How fast does the tide roll in?
I heard someone on TV say the tide moves as fast as a galloping horse. I found that hard to believe so I did a search on Yahoo, asking how fast does the tide roll in? After looking through 10 pages of matches pertaining to Alabama's Crimson Tide, I gave up. YA should be faster.
So, does anybody here know how fast the tide rolls in? Is it the same speed everywhere? If it's like a galloping horse, it sounds more like a tsunami.
If an unsuspecting tourist who's unfamiliar with the sea, and the tides, hears or sees it coming can he outrun it?

You need to look up tidal bore. A tidal bore moving up a stream can indeed travel at the speed of a galloping horse.

very much a function of the location. Tide is essentially a result of a vertical change in water level. The tide comes in or goes out because the ground slopes to varying degrees. There are places where the tide can move quite rapidly because the ground is almost level in the tidal flat AND the structure of the coast concentrates the water into that area. There are places like in the Bay of Fundy (between Nova Scotia and New Brunswick) where you can see the tide move and in places it will move faster than you could run. It can be very hazardous.
A cliff face will see no inflow outflow of tide, just a rise and fall. A long tidal flat or shallow bay will see rapid movement.
