Question

how does vegetation slow and prevent sediment loss

Answer 1

slows sediment loss because the runoff percentage is a lot less due to a higher infiltration rate. There far the erosion of the soil isn't as predominant in this environment.

Answer 2

Answer:

    The sedimentation consists in the deposition of the particles of the eroded environments.

   Erosion is the process of wear, transport and sedimentation of soil, subsoils and rocks as an effect of the action of erosive agents such as water, winds and living things.

    When soils are “clean”, ie without vegetation (especially in sloping areas), the effects of rainfall and river erosion are more severe.
