Detention Reservoir: Proposal for Flood Control in the Ipiranga Stream Basin, Juiz de Fora, MG, Brazil

In order to provide parameters for sizing a damping reservoir, which was intended to control the floods that occur in the Ipiranga Stream basin, a routine developed in Visual Basic for Applications (VBA) is used. From the identification of the most critical point of the flood, hydrological flow data are presented, estimated by dividing the basin into sub-basins, using the Rational method, resulting in a value of flow higher than the admissible one for the stream channel. The method used in dimensioning the reservoir was flood routing. After making a pre-selection of the most interesting place to position the reservoir, insertions of the situation existent were made to the VBA application, in order to generate scenarios and enable the choice of an ideal situation, in view of the presented constraints. A very acceptable and feasible result is pointed out, indicating general parameters for sizing a reservoir to control floods in the Ipiranga Stream basin
