A stream changes its channel, resulting in land being removed. This phenomenon is known as what?

The situation described in the question involves a stream changing its channel, which leads to the removal of land. This phenomenon is known as avulsion. Avulsion specifically refers to the sudden and rapid change in the course of a river or stream, which can result in the loss of land in one area and potentially the creation of land in another. It is characterized by a swift and dramatic alteration, unlike gradual processes of land alteration.

Understanding avulsion is critical in the context of property law and land ownership, as it can have significant implications for property boundaries and ownership rights. When avulsion occurs, the affected landowners must navigate the legal considerations arising from these sudden changes, including how the loss or gain of land impacts their property titles and interests.
