Trends in rainfall erosivity in NE Spain at annual, seasonal and daily scales, 1955-2006
9 Pags., 4 Tabls., 4 Figs. Rainfall erosivity refers to the ability of precipitation to erode soil, and depends on characteristics such as its total volume, duration, and intensity and amount of energy released by raindrops. Despite the relevance of rainfall erosivity for soil degradation prevention...
