The correlation between the erosivity index EI30 and the rainfall coefficient (Rc) for the period of 1962 to 1981, in Fortaleza (CE), was evaluated to analyze the feasibility of the Rc use to update erosivity values from 1982 to 2000 in this county. An equation that could be used to estimate erosivity in other locations of the coastal region of Ceará State, where there are no rain gauge charts available, was a second aim. A high correlation coefficient (r = […]
