During the last two decades, there has been a significant increase in Wind-Driven Rain (WDR) erosion studies, and it is now well known that soil detachment and sediment transport processes differ under WDR conditions compared to those under Wind-FreeRain (WFR). Raindrop motion using the straight-line physics of WFR cannot elucidate that using the vector physics of WDR (Erpul et al., 2013a, 2013b). Accordingly, sub-processes associated with on-impact (splash corona formation or splash detachment) andafter-impact (splash transport) of the WDR erosion also change substantially. On one hand, depending upon the decreases in the compressive stress as lateral jets are well developed, a deep symmetric corona formation becomes much more limited while a shallow asymmetric corona prevails (Erpul et al, 2002). On the other hand, the WDR splash trajectory becomes almost unidirectional in the prevailing wind direction unlike the radial sand splashes of WFR (Erpul et al., 2005).
