The objective of this work was the evaluation of the urban drainage system of Residential Park Alto da Colina, which presents flood points during high storms, using monitoring data. Through the use of rainfallrunoff and hydrodynamic 1-D model, included in the package MOUSE v.2003, current problems concerning the inefficiency of the drainage system and aiming solutions for the urban drainage planning in the area were analyzed. In the calibration stage the software present satisfactory results, with average correlation coefficient of 0.94 and average errors in the peak and volume flows of 4.24 and 19.28%, respectively. In the comparison between observed and simulated flood levels in streets of two registered events, errors of -24.88% and -9.19% were obtained. The simulations with design hyetographs allowed evaluate the critical points of the network system, besides the mapping of streets with flood problems. As alternative of control floods intended the adoption of some structural measures, with the network resizing and introduction of a detention reservoir in the rural area of the basin. The simulations of the control alternatives showed that the proposed measures are effective and viable in the flood control.
