerged in the 1960s as a protest against the modernist methods of urbanism and other types of design. It was no coincidence that the environmental movement was back then called "anti-professional" as it was directed against the established and ineffective methods of working with the city, i. e., from research to management. Over the past decades, within the framework of the environmental movement and its ideological heirs, a lot of methods and have been developed. However, they have not yet been analyzed as an integral set of tools in the historical dynamics which is an alternative to traditional urban planning. Results. The features and problems of the analysis of the methodological “arsenal” of environmental movement and urban studies are considered. The methods of working with the urban environment are first structured according to the types of knowledge. The proximity of research and design approaches in the case when the urban environment is dealt with is shown. Conclusions. In the nearest future, we can expect new synthetic knowledge and particular methodologies related to both the exacerbation of environmental problems to emerge as well as the expansion of the circle of environmental actors and the process of professionalization of urbanstics.

Since the late 20th century major, European cities have exhibited large projects driven by neoliberal urban planning policies whose aim is to enhance their position on the global market. By locating these projects in central city areas, they also heighten and reinforce their privileged situation within the city as a whole, thus contributing to deepening the centre–periphery rift. The starting point for this study is the significance and scope of large projects in metropolitan cities’ urban planning agendas since the final decade of the 20th century. The aim of this article is to demonstrate the correlation between the various opposing conservative and progressive urban policies, and the projects put forward, for the city of Madrid. A study of documentary sources and the strategies deployed by public and private agents are interpreted in the light of a process during which the city has had a succession of alternating governments defending opposing urban development models. This analysis allows us to conclude that the predominant large-scale projects proposed under conservative policies have contributed to deepening the centre–periphery rift appreciated in the city.

The present research offers an exploration into the biophilic approach and the role of its agents in urban planning in questions of building a green, resilient urban environment. Biophilia, the innate need of humans to connect with nature, coined by Edgar O. Wilson in 1984, is a concept that has been used in urban governance through institutions, agents’ behaviours, activities and systems to make the environment nature-inclusive. Therefore, it leads to green, resilient environments and to making cities more sustainable. Due to an increasing population, space within and around cities keeps on being urbanised, replacing natural land cover with concrete surfaces. These changes to land use influence and stress the environment, its components, and consequently impact the overall resilience of the space. To understand the interactions and address the adverse impacts these changes might have, it is necessary to identify and define the environment’s components: the institutions, systems, and agents. This paper exemplifies the biophilic approach through a case study in the city of Birmingham, United Kingdom and its biophilic agents. Using the categorisation of agents, the data obtained through in-situ interviews with local professionals provided details on the agent fabric and their dynamics with the other two environments’ components within the climate resilience framework. The qualitative analysis demonstrates the ways biophilic agents act upon and interact within the environment in the realm of urban planning and influence building a climate-resilient city. Their activities range from small-scale community projects for improving their neighbourhood to public administration programs focusing on regenerating and regreening the city. From individuals advocating for and educating on biophilic approach, to private organisations challenging the business-as-usual regulations, it appeared that in Birmingham the biophilic approach has found its representatives in every agent category. Overall, the activities they perform in the environment define their role in building resilience. Nonetheless, the role of biophilic agents appears to be one of the major challengers to the urban design’s status quo and the business-as-usual of urban governance. Researching the environment, focused on agents and their behaviour and activities based on nature as inspiration in addressing climate change on a city level, is an opposite approach to searching and addressing the negative impacts of human activity on the environment. This focus can provide visibility of the local human activities that enhance resilience, while these are becoming a valuable input to city governance and planning, with the potential of scaling it up to other cities and on to regional, national, and global levels.

Like in many other provinces, during the Habsburg period, the main point of orientation for Galicia was Vienna. This also applies to architecture and urban development. Galicia’s technical elite applied the theoretical and practical experience it gathered in Vienna to the towns and cities of this northeastern Crown land. Ignacy Drexler, born in 1878 in the Austro-Hungarian Lemberg, was a representative of a new generation of engineers and architects who did not necessarily have to spend time in the imperial capital to earn their spurs. Increasingly, besides the more or less obligatory stay in Vienna, other European countries became points of reference. Drexler did not live to see the realization of important aspects of his comprehensive plan for the city, but his ideas and the data he compiled were indispensable for the future development of his hometown. They shape urban planning in Lviv to this day.

Rock Size

A system comprising a UASB reactor, shallow polishing ponds and shallow coarse filters, treating actual wastewater from the city of Belo Horizonte, Brazil, has been evaluated. The main focus of the research was to compare grain sizes and hydraulic loading rates in the coarse filters. Two filters operating in parallel were investigated, with the following grain sizes: Filter 1: 3 to 10 cm; Filter 2: 8 to 20 cm. Two hydraulic loading rates were tested: 0.5 and 1.0 m3/m3.d. The filter with the lower rock size had a better performance than the filter with the larger rock size in the removal of SS and, as a consequence, BOD and COD. A better performance was obtained with the hydraulic loading rate of 0.5 m3/m3.d, as compared to the rate of 1.0 m3/m3.d. The effluent quality during the period with the lower loading rate was very good for discharge into water bodies or for agricultural reuse (median effluent concentrations from Filter 1: BOD: 20 mg/L; COD: 106 mg/L; SS: 28 mg/L; E. coli: 528 MPN/100 mL).

В статье представлен обзор тематики выпускных квалификационных работ по градостроительству, представленных на Международный смотр-конкурс дипломных проектов архитектурных вузов, проводимый Межрегиональной общественной организацией содействия архитектурному образованию (МООСАО) в 2018 и 2019 годах. Проведенный анализ позволил сформулировать современные направления развития градостроительного знания по смысловым категориям проектов: технологические проекты; стратегические проекты различных уровней; проекты развития урбанизированных территорий; проекты уникальных тематик (освоение космоса, Арктики, концепции города будущего, проекты на территориях зарубежных государств). The article provides an overview of the topics of diploma works on urban planning submitted to the International Review Competition of architectural projects of university graduates held by the Interregional Public Organization for the Promotion of Architectural Education in 2018 and 2019. The analysis made it possible to formulate a generalization of topics into semantic categories: technological projects (technologies for urban planning, environmental-friendly planning, participatory design); strategic projects of various levels (the development of agglomerations and resettlement systems, strategies for the development of cities and historical centers, the modernization of transport systems, as well as projects to form the “nuclei” of economic growth); urban development projects (reconstruction of existing buildings, renovation of communal and warehouse areas of the city, development of disturbed territories, public space projects under the federal program “Formation of a comfortable urban environment”); projects of unique topics (space exploration, the Arctic, the concept of the city of the future, projects in foreign countries).
