Seawall
From Coastal Wiki
Definition of Seawall:
A seawall is a shore-parallel hard coastal protection structure at the seaward edge of the land or backshore. It is designed to protect the landward area against wave attack, storm surge, erosion of the landward boundary and, where sufficient crest height is provided, flooding.

Notes
In contrast to most revetments, seawalls are often steep or nearly vertical and may form part of a promenade, quay, boulevard or urban waterfront. Smooth vertical seawalls tend to reflect more wave energy than rough sloping revetments and can therefore produce stronger local turbulence, toe scour, wave run-up and overtopping.
