Abstract: The design storm hyetograph plays an essential role in stormwater drainage design. Existing hyetograph models differ in sophistication of theoretical bases. We compare and evaluate four hyetograph models with regards to peak rainfalls and resulting peak flows, using annual maximum storms. In general, the scale-invariant Gauss-Markov model is most favorable for the study area. One attractive feature of this model is that it allows translating hyetographs between storms of different durations.
