STUDY OF THE EFFICIENCY OF LOW IMPACT DEVICES IN URBAN DRAINAGE SYSTEMS THROUGH COMPUTATIONAL MODELING
Urban Drainage; LID; Efficiency; Urbanization; Climate changes.
Urbanization and climate change are the factors that most impact urban drainage systems. The combination of these factors implies hydrological changes in the basin that modify the magnitude of urban flooding. As heavy rains are likely to suffer interference from long-term climate change, there is a need to review the design criteria for urban drainage systems, according to expected climatic scenarios and land occupation. In this sense, the most modern approach to stormwater management is low-impact urban devices (LID) that integrate strategically and sustainably into the urban landscape. Despite the several advantageous aspects of this approach, most research generates partial and isolated conclusions about the future behavior of low impact devices with regard to simulations of future scenarios, since climate change and urbanization are not applied together in modeling. Thus, for planning urban development, it is necessary to know the magnitude and behavior of events caused by climate change and urbanization in urban drainage devices, considering the perspective of sustainable alternatives to mitigate flooding. Therefore, the objective of this work is to evaluate the effects of climate change and urbanization on the performance of low impact devices in urban drainage systems.
