Abstract

The AA. review the erosivity studies conducted in Brazil to verify the quality and representativeness of the results generated and to provide a greater understanding of the rainfall erosivity (R factor) in Brazil. They searched the ISI Web of Science, Scopus, SciELO, and Google Scholar databases and in recent theses and dissertations to obtain the following information : latitude, longitude, city, states, length of record (years), altitude, precipitation, R factor, equations calculated and respective determination coefficient (R2). They found 35 studies, mostly concentrated in the cities of the south and southeast regions that used pluviographic rainfall data to calculate the rainfall erosivity. The lowest values are found in the northeastern region, and the highest values in the north. The rainfall erosivity tends to increase from east to west. The AA. found 73 regression equations to calculate rainfall erosivity in the country
