| TIDAL BORE. |
I always like to receive these "Did you Know " cards and this one is from New Brunswick in Canada.
"THE TIDAL BORE" A rare curiosity called a "BORE" is formed by the Bay of Fundy on The Petitcodiac River in Moncton, N. B. and The Salmon River, Truro, N.S. Each River emerges from the Bay, gradually narrowing and becoming more shallow,As The Tidal current enters this more confining region the waves steepen because the wave crest ( Foamy top ) is moving faster than the trough ( foot of the wave ) and finally the crest overtakes the trough and the wave breaks..It then continues up the River in a surge, sometimes the wall of water is minimal and only a few inches highbut in the Spring tides it can reach a few feet. The height is determined by the depth of the Tidal Water which in turn depends on the Phases of the Moon. This explains the difference in the size of each Tidal Bore... I have witnessed such a large Tidal Bore in The Western part of the UK in The River Severn ,where, when this bore races up the river some people surf the large wave for miles..
Thank you Ruby for swapping this card..
