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, otherwise serious erosion
problems can 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 become established in heavy wave environments.
Vegetation can be used in areas experiencing considerably heavier wave activity, however, if it is placed
in the shadow of a structure such as a breakwater. The use of temporary structures is particularly
appealing because they provide protection while the plants need it, and can then be removed later when
the plantings have matured.
