Resumo: Water erosion is a process that consists of the detachment, dragging and deposition of soil particles. The capacity that rain has to cause soil erosion is called erosivity and due to the scarcity of rainfall data in most municipalities, rainfall data is used to determine this factor. The objective was to determine the erosivity through different mathematical models in the municipality of Cacimbinhas - AL. The rainfall data were obtained through the Hidroweb portal, between 1963 and 2000, being tabulated to perform the calculation of rain, rain coefficient and its relationship with erosivity using six equations. The regression was performed using a spreadsheet. The average annual precipitation was 687.01 mm. In 1975, the highest rainfall record was obtained, while in 1998, the lowest precipitation. From April to July the highest rainfall was obtained, and in October and November the lowest rates. The total rainfall coefficient corresponds to 10.88% of the average precipitation in the period studied. For all mathematical models, the highest erosivity indices comprise the months of March to July, while November recorded the lowest index of this factor. The correlation between erosivity and rain coefficient was high for all models analyzed. The erosivity ranged from 246.51 to 4964.13 MJ mm ha-1 h-1 year-1. Between March and July, the highest erosive potential was recorded and, in November, the lowest potential. Mathematical models can be used to estimate the erovisity of rainfall in the municipality of Cacimbinhas - AL.

A capacidade que a chuva possui em causar erosão no solo é denominada de erosividade e devido à escassez de dados pluviográficos na maioria dos municípios, utiliza-se dados pluviométricos para determinação desse fator. Objetivou-se determinar a erosividade através de diferentes modelos matemáticos no município de Cacimbinhas – AL. Obteve-se os dados pluviométricos através do portal Hidroweb, entre 1963 a 2000, sendo tabulados para realização do cálculo da chuva, coeficiente de chuva e sua relação com a erosividade utilizando seis equações. A regressão foi realizada através de planilha de cálculo. A média anual de precipitação foi de 687,01 mm. O ano de 1975 obteve o maior registro pluviométrico, enquanto 1998, a menor precipitação. De abril a julho obteve-se as maiores precipitações, e, outubro e novembro os menores índices. O coeficiente de chuva total corresponde a 10,88% da média de precipitação no período estudado. Para todos os modelos matemáticos, os maiores índices de erosividade compreendem os meses de março a julho, enquanto novembro registrou o menor índice deste fator. A correlação entre a erosividade e o coeficiente de chuva foi alta para todos os modelos analisados. A erosividade variou de 246,51 a 4964,13 MJ mm ha-1 h-1 ano-1. Entre março a julho registrou-se o maior potencial erosivo e, em novembro, o menor potencial.
