Rainfall simulators represent often used equipment for soil research. Depending of their performance they could be appropriate for some soil research or not. The aim of this research is to provide insight into the capabilities of existing dripping rainfall simulators (DRS) to mimic natural rainfall and frequency of simulated rainfalls of certain characteristics, to facilitate the selection of rainfall simulators that would best meet the needs of soil research and to reach step closer to standardization of rainfall simulators. DRS performance was analysed integrally, for simulators with more than one dripper (DRS>1) and with one dripper (DRS=1). A statistical analysis of the performance of DRS, wetted area, drop size, rainfall intensity, duration and kinetic energy (KE) was performed. The analysis showed that DRS can provide rainfall that resembles natural rainfall, except in terms of drop size distribution and wetted area. However, usually there are more factors that do not correspond ...to the natural rainfall, such as median drop size, volume and kinetic energy. The sizes of the drops generated by drippers are mostly in the range between 2 and 6 mm, while the number of drops smaller than 2 mm is relatively small. The intensity and duration of the simulated rain can be successfully produced to match natural values, with the most frequently simulated short-term rainfall of high intensity. The majority of the simulations was conducted at a fall height of up to 2 m; the other experiments were conducted at fall heights that increased from 2 m up to a fall height of 5 m. The KE of the majority of simulations (58.6%) occurred in the range between 20–90% of terminal KE, 33.0% in the range 90–100% and only 8.4% was lower than 20%.
