| Resumo: | A type of solution widely used in areas with a predominance of closed drainage basin (basins without outlet) is the implementation of detention and infiltration reservoirs (DIR). This type of solution has the main function cushion the peak flow by storing the surface runoff and to promote soil infiltration. To better understand the operation of the reservoir is necessary the use of mathematical models of rainfall-runoff transformation to determine the project hydrograph and evaluate its operation. In this paper, we proposed studying a small urban drainage catchment, named Experimental Mirassol Watershed (EMW) in Natal, RN, whose outlet is a DIR. The rainfall-runoff transformation process adopted was the Soil Conservation Service model (SCS) and using the synthetic triangular unit hydrograph also from SCS, was determined the DIR project hydrograph. It was verified that the DIR in analysis has the capacity to receive the affluent volume from a rain with return time of 50 years. |
