| In fact they haven't even genuinely summarised even the
| quote they have half-copied. Let alone the article.

| What I find annoying is the tendency to drag half a
| sentence out of context and parade it around as if that
| proves some point.

| They interfere with storm surges. The same way reefs force
| waves to break, dissipating their energy offshore.

|
| Surface waves are only the displacements on the surface that
| we see. The water column is also perturbed below the surface,
| and depending upon on the wavelength and amplitude, the
| perturbation can go down pretty far.
|
| If you track the water particles as the waves pass by, you
| would see the particles traveling up and down and back and
| forth in orbital motions. In shallow water (relative to the
| wavelength), the sea bottom prevents downward motion, so the
| orbital motion is flattened into a back and forth motion near
| the bottom, and near the surface the waves increase height
| and break at the top.
|
| If you have things like coral reefs or oysters (or an
| undersea wall), the back and forth motion is impeded, and
| energy from the wave is dissipated (which reduces the surface
| displacement).
|
| Here's an article on experiments quantifying the energy
| dissipation: https://www.mdpi.com/2077-1312/9/9/1007
