avulsion (redirected from avulses)

Avulsion

In law, a situation in which the amount of land on a property increases or decreases due to a sudden (not a gradual) action of water. For example, a flood changing the course of a river may result in avulsion. Depending on the laws of the jurisdiction in which it occurs, an avulsion may or may not change property lines or even government borders.

avulsion

A sudden and perceptible loss or addition to property as a result of the action of water either taking soil from one property and leaving it on another,or by virtue of a river or other running water changing the course of its bed.The rule is that boundary lines described with reference to the midpoint of the stream will remain at the midpoint of the old stream, and not the midpoint of the new stream. This is because of the sudden nature of the change, so that people may reasonably notice and mark the location of the old stream bed as a matter of reference.
