breakwater
Let an agent explain breakwater types and design, describe their role in ports and coastal protection, support safety questions, and describe environmental effects.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain breakwater types and design, describe their role in ports and coastal protection, support safety questions, and describe environmental effects.
A structure built offshore or from the shore to protect a harbour, anchorage or coastline from wave action, constructed from rubble mound armourstone, concrete units, caissons or sheet piles, either emergent or submerged, attached or detached; breakwaters create calm water for ports and beaches and are designed by coastal engineers to withstand storms and manage sediment.
What it is for: Protecting harbours and shores from waves.
It can be explain breakwater types; describe design and construction; give safety guidance; describe environmental effects.
Distinguishing features
Wave attenuation
Rubble or concrete construction
Emergent or submerged
Port and coast protection
What it looks like
A long mound or wall of rock or concrete extending into the sea.
How it is recognised
Wave-protection structure
Offshore or from shore
A groyne runs perpendicular to the shore to trap sand; a seawall protects land directly
