Particle travel distances and bed and sediment compositions associated with rain-impacted flows

Description :
Laboratory experiments were performed with rain of uniform drop size impacting flows over non-cohesive beds of uniform sized sand and coal particles with flow velocities that were insufficient for the flow to entrain the particles without the aid of raindrop impact. Although, in theory, a relationship between settling velocity and particle travel distance exists, particle density is also a factor. Further study of how particle characteristics influence sediment discharge will aid modelling of the impact of the soil in process-based models of erosion by rain-impacted flow.
