Because it's not solving for the water surface elevation and velocity, only for light reflection and refraction from a pre-set surface.

The app in the link you posted does indeed look like it's solving at least a shallow water system of equations, and looks very excited to me as a wave physicist.

Completely off topic, but this is a very exciting opportunity for me. What do you do as a "wave physicist"?

[milancurcic]

I study the role of waves in the larger meteorological and oceanographic context, specifically (1) how they govern momentum and energy exchange between wind and ocean currents, and (2) how they contribute to Lagrangian surface transport of pollutants, think oil spills or microplastics.
