Tidal Bore Truro N.S., Canada

What is a Tidal Bore. Well at most places along the ocean shores, high tides occur regularly every 12 hours, 25 minutes. In the open ocean the tide only rises and falls a fraction of a meter. However, in most V-shape bays and inlets the tide enters the broad end and the water literally "PILES UP" as it moves up the bay. At the very head of the bay this advancing tide becomes a wave varying from just a ripple to several feet in height and this wave continues in and up the rivers which empty into the bay. This wave is referred to as the "TIDAL Bore". You can see this wave coming in around the corner in the photos. Water keeps coming in until tide is high.
