(This is also related to influence of continental land masses interfering with the westward movement of tidal bulges and the influence of the Coriolis effect.) The closer to the amphidromic the lower the tidal range. There are about 1 dozen amphidromic points in the oceans (Figure 11.15). A cotidal line is a line on a map connecting points at which a tidal level, especially high tide, occurs simultaneously.

The force driving tides is a combination of the coriolis effect from the Earth’s rotation and the gravity fields of the sun and the moon.

It is possible to visualise the propagation of the tidal wave by mapping the lines of simultaneous high water (occurrence of High Water (HW) in sun hours after moon culmination) and the lines of equal tidal range (vertical distance between HW and Low Water (LW) in m).
