Rainfall erosivity at Teodoro Sampaio was studied through methodology proposed by Wischmeier and Smith (1958). A set of 812 erosive individual rains was selected, from a continuum series of nineteen years of nonrecording rain gauge data, according to Wischimeier (1959), Wischmeier and Smith (1978) and Cabeda (1976) and proposed with changes by Carvalho (1987). All the selected rains were computed by the package of Cataneo et al. (1982). The rainfall erosivity factor computed was 7172 MJ mm ha-1 h-1 y-1, […]
