Influência de Diferentes Parâmetros de Projeto na Concepção de Sistemas de Infiltração de Água de Chuva

Abstract

Conventional and source drainage systems are complementary approaches and proposed solutions to problems arising from excess rainwater runoff in urban areas caused by the increase in impermeable surfaces. However, the conventional system can exacerbate downstream impacts, such as excessive flows, increased pollution, and erosion processes. Conversely, source drainage systems aim to retain and infiltrate water at the precipitation site, reducing surface runoff and promoting sustainability by maintaining the water balance in urbanized areas. Examples of source drainage solutions include infiltration trenches, dry-wells, and permeable pavements, which contribute to aquifer recharge and reduce runoff. This study aims to perform a bibliographic mapping to assess the state of the art regarding research associated with simulations of operational performance and design parameters of source drainage systems. There is a noted lack of specific standards focusing on performance and design parameters to avoid fixed measures and mechanized solutions. The studies highlighted a lack of integration between source drainage systems and building rainwater systems. The growing body of research on compensatory drainage techniques reflects significant Chinese influence, attributed to the implementation of the 'sponge cities' concept and its integration with drainage mechanisms.
