bore




Also called an eagre, a tidal phenomenon of rivers that widen gradually toward broad mouths, and that are subject to high tides. During spring floods, larger quantities of water from the sea than can normally flow upriver are driven into the rivermouth, resulting in a high wave that travels upriver at great speed. Perhaps the best-known bores are those of the Ganges, the Severn, and the Bay of Fundy. A bore is an example of a soliton.
