WebGenerally, small waves cause sediment—usually sand—to be transported toward the coast and to become deposited on the beach. Larger waves, typically during storms, are responsible for the removal of sediment from the coast and its conveyance out into relatively deep water. Waves erode the bedrock along the coast largely by abrasion. Web2.1 Benefits of Vegetation in Preventing Surficial Erosion. Protocols have been developed to describe the factors instrumental in vegetation’s effectiveness in limiting surface erosion. Wischmeier (1975) identified three major sub-factors: (I) canopy, (II) surface cover, and (III) below surface effects.
