This fact is associated, among other reasons, to an expressive land occupation and soil water-sealing and to the occupation of the areas under risk of inundations the meadows and bottoms of valleys. The research below analyzes the different concepts for handling pluvial waters under the scope of reflections relative to the infrastructure works and public actions addressed to prevent inundations. We tried to present the hygienist vision regarding the increase in water conductivity up to the new environmental vision of sustainable rain water handling, highlighting the use of non-structural measures. For such an effect, we used as case study the Basin of C?rrego Cabu?u de Baixo located at the northwest area of the city of S?o Paulo that, for a long time, was object for punctual interventions with predominance of canalization works and, in the end of the nineties, it counted with the implementation of non-conventional measures that took into account the planning of land occupation and the reservation of pluvial waters. Through the evaluation of this experience we look for identifying the permanencies and ruptures in the treatment related to the subject of inundations. / Nos per?odos de precipita??es, a cidade de S?o Paulo torna-se cen?rio de constantes impactos sociais e econ?micos frente aos preju?zos causados pelas inunda??es. Esse fato est? associado, entre outros motivos, a uma expressiva ocupa??o e impermeabiliza??o do solo e ? ocupa??o das ?reas de risco de enchentes as v?rzeas e fundos de vales. A pesquisa que se segue analisa as diversas concep??es de manejo de ?guas pluviais no ?mbito das reflex?es relativas ?s obras de infra-estrutura e a??es p?blicas destinadas ? preven??o de enchentes. Buscou-se apresentar desde a vis?o higienista do aumento da condutividade hidr?ulica at? a nova vis?o ambiental do manejo sustent?vel da ?gua precipitada, com ?nfase no uso de medidas n?o-estruturais. Nesse sentido, foi utilizado como estudo de caso a Bacia do C?rrego Cabu?u de Baixo localizada na regi?o noroeste da cidade de S?o Paulo que, durante muito tempo, foi objeto de interven??es pontuais com predomin?ncia de obras de canaliza??o e, no final dos anos 90, contou com a implementa??o de medidas n?o convencionais que levaram em considera??o o planejamento da ocupa??o do solo e a reserva??o das ?guas pluviais. Atrav?s da avalia??o dessa experi?ncia busca-se identificar as perman?ncias e rupturas no trato com a quest?o das enchentes.

After an initial analysis of the problems of growth of cities and the exploitation of natural resources, there is a major historical events and documents produced in the environmental area and presentation of a number of changes in the field of architecture and urbanism. There is then an analysis on techniques to improve the environment urban or peri-urban and feel the need to incorporate principles of ecology in planning and city management. The first technical deal with water resources and urban drainage, pointing the principles proposed for sustainable management of rainwater. In addition to these proposals, there is a land of bioengineering and fitorremedia??o, which are techniques for stabilization and recovery of degraded areas, especially in water courses. Shall be analysed then the permaculture, a philosophy that is creating scenarios in human space already offering a number of practices they consider the energy cycle of human actions, aimed at reduction of waste and ecological awareness in food production and actions of everyday life. The permaculture serves as the basis for ecological communities, called "ecovilas", which house thousands of people seeking to live with another form of relationship with nature around the world. The research is finished with considerations of these approaches, relating them and suggesting lines of future study. / A pesquisa baseia-se em uma an?lise sobre as mudan?as que v?m ocorrendo na tentativa de adapta??o das limita??es do planeta frente ?s constantes exig?ncias da humanidade. Ap?s uma an?lise inicial da problem?tica do crescimento das cidades e da explora??o dos Recursos Naturais, ? feita uma retrospectiva hist?rica dos principais eventos ocorridos e documentos elaborados na ?rea ambiental e apresenta??o de algumas mudan?as na ?rea de arquitetura e urbanismo. Apresenta-se, em seguida, uma an?lise sobre t?cnicas que visam melhoria do meio ambiente urbano ou peri-urbano e consideram a necessidade de incorporar princ?pios da ecologia no planejamento e gest?o das cidades. As primeiras t?cnicas tratam dos recursos h?dricos e da drenagem urbana, apontando os princ?pios propostos para um manejo sustent?vel de ?guas pluviais. Como complemento para estas propostas, destaca-se a bioengenharia de solos e a fitorremedia??o, que s?o t?cnicas para recupera??o e estabiliza??o de ?reas degradadas, sobretudo em cursos d??gua. Analisa-se em seguida a permacultura, uma filosofia que vem criando espa?o nos cen?rios humanos j? que prop?em uma s?rie de pr?ticas que consideram o ciclo energ?tico das a??es humanas, visando a redu??o de res?duos e a consci?ncia ecol?gica na produ??o de alimentos e a??es do cotidiano. A permacultura serve de base para comunidades ecol?gicas, chamadas ecovilas , que abrigam milhares de pessoas que procuram viver com outra forma de rela??o com a natureza pelo mundo todo. A pesquisa ? finalizada com considera??es sobre estas abordagens, relacionando-as e sugerindo linhas de estudo futuro.
