“…The angle of inclination of the leaf to the falling raindrops influences the proportion of the original kinetic energy retained by the drop after contact (Schottman, 1978), the tendency of drops to shatter or to coalesce (Kitanosono, 1972) and the direction taken by the rain, whether towards stemflow or temporarily intercepted throughfall. The measure of the angle of inclination adopted in this study was that of the leaf petiole to the main stem.…”

Rates of splash detachment from a sandy soil of the Cottenham Series, subjected to a five-minute design storm of 50 mm/h with a kinetic energy of 127 J/m2 and a median volume drop size of 3.2 mm supplied from a rotating-disc rainfall simulator, are determined without a plant cover and with the cover of a single Brussels sprouts plant. Measurements are made at regular intervals throughout the growing season. Plant canopies of 10 to 25 per cent result in reductions of 10 to 25 per cent in rainfall volume and 10 to 81 per cent in rainfall energy. The volume and energy of the rain beneath the plant are significantly (P< 0.05) correlated with its number of leaves ( r = -0.84 and -0.92 respectively for n = 49). No reduction was observed in the rate of splash detachment which averages 1.2 kg/m2 for the design storm with and without the plant. The detachment rate was found rather surprisingly to be inversely related to the energy of the rainfall under the plant and positively related to the number of leaves. As the number of leaves increases, so does the detachment rate per unit of rainfall energy.
