JOURNAL FREE ACCESSIn general, the mechanism of sheet erosion is explained that soil partcles are dispersed and carried down by runoff water. This study was done to clear the effect of the impact of raindrops upon the dispersion of soil particles. The soil (Kanto loam) was placed in two tanks, 2 feet by 2 feet and a foot deep. A tank was laid under storms with no protection, and the other was covered with double sheets of wire-gauge (45 meshes) cutting the velocity of raindrops but the same quantity of rainfall as the tank not protected.
The result shaws that the dispersion of soil particles is chiefly caused by the impact of raindrops. If soil is protected from beating by drops, soil loss by runoff water is extremly little.View full abstractDownload PDF (3550K) -

JOURNAL FREE ACCESSForest is most effective on the control of flood and soil erosion, and it is believed that the effect of them depends on mainly the rain interception by canopy and the infiltration capacity increased by the action of root systems. Especially about rain interception many researches was done in the world. But the results of some studies of erosion show that the litter and cover-crops protect soil from erosion by insulating it against the action of falling raindrops. Raindrops beat soil particle into suspension, and the suspended particles clog the pores and openings, and thus materially reduce percoration. By this action water runoff and soil loss increase suddenly.
As a role of rainfall, impact of raindrops is very important on flood and soil erosion.View full abstractDownload PDF (895K) -
