Which rivers have tidal bores and how many times a year does this phenomenon occur?

The actual lay of the land, the shape, width & depth of the river mouth, and also the coastline features (bay/cove) and approach depth / angle of seabed and wave funneling etc. all determine whether this phenomenon can happen at all. It is effectively "an overflow" condition where the tide will rise faster than the river can smoothly accommodate it. When it reaches a height sufficient to surmount the water already occupying the river, it breaks over and comes rolling in with a steep, high front. Many rivers only demonstate this when tides reach certain high points and so frequency is low, but technically there is nothing to stop this happening as often as twice a day. (ie on every rising tide) 55 worldwide tidal bores with varying information (green ones are links) etc. can be found here: http://tidal-bore.tripod.com/catalogue.html Nov 01 03, 10:06 AM

Everyone does this between 6 and 8 million times per year. What is it? It is a linguistic phenomenon that has been responsible for a number of spelling changes in English words over the centuries, though it does occur in other languages.
