alluvion - Legal Definition
The creation of land caused by the gradual depositing, either by artificial or natural forces, of earth, sand, gravel, and similar materials along the shoreline of a river or ocean by running water. The new land becomes the property of the owner of the property to which it is attached, provided the accumulation is so gradual that it cannot be visibly perceived from moment to moment. See also accretion, reliction, alluvium, and avulsion.
