ResumenInformation from 152 experiments of rainfall simulation was jointly analysed. The study was done in 17 land uses with contrasted vegetation cover situations from 4 geographic contexts (NE Catalonia, high and medium lands from the Ebro Valley and Southern range of Central Pyrenees). Experiments were done using similar rainfall simulators, with the same spray nozzle, spraying components and plot size, with a wide spectrum of precipitation intensities. Results showed significant differences in runoff amounts and erosion rates, which were mostly associated with land uses, even more than precipitation differences. In fact, even though the highest rainfall intensities were applied in the most natural areas with dense vegetation cover, the most intense responses were produced in the most altered environments. These results agreed with the causedeffect relationships observed in some antecedent studies. Likewise, this analysis has provided comparable information between environments, allowing estimate proportionally factors and favouring their classification.
