Resumo

Unrestrained and unplanned urban growth promotes significant impacts to the environment, generating, for example, soil sealing and increasing surface runoff. Consequently, there is also an increase in the occurrence of urban floods, and there is a need of acts to minimize the disturbances generated. In the city of Joinville-SC, the scenario is not different. The Cachoeira River Basin, the main basin located in the urban part of the city, suffers the impacts generated due to unplanned growth. As a result of this problem, the present paper proposes the pre-dimensioning of detention reservoirs (structural control measure), performing the delimitation of its contribution basins, using the SCS and Müller-Neuhaus methods for return periods of 2, 5, 10, 50 and 100 years. An analysis was made of the functionality of these reservoirs for the different return periods mentioned above.
