STRUCTURES AND FILLS
In addition to perched beaches, fills can also be incorporated in groin systems and with
breakwaters. In fact, auxiliary fills are almost mandatory in most cases because when such structures fill
by natural accretion, serious erosion problems almost surely occur downdrift.
STRUCTURES AND VEGETATION
While vegetation is one means of controlling shoreline erosion, its most serious deficiency is its
restriction to areas of limited fetch because it cannot establish itself in heavy wave environments.
Vegetation can be used in areas experiencing considerably heavier wave activity, however, if it is placed
in the shelter of a structure such as a breakwater. The use of a temporary structure is particularly
appealing because it protects the plants while they become established and it can be removed later when
the plants mature.
