ABSTRACT
Splash, overland flow, and rill flow Rainsplash results from raindrops striking rock and soil surfaces. An impacting raindrop com - presses and spreads sideways. The spreading causes a shear on the rock or soil that may detach particles from the surface, usually particles less than 20 micrometres in diameter. If entrained by water from the original raindrop, the particles may rebound from the surface and travel in a parabolic curve, usually no more than a metre or so. Rainsplash releases particles for entrainment and subsequent transport by unconcentrated surface flow, which by itself may lack the power to dislodge and lift attached particles.
