THE FUNCTIONS OF GREEN ROOFS IN THE URBAN ENVIRONMENT AND THE MANAGEMENT OF WATER RESOURCES

LAS FUNCIONES DE LOS TEJADOS VERDES EN MEDIO URBANO Y EN LA GESTIÓN DE LOS RECURSOS HÍDRICOS

RESUMO
A ocupação desordenada em áreas urbanas vem causando diversos problemas, entre eles, as inundações, provocadas pelas chuvas intensas que aliado aos altos níveis de impermeabilização do solo, resulta em grandes prejuízos sociais e ambientais. Nesse contexto, a utilização do telhado verde surge como técnica compensatória, restaurando as condições hidrológicas anteriores as ocupa¬ções urbanas e reduzindo significativamente o pico do escoamento da maioria das precipitações. Dessa forma, a pesquisa tem por objetivo apresentar uma síntese dos principais pontos que devam ser observados na utilização do telhado verde sob o ponto de vista da minimização de alguns dos impactos da urbanização no ciclo hidrológico e nos recursos hídricos. A metodologia adotada neste estudo partiu de uma pesquisa bibliográfica, baseando-se na abordagem sistêmica, com o intuito de reunir diversas análises interdisciplinares sobre os efeitos dos telhados verdes, relacionando-os com diversos fatores. Como resultado constatou-se que a mesma pode ser considerada como um sistema sustentável de drenagem pluvial urbano, por meio do aumento de áreas de infiltração, percolação, receptação e armazenamento temporário de águas pluviais, devendo, portanto, ser inserida nos planos de gestão das cidades como ferramenta para o controle quantitativo do escoamento superficial na superfície urbana, reduzindo o volume das águas pluviais e servindo de instrumento de prevenção a enchentes.

ABSTRACT
The disordered occupation in urban areas has caused several problems, among them, floods caused by heavy rains that, together with the high levels of waterproofing of the soil, result in great social and environmental damages. In this context, the use of the green roof appears as the compensatory technique, restoring the water conditions prior to urban occupation and taking advantage of the peak of the flow of most precipitations. Thus, the research aims to present a synthesis of the main points that should be observed in the use of the green roof under the aspect of minimizing some of the impacts of urbanization on the hydrological cycle and water resources. The methodology adopted in this study was based on a bibliographical research, based on the systemic approach, with the purpose of gathering several interdisciplinary analyzes on the effects of green roofs, relating them to several factors. It was verified that it can be considered as a sustainable system of urban stormwater drainage, through the increase of areas of infiltration, percolation, reception and temporary storage of rainwater, should therefore be included in city management plans as a tool for the quantitative control of surface runoff on the urban surface, reducing the volume of rainwater and serving as a flood prevention instrument.

Keywords: Surface runoff; Green Cover; Environmental Management; Hydrological Cycle.
