Changing needs of the society also change the goals of hydrological calculations. The “design storm” concept cannot provide adequate answers to the complex problems on many time scales that society is facing today. This paper present a novel approach to generate artificial rain data with a time resolution sufficient for urban hydrology. The model is based on Wolds process of intervals, ie. it generates waiting times observed at a tipping bucket gauge conditional on the previous waiting time. The model is verified both with respect to average and extreme values and by testing it on urban drainage problems and it is concluded that the model appears to have captured to properties of rainfall well.
