Artigo recebido em 09/11/2015 e aceito em 24/12/2015 R E S U M O O espaço urbano é objeto de constantes modificações e produção do espaço, sendo a vida na cidade definida pelas relações econômicas, sociais e culturais, que se apresentam altamente dinâmicas e mutáveis com o passar das décadas. Torna-se importante o planejamento do espaço urbano, visando a prevenção de impactos negativos, em parte pela rápida expansão desordenada das cidades e adensamento urbano. O objetivo desta pesquisa é analisar a distribuição da rede de drenagem superficial do bairro de Santo Amaro ao longo dos séculos e verificar espacialmente, a partir dos dados históricos do Censo IBGE, algumas informações relativas à drenagem e esgotamento. Para tal foram utilizados mapas históricos da cidade de Recife, fotografias aéreas dos anos de 1974, 1981 Time-space evolution of surface drainage and waterproofing process in Santo Amaro, Recife-PE A B S T R A C T Urban space is subject to constant changes and production space, with city life defined by economic, social and cultural, that have highly dynamic and changing over the decades. It is important to the Urban Planning, with a view to preventing negative impacts, in part by the rapid sprawl of cities and urban density. The objective of this research is to analyze the distribution network of surface drainage of the Santo Amaro neighborhood for centuries and check spatially, from historical IBGE Census data, some information relating to drainage and sewage. To do this they used historical maps of the city of Recife, aerial photographs of the years 1974, 1981 and 1997 and 2007 Recife city ortofotocarta and 2014. All these were georeferenced and recorded. They were also used satellite images Landsat TM sensor 5 which were calculated the albedo of the surface and the EVI. They were tabulated and spatially the IBGE Census data. It was observed a decrease in vegetated areas inside the lots and increased waterproofing in much of the neighborhood, which significantly influences the runoff. Keywords: land use change, flooding, remote sensing. IntroduçãoO espaço urbano é objeto de constantes modificações e reprodução, sendo a vida na cidade definida pelas relações econômicas, sociais e culturais, que se apresentam altamente dinâmicas e mutáveis com o passar das décadas. Torna-se importante o planejamento do espaço urbano, visando à prevenção de impactos negativos, em parte pela rápida expansão desordenada das cidades e adensamento urbano (Berman, 1982). Na tentativa de disponibilizar novas áreas urbanas na área central do município, diversas
A B S T R A C TThe rapid development of the environment and urban planning are increasingly demanding of management, celerity, and readiness in solving difficulties. Considering the development in the environment, companies invest in technologies and information modelling; when the State administration adopts these, it can contribute to the improvement of the operation of several aspects, reflecting the social and environmental quality of the regions of interest. Taking into account The rapid dissemination of communication and the advancement of technology, this work aimed to analyze the concepts that approach the considerations of Building Information Modelling-BIM and City Information Modeling-CIM for cities, presenting their functionalities and benefits. The methodological procedures that conditioned the organization of the data presented here were fundamentally a bibliographical survey to select the literature that would compose the theoretical basis of this research. The conception of BIM and its benefits to the academic community, the revolutionary arrival of CIM and the contribution of these forms of modelling to the formation of sustainable cities are analyzed and discussed. It is concluded that the modelling of BIM and CIM and its vast and integrated database can provide several benefits to the design, engineering, architecture and related areas, assisting in the management of projects, observing the area available for construction and the natural resources of the region. It is possible to create cities in the sustainable model, potentializing energy generation, water and soil use, population transition/seasonality and reducing unnecessary costs.

Urbanization is one of the most powerful anthropogenic causes of Earth change. The report by the Intergovernmental Panel on Climate Change claims that human influence on the warming of the soil, ocean and atmosphere is unequivocal. People who are socially, economically, culturally, politically, institutionally or otherwise marginalized are especially vulnerable to climate change and also to adaptation and mitigation responses. Climate injustice refers to the fact that groups in a greater situation of vulnerability present challenges that accumulate as a result of less political power and great social inequality and, therefore, are disproportionately harmed by the impacts of climate change. Thus, this article seeks to address, from indices such as the NDBI, NDVI and census data from the IBGE Census, for the year 2010 and data from the analysis of Climate Risks and Vulnerabilities in Recife, the climate (in)justice in the city of Recife. For this purpose, 3 images from the TM sensor and one from the OLI sensor aboard the Landsat satellites were used. Results show that NDBI values above 0.21 were extended to various areas of the city of Recife over the years, while the NDVI showed a decrease in vegetation cover, indicating greater soil sealing and construction of buildings. These results, in accordance with the mapping of vulnerabilities to climate change, corroborate that a public policy focused on reducing climate injustices is essential, especially when it is concluded that the areas with the greatest social vulnerability are those with the greatest climate vulnerability.
