This work aimed to update and spatialize the erosivity indices in Brazil based on the most recent climatological normals. The erosivity indices were calculated based on regression equations of 90 pluviographic stations available in the Brazilian territory. Average monthly precipitation data from 1991 to 2020 from 1918 rainfall stations were used. Data were interpolated by ordinary kriging in ArcGis 10.8 (ESRI, 2019) software. The average erosivity was determined for each municipality in the Brazilian territory. The estimated erosivity index varied from values below 1,400 MJ mm ha-1 h-1 year-1 in the Northeast region to values above 17,000 MJ mm ha-1 h-1 year-1 in some points in the extreme North of the Amazon Basin. A strong seasonal variation in erosivity was observed, with a predominance of erosivity in the very high classes in the months of December to March, while in the month of September a very low erosivity value predominates. |
