🌊 Harbour Tide: Two-Component Tide, Dry Flat and Lighthouse Range (2D)

Cross-section of a harbour with a gently sloping tidal flat, a quay, a boat and a lighthouse, followed through the tide. Set the lunar and solar tide amplitudes, the flat slope and width, the lamp height and the quay depth, and see the water level, the area of dry flat, the pressure and force on the quay and how far the light can be seen. Timing, hydrostatics, area and horizon are checked with four in-page numerical checks.
