Knowledge of the erosive potential of rainfall and its distribution throughout the year contribute to planning management and soil conservation practices that aim to reduce water erosion, decreasing soil loss and increasing crop yields. The goal of this study is to characterize rainfall in the region of Urussanga, SC, Brazil, in relation to its erosive potential, determining monthly and annual Erosivity Indices (EI30), thus establishing the R factor to use in the Universal Soil Loss Equation. In addition, the goal […]

Water/Hydro-erosion comes as a result of rain erosivity and soil erodibility. Knowledge on erosivity is therefore useful as a guide for recommendations on management practices and soil conservation which have the aim to reduce hydro- erosion. Objectives of this study were the factor identification and quantification of natural rain erosivity in Lages, Santa Catarina, as well as knowledge on its temporary distribution. The study was carried out in 2000, using data on rainfall and soil loss of the period from […]
