High intensity rainfall creates serious risk as heavy drops on bare soil causes the soil surface to seal

Nature of the soil (erodibility)

Clay soils vary in their ability to withstand raindrop impact slope length—if a slope is long, water running down the slope becomes deeper and moves faster, taking more soil with it

Slope steepness

The speed of runoff increases on steep slopes, which increases the power of water to break off and carry soil particles.
