The estimation of design precipitation totals and intensities is an approach for characterising the statistics of precipitation extremes and is widely used in water management practice. In nearly the past 100 years, more than 20 studies have been published on this topic. The aim of this paper is a complex comparison of these studies in terms of both methods applied and the results obtained. We present a chronological review of papers addressing design one-day and multiday precipitation totals as well as sub-daily intensities and compare eight available datasets in terms of the values obtained. Although there is reasonable agreement between the estimates of design one-day precipitation totals, more significant differences exist between the estimates of design sub-daily precipitation intensities, mainly due to the wider range of methods applied and the shorter time series. To further improve the estimates, the authors propose a combination of station-based and radar-based design precipitation intensities.
