Noun
erosivity (countable and uncountable, plural erosivities)
A measure of the potential ability of soil, regolith, or other weathered material to be eroded by rain, wind, or surface runoff.
The removal of vegetation increases the rate of surface erosion. citation Topography The topography of the land determines the velocity at which surface runoff will flow, which in turn determines the erosivity of the runoff. Source: Internet
The composition, moisture, and compaction of soil are all major factors in determining the erosivity of rainfall. Source: Internet
Wet, saturated soils will not be able to absorb as much rain water, leading to higher levels of surface runoff and thus higher erosivity for a given volume of rainfall. Source: Internet
