• Abstract:

  This work aims to evaluate a specific methodology for the implantation of microreservoirs in urban lots in the neighborhood of Tijuca, in the city of Rio de Janeiro, based on hydrological and hydraulic modeling with the SWMM software. The methodology consists of selecting micro-drainage areas and assessing the operating conditions of existing drainage networks, with and without the use of detention micro-reservoirs in the lots. The results indicate potential flood dampening with an average reduction of 37% in peak flows in the studied network for a fully urban basin with no affluence from adjacent sub-basins.
