Definition of Seawalls and revetments:
Seawalls and revetments are shore parallel structures at the transition between the low-lying (sandy) beach and the (higher) mainland or dune.
The height of a seawall fills often the total height difference between beach and surface level of the mainland. In many cases adjacent at the crest of a seawall a horizontal stone covered part is present (e.g. boulevard; road; or parking places). At the initial time of construction a seawall is situated close to the position of the dune foot. In the present discussion with a seawall an almost vertical structure is meant. The seaward side of the seawall is thought to be rather smooth. A revetment is similar to a seawall, but often sloping.This is the common definition for Seawalls and revetments, other definitions can be discussed in the article
