| Sumario: | The urbanization process of the last decades worldwide has caused several impacts on the environment, especially in the hydrological cycle, bringing with it an increase in the amount and magnitude of urban floods. The main objective of the present study was to evaluate the impact that the urbanization process of an urban area of the city of Crato-CE has on the surface drainage and to present a proposal for flood reduction through the simulation of infiltration trenches implanted in the public sidewalk receiving waters exclusively from the roofs of buildings. For the simulations, the computer model Storm Water Management Model - SWMM and the computer program UFC8 were used. The results showed that the modeled neighborhood after the total occupation of the buildings and paving of the streets should present problems in the surface runoff of rainwater and that the use of infiltration trenches can considerably reduce the flow peaks. The use of infiltration trenches may have benefits that go far beyond reducing flood problems in the region under study, and may reduce them in other downstream areas and favor the increase of local underground water resources reserves. |
