                         aim of the present work was to evaluate the feasibility of using 
                         rain based on meteorological radar data from the Institute of 
                         Meteorological Research of Bauru (IPMet / UNESP) in the 
                         implementation of the simplified distributed hydrological model 
                         Soil Conservation Service -Curve Number (SCS) -CN), an end of 
                         analysis or runoff of events in the Jacar{\'e}-Gua{\c{c}}u River 
                         watershed, located in the central-eastern region of the S{\~a}o 
                         PauloState. In this work, how to display rain from IPMet weather 
                         radar data was calibrated with data from 18 rainfall stations, 
                         however, a study area has only one fluviometric station in 
                         operation, located outside the basin. Two events that took place 
                         in January and February 2013 were selected, according to the 
                         spread runoff extracted from the application of a digital runoff 
                         selection filter. The results were satisfactory aboutthe 
                         propagation of runoff generated by the hydrological model SCS-CN. 
                         However, it should be noted that some factors of uncertainty were 
                         taken into account in the process of implementing the hydrological 
                         model. One of these factors is the lack of calibration of the 
                         parameters of the SCS-CN model, such as the tabulated values of 
                         the CN, which may produce some spurious data of the effective rain 
                         and, consequently, this may have interfered with the values of 
                         propagation of the runoff.",
