Analysis of rainfall erosivity associated to pluvial precipitation patterns in the Ribeirão das Lajes region, Rio de Janeiro state, Brazil
01/Oct/2008
The rainfall characteristics determine erosivity, which is an important factor in the cause – effect relationship in soil erosion. The characterization of rainfall is therefore of fundamental importance for conservation planning. The present study aimed to evaluate the distribution of rainfall characteristics (depth, duration, kinetic energy, maximum intensity in 30 min) and erosivity indexes (EI30 and KE > 25) in relation to the months of the year and to precipitation patterns for a series of pluviographic data in the region of Ribeirão das […]
