Simulation of the size distribution and erosivity of raindrops and throughfall drops

Abstract: This paper presents a model that simulates the size distribution and erosivity of raindrops and throughfall drops. It utilizes existing models of rainfall drop size distribution and fall velocity and combines them with newly collated evidence of throughfall drop size distributions. A sensitivity analysis reveals that the model is sensitive to parameters that are easily measured or estimated: rainfall intensity, the mean volume drop diameter of the intercepted throughfall, canopy cover, and canopy height.The re… Show more

“…Ink blotters dusted with potassium manganese used by Anderson [12] and known water densities used by Abudi et al [13], incorporated weights of raindrops to infer size. Several studies [14][15][16][17][18][19][20][21][22] used Whatman's No. 1 filter paper, which was identified as yielding the most accurate results.…”

“…Soil detachment by rainfall occurs when raindrops fall directly onto ground surface with sufficient kinetic energy to detach soil particles from the surface. Because canopy cover changes the kinetic energy of raindrops by initializing raindrop velocity and altering raindrop size [44], rainfall has a different impact on areas under and without canopy cover. Grounds without canopy cover are affected by the raindrops falling directly onto the bare soil (direct throughfall).…”

“…Para cada uno de los eventos lluviosos se estimó la intensidad má-xima a 30 minutos (I30), y la energía cinética (KE = 210 + 89 log10 I) (Wischmeier y Smith 1978, Brandt 1990). El índice de erosividad para cada evento se calculó multiplicando la energía cinética por su intensidad máxima (Wischmeier 1976 Se realizaron análisis de correlación (p < 0.01) para evaluar las relaciones entre la erosión y escorrentía, con las propiedades de los eventos de lluvia y el grado de protección del suelo.…”
