Avuision

Avuision [fr. avulsio, Lat.], lands torn off by an inundation or current from property to which they originally belonged, and gained to the estate of another; or where a river changes its course, and instead of continuing to flow between two properties, cuts off part of one and joins it to the other. The property of the part thus separated continues in the original proprietor, in which respect avulsion differs from alluvion, i.e., where an addition is insensibly made to a property by the gradual washing down of the river, for such an addition becomes the property of the owner of the lands to which it is made.
