Flood Tide

The rising phase of the tide between low water and the following high water.

Flood describes changing water level; the associated horizontal flow is a flood tidal stream. That stream may begin or end at a different time from local low or high water and may follow a channel rather than simply flowing directly towards the shore.

A rising tide can increase available depth but can also cover hazards, alter streams and reduce escape time from drying areas. Timing, height and flow should be taken from local predictions and observations rather than assuming every flood provides favourable access or assistance.
