Estudo de alternativas de controle dos problemas de drenagem na região da Feirinha do Tabuleiro, Maceió – Alagoas

Abstract

In order to solve the flooding problems in the Tabuleiro open market region, Maceió - AL, the existing drainage network in the study area was modeled and served as a basis for the intervention scenarios. The first proposed change was the resizing of some structures of the drainage network, according to the hygienist principle, which guided most of the drainage works in the country's large cities in the 20th century. The second scenario analyzed consisted of the implementation of three detention basins to control surface runoff and reduce peak flow. The simulations were developed from hydrological- ydraulic modeling using the Storm Water Management Model program. The scenario that foresaw the resizing of part of the drainage network in the region increased the peak flow at the outlet of the modeled network, while the scenario with the implementation of detention basins was able to dampen the peak flow of the contributing area, in addition to reducing the peak flow at the network outlet. Both scenarios were able to significantly reduce flooding in the most susceptible section of the study area to flooding, but the detention basins did not transfer the problem downstream.
