In the figures below Inner Harbour is flooded by an artificial high-tide rendered at increasing intensity, from sea level (low tide at 0 meters) to 10 meters. Two views of the Harbour are shown, first looking from Outer Harbour directly east, and second from Central Harbour looking direct west.

The flooding is a result of a synthetic high-tide that has no real-life analog, because it’s not modeled like a fluid. Unlike the high water mark, this synthetic tide is perfectly flat and follows specific elevation slices (show here in increments of 1 meter). The 3D basin responds in a true or false state whether to render pixels at the tide boundary.
