Date 1978-04-11 Abstract The paper describes a comparison of calculated storm water discharges with two kinds of rainfall data: design rainfalls developed from intensity-duration-frequency relationships or from measured rainfall data and real measured time series of rainfalls or time series generated by statistical methods. These two rainfall approaches have been compared by simulation of the runoff by a runoff model for a 0.154 km2 catchment area, Bergsjön, in Göteborg, Sweden. Data from two years of rainfall-runoff measurements have been analysed. Different types of design rainfalls have been derived and the 40 heaviest real rainfalls have been selected for simulations. The statistical analysis of the simulated peak flows shows that the real rainfalls give the best results. The conclusion is that the use of design rainfalls give a more uneven dimensioning of storm sewer systems. With real rainfalls it is possible to make a design from a statistical point of view and to find out what happens at discharges with frequencies lower than the design frequency.
