Theory 24/King tides/Ratio lens
Flood Duration Is Range Against Outfall
The claim
Flood duration is set by the ratio of tidal range to outfall capacity, so a large-range coast drains slowly even with good infrastructure.
01Mechanism
Water can only leave when the tide falls below the outfall; the ratio sets how long that takes.
02Prediction
Duration should track the ratio.
03Refutation
Duration tracking flood volume would remove the outfall term.
