Using a rainfall simulator, 22 rainstorms with varied intensities from 30 to 117.5 mm h−1 and return periods from 2 to 127 years were reproduced. The experimental plots were installed on vineyards planted in straight rows and oriented with the slope direction having a mean gradient of 3.8°. The texture of soils was loamy, with a very heterogeneous surface gravel cover. Values of measured surface runoff varied from 7.2 mm h−1 for low rainfall intensities (30 mm h−1) and short return periods (2 years) to 41.9 mm h−1 with simulation experiments of higher rainfall intensity (104 mm h−1) and long return periods (68 years). Runoff increased linearly with rainfall intensity resulting in soil losses that also increased with rainfall intensity (18.2 g m−2 h−1 with storms of 30 mm h−1, and 93.2 g m−2 h−1 with storms of 104 mm h−1); however, r2 explains only 36% of the variance. It was necessary to add other factors to improve the coefficient of determination (0.74; p = 0.001) and the predictive function of the equation. These variables were rainfall intensity, kinetic energy of the storm, runoff, soil resistance to drop detachment, surface gravel cover, and gradient. The equation obtained was validated with the USLE-M. In comparison with similar experiments in other regions, the results obtained for soil loss were very moderate, especially those caused by rainstorms of intermediate and low intensity. | Descripción: | 11 páginas, 7 figuras, 9 tablas. | Versión del editor: | http://dx.doi.org/10.1016/j.still.2006.05.013 | URI: | http://hdl.handle.net/10261/35323 | DOI: | 10.1016/j.still.2006.05.013 | ISSN: | 0167-1987 |
