Rainfall erosivity for Pantanal biome

Compartilhe:
Abstract:

The scarcity of pluviograph data in the Pantanal zone forced many researchers to use regression equations obtained in others regions of Brazil to calculate the R factor of Universal Soil Loss Equation (USLE). This study defines a model to predict the erosivity of the Pantanal Biome correlating the calculated rainfall erosivity index EI30 and the rainfall coefficient (Rc). The model showed a significant correlation with the observed data, yielding coefficient of determination of 97%. Therefore, the rainfall erosivity model proposed can be used to estimate the R Factor of USLE data from monthly and annual precipitation for the region and other regions with similar climatic characteristics.
