Simulation of surface runoff in neighborhoods in the urban area of the city of Macaé, Rio de Janeiro, Brazil

Considering the high prevalence of flooding in the city of Macaé, the main objective of this work was to analyze the behavior of the river basin that encompasses the Praia Campista and Imbetiba neighborhoods to provide support for urban managers in projects and in the establishment of public policies focused on water resources. To achieve this, it was necessary to develop the delimitation of the hydrographic basin of the urban region that encompasses the Praia Campista and Imbetiba neighborhoods in the city of Macaé; simulate surface runoff in the region delimited by the river basin; obtain water depth data in the natural channels simulated in the model and; obtain water depth data at previously determined points in the river basin. As a result, it was possible to monitor and determine the water depth value, representing the surface runoff in the river basin, and the depth in the drainage channel of predetermined regions.
