Erosivity estimation in the province of Manabí with the CORINE method.

Abstract

An important aspect prior to the calculation of erosion is Erosivity. In the present work the objective is to undertake a spatial estimation of Erosivity in Manabí province with the CORINE method. This method calculates Erosivity by integrating two climatic indices: the Modified Fournier Index (MFI), and the Bagnouls Gaussen Aridity Index (BGI). Rainfall and temperature reports from nine locations in of the province are used. In average, 8 years of data are used for each station. Results of MFI and BGI vary spatially, but coincide to a great extent with the distribution of climates in the province and a variable Erosivity in the territory.
