Vector Representation for the Soil Erosion Model USLE,
This article presents a mathematical viewpoint as vector form on estimating the risk of erosion due to water action, starting from the original USLE. We started with a vector representation of pluviometric regime. Daily amount of rain during a year can be in the form vector graphics. This representation is equivalent to a vector. Starting from this representation is computed the factor of the rain erosivity. We found that other factors in the USLE formula allowed the same type of representation. These representations have been used in the daily calculating for the erosion. This point of view extends the USLE model using to the rainfall event erosivity assessment, similarly with the RUSLE models. This vision permit the comparison between the possible divisions of the annual period: month, weeks, days, hours, minutes or seconds. In this article the solution test are made by comparison of the result with experimental results obtained in the Valea Calugareasca vineyard.
