WATER DEPTH ANALYSIS IN THE ADOPTION OF SUSTAINABLE URBAN DRAINAGE TECHNIQUES WITH THE APPLICATION OF COMPUTATIONAL MODELING AND GIS SOFTWARE FOR A RESIDENTIAL NEIGHBORHOOD

Abstract

Abstract: The increase in the world's urban human population generated of the scarcity of natural resources. Then, to minimize local drainage problems caused by unplanned urbanization, this paper proposes to analyse results simulated using compensatory measures in the Imboassica neighborhood, city of Macaé, State of Rio de Janeiro, Brazil. It objectives assess the model's response to different choices of Coefficient of Manning and Curve Number. In addition, It compares the influence of the height of buildings and roads on the distribution of water in space. This paper uses the MOHID Platform by means of the OpenFlows Flood© software to simulate 10 and 50 years return period Rain Design for the studied region. It simulated the adoption of Compensatory techniques in sustainable urban drainage, the use of green roof and permeable pavement. The changes adopted for different uses of the territory were described using the QGIS© software. It was possible to conclude that the difference in the water depth decrease ranges from about 11.1% and 14.3% because of adopting the compensatory measures for the 50 and 10 years return period Rain Design, respectively. Another evaluation performed was the change of the topography data, considering information of the height of buildings and the roads.
