If the max flow is when the height distance is the greatest, wouldn't
the tide change wave be like a pyramid instead of a sine wave?


Thom
Max flow is most likely when the _rate of change_ of height is fastest.
This is most likely at half tide in the open sea, but there is no firm
rule for this hence my *most likely*. The current due to tides is also
summed with other currents for example.
