Atualmente, o desenho urbano tem sido realizado dentro de um âmbito restrito do conhecimento. Este não tem considerado aspectos de drenagem da água que trazem grandes transtornos e custos para a sociedade e o ambiente. O desenvolvimento urbano brasileiro tem produzido um aumento significativo na freqüência de inundações, na produção de sedimentos e na deterioração da qualidade da água. Tal situação é decorrente, na maioria dos casos, da ocupação intensiva do solo urbano. Assim, essa abordagem demonstra, inicialmente, uma visão sobre o desenho urbano e suas interfaces; particularmente as relacionadas com a geografia, o ambiente natural e o construído. Na seqüência, pretendendo atingir o enfoque interdisciplinar, aponta vínculos entre o desenho urbano e a hidrologia através de uma análise ambiental de bairros dos municípios de Porto Alegre e Lindolfo Collor, de modo a identificar relações com a utilização de uma variável - a superfície impermeável, procurando descrever o comportamento ambiental de bacias hidrográficas urbanizadas bem como mostrar a necessidade da reserva de área para armazenar água no início do crescimento urbano. Finalizando, apresenta os principais parâmetros ou características de desenho que deverão garantir a sustentabilidade urbana e hidrológica. Apesar de prematuro, pode-se afirmar que existem indícios para que a dissertação venha suprir algumas deficiências existentes no planejamento urbano-ambientalatualmente adotado.

O presente trabalho tem como objetivo entender a atuação do Estado, através da legislação de uso e ocupação do solo, no processo dinâmico de estruturação do meio urbano. Partiu-se da hipótese de que a legislação de uso e ocupação do solo não é instrumento eficaz para contra restar a dinâmica de crescimento da cidade. A formulação dessa hipótese tem como pressuposto que a dinâmica da cidade é determinada pela forma como se dá a reprodução do capital social e, mais especificamente, a reprodução do capital imobiliário. Para testar a hipótese, o desenvolvimento do trabalho compreendeu: a) estudos teóricos; b) uma análise da evolução da legislação de uso e ocupação do solo; c) um estudo de caso. a) os estudos teóricos realizados visaram entender a estruturação do espaço intra urbano de forma a se conhecer a dinâmica do sistema através da apropriação de um uso do solo por outro e de modificações na densidade de ocupação dos terrenos.

The Escritório Saturnino de Brito (Saturnino de Brito Office), created in 1920 under the sanitaristic guidance of the engineer Saturnino de Brito, has a vast record of works throughout the whole national territory, even after the death of its founder, in 1929 at which point his son, and also engineer, Saturnino de Brito Filho, assumed the head of the company , with a compromise to continue his father s work and assure his administrative, technical and urbanistic principles up until the early 1980s, when that institution came to an end. The scarcity of theorical studies about this Office, alongside the importance of the contributions it made in countless cities, oriented the focus of this study on its performance in Natal, where it remained from 1935 to 1969, designing, executing and managing sanitationist works and the services associated with them and going through several political, economical, social, cultural and urbanistic contexts periodicized in this work into three moments. Thus, it is intended to analyze how the Saturnino de Brito Office behaved and adapted itself to the conjunctural changes that unfolded into each of these moments, and more specifically, to observe the forms of intervention adopted the principles, the instruments and the scope aiming to verify the transition of the sanitaristic set of urbanistic ideas into the urban planning as a development strategy on a local level

This work broaches the participation of the Jewish community in the urban expansion of Recife, Brazil, during the Dutch period (1630-1654). With the arrival of the Dutch, the village of Olinda, former capital of Pernambuco, was destroyed and Recife received the juridical statute of city (stad), becoming the capital of Dutch Brazil or New Holland. It became the main West Indians Company s entrepot in South Atlantic, serving as naval base, port of call for ships, and point of export of the sugar production of Pernambuco, and import of European goods and African slaves. In order to such administrative, military and economic functions be carried out, the sand isthmus where Recife used to stay, and the fluvial island of Antônio Vaz, received improvements of many sort. The Dutch hydraulic technology was put in practice, with a posture of opposition between civilization and nature. Among military works and production of urban equipments, the rivers shores were land-filled, canals were built, bridges were lifted, and hundreds of buildings were erected. The civil Dutch population of Recife engaged in the process of production of physical space, which brought a sense of collective action towards the formation of the urban, or burgher, community. From the physical to the social space, there was an effort towards Dutch cultural standards in the urban environment. The Zur Israel Jewish community, formed by private civilians, it is, nonemployees of the WIC, engaged in those processes. It produced physical space through the land-filling and improvement of non healthy areas, and was also responsible for the construction of a significant section of the town s buildings and some of urban equipments, such as stores, markets and slave-warehouses, making more dynamic their economical activities. But their social traffic was due to the adaptation of their behavior to the standards of Dutch sociability. Thus, the community body made itself part of the social body. Disposing of internal selfregulation, it produced spaces with their cultural references cemetery, synagogue, texts enjoying benefits of the government. Zur Israel inscribed itself in the universal history of the Jews as the first community of Americas, and had a fundamental part on the emancipation of Jews within Western society

This paper presents the public square as a subsystem of the city for the potential integration of elements 'natural' and built environment. But sometimes the suitability of projects and the social processes involved are not compatible and favorable to their real functions in urban space. The city of Natal, with a population of 803,739 inhabitants has 253 public parks not uniformly distributed in the urban area, but mostly in central areas and their absence in some peripheral neighborhoods. In this sense, the objective of this paper is to analyze the quality and spatiality of the city's public squares within the urban socio-environmental problems. For this, use of simple random sampling to define the sample and the proportional allocation of districts, totaling 168 squares to be raised. We prepared a form to collect data on the field that includes aspects of leisure, infrastructure and environment. For each square sampled was calculated Square Quality Index (PQI), then calculating the average per IQP neighborhood. The rates found were crossed with census data and Municipal Public Administration by neighborhood, using multivariate analysis. We generated maps, charts and tables, considered appropriate to each question format, focused comparison. The public square appears as an indicator of environmental challenges present in intra-urban spaces of the city. Their spatial distribution is not consistent demand population, both by disposition and by how much. In terms of quality are characterized by different levels of inadequacy and degradation aspects of leisure, environmental and infrastructure, often causing disfigurement, abandonment and improper occupation in such spaces. Multivariate analysis point to a central concentration and their problems in certain administrative units, not only as regards the public squares, but also to aspects of education, income, and other violence, perpetuating the problem. The various levels of inadequacy and degradation of public squares have been more blatant in the poorest neighborhoods of the city, pointing to a structural pattern associated with the intrinsic characteristics of the neighborhood and the socioeconomic profile of the local population. These are problems of social and environmental dimensions, threaded in and influenced the political, economic and broader social process of transformation of the city and the urban. Based on an uneven process in which space necessarily reflect the contradictions inherent in the active forces and interests. Thus evidencing the importance of managing the necessary public effectively engaged with the problems that are present there, in order to equate them, without being prioritized certain areas of the city at the expense of others
