Polski🌊 Harbor Tsunami Defense: Shallow-Water Shoaling & Breakwater Transmission (2D)
2D cross-section tsunami lab: a finite-difference shallow-water-equation solver on a real shelf-to-harbor depth profile, showing wave shoaling (Green's law) and a breakwater with an adjustable engineering transmission coefficient.
This 2D companion replaces the 3D scene with the cross-section the coastal-engineering math actually lives in: a leapfrog shallow-water-equation solver runs on a real shelf-to-harbor depth profile, a wavemaker drives a true tsunami-period wave train shoreward, Green's-law shoaling emerges from the physics as depth falls, and a breakwater at the harbor mouth attenuates the incoming wave by a live, freeboard-and-gap-driven transmission coefficient — so every slider visibly changes both how much the wave amplifies and how high it floods the harbor quay.
