Infraestrutura verde urbana como solução para áreas vitimadas por alagamentos

Abstract

Flooding problems result from natural phenomena of hydrological character caused by fast and strong rains of long duration. However, there was an increase in the frequency of such events due to the changes caused by human action on the environment where he lives. The intense urbanization process, lacking an adequate land use and occupation planning along with the massive soil waterproofing, besides modifying the intensity and distribution characteristics of rainfall, also contributes to the occurrence of flood episodes. Sustainable urban drainage preserves the natural system of stormwater infiltration by developing green infrastructure models, which proposes the addition of natural stormwater infiltration into the soil and increased runoff delay through permeable pavements, rain gardens, biowalves, green roofs, stormwater trenches, wetlands, underground storage, among others that alter according to the region to be revitalized. The implementation of the green infrastructure is a possible solution to mitigate the effects caused by urbanization and solve the problems of urban flooding. The results found in related works were promising indicating the reduction of flood cases, as well as an adaptation to the living environment, providing a better quality of life to the residents. In this work a case study was developed with the application of the green infrastructure.
