The sudden removal of land from one parcel to another, when a body of water, such as a river, abruptly changes its channel. Contrast with accretion.Example: Because of the change in the river's channel, in Figure parcel A gains use of a portion of the land in the original river bed through avulsion. Similarly, parcel B loses land which is now covered by the river.

The slicing off of a meander, so that the river course becomes straighter, and an ox-bow lake is left behind.

The immediate and noticeable addition to land caused by its removal from the property of another, by a sudden change in a water bed or in the course of a stream.

When a stream that is a boundary suddenly abandons its bed and seeks a new bed, the boundary line does not change. It remains in the center of the original bed even if water no longer flows through it. This is known as the rule of avulsion.

Avulsion is not the same as accretion or alluvion, the gradual and imperceptible buildup of land by the continuous activity of the sea, a river, or by other natural causes.

The tearing away of a structure or part.

• brachial plexus a. — a common injury in dogs and less often cats, usually resulting from trauma that causes extreme abduction of the forelimb and avulsion of some or all nerve roots from C6 to T1. Depending on the extent of injury, the leg may be completely paralyzed with extensive loss of sensation, or if less severe may be carried with only signs of a radial paralysis.
• labial a. — stripping of the lip from its underlying attachments. Lower lip avulsion from the mandible is particularly common in cats. Called also stripped chin.
• phrenic a. — extraction of a portion of the phrenic nerve, producing one-sided paralysis of the diaphragm and partial collapse of the corresponding lung.
