Tidal bore
|
- Generated in estuaries and rivers with high tidal range and a sharp narrowing and shoaling at the entrance. manifested as a single wave, which may be breaking, that travels along the river or estuary and is followed by a rise in water level. see also bore.
- A phenomenon generated when the leading edge of a rising tide rides over the top of an outflowing river current and moves upstream in the form of a wave. this makes it a true tidal wave (not to be confused with tsunami). these phenomena are relatively rare, occurring only in a few locations where large incoming tides are funneled into a shallow narrowing river via a broad bay. the biggest in north america occurs in the otherwise lazy shubenacadie river, off the bay of fundy where the tidal range is about 12 meters (40 feet). the shubenacadie bore races upstream at a speed as high as 50 km/h (30 mph) and can rise to a height of 5 meters (16 feet) but is usually less. it has claimed the lives of several tourists who were in the riverbed when it came in. the word derives from old norse bara, meaning wave or swell. (also eagre.)

- A broken swell wave travelling shorewards across the surf zone. see also tidal bore.
- A sudden and rapid flow of tide in certain inlets of the sea; as the monstrous wave in the river hooghly, called bahu by the natives, which rolls in with the noise of distant thunder at flood-tide. it occurs from february to november, at the new and full moon. its cause has not been clearly defined, although it probably arises from the currents during spring-tides, acting on a peculiar conformation of the banks and bed of the river; it strikes invariably on the same part of the banks, majestically rolling over to one side, and passing on diagonally to the other with impetuous violence. the bore also
