Análisis de la erosividad de la lluvia en Isla de Margarita (Venezuela) a través de datos de precipitación horaria

This work presents/displays an analysis of the erosive of rain taking a series from indicators that take like data the values from precipitation on hour scale, all it, in the geographic space that corresponds to the Isla de Margarita; located insular space to the Northeast of Venezuela. These collected data of the pluviografic registries of the climatic stations: Boca de Pozo y La Guardia during the period of study of eight years (1998-2006). In function to this objective a documentary revision of the thematic one was made to treat and later on the basis of a geographic characterization of the area in study it was developed to the calculation and analysis of erosividad; I30 Of Castro Filho and EI of Lo et al, where each hour data was considered a rain segment, all with equal duration of 1 hour and as Maxima intensity in 30 minutes considered the hour segment with greater amount of rain. From the results it was managed to identify, to explain and to differentiate the characteristics from the erosive events, in addition that were conducted to represent their narrow relation with the intensity and estacionalities of precipitations in the period of 1998-2006 on the area in study; managing in addition to make analysis that allowed to know that on the area the erosive events most frequently appear in the rainy months during the hours of 1:00 p.m. to 9:00 p.m. appearing these with a precipitation average of 23,50 mm and one intensity per 16,208 hour of mm/hr and is reflected finally, that the indices of Castro Filho and Lo et al keep certain correlation with the annual rainfall.
