Accretion

Accretion

In international law, this is a generic term for methods by which a State

may acquire title to territory through the gradual operations of nature and requiring no

formal acts of appropriation, e.g., alluvial deposits at the mouths of rivers, significant changes in the course of rivers: The Anna 5 C. Rob. 373 (1805) ; Island of Palmas Case

(1928) 2 R.I.A.A. 829 at 839. If a river is a boundary between States, accretion will alter

the boundary with the erosion and deposit of soil: Louisiana v. Mississippi 282 U.S. 458

(1931) . See I Oppenheim 696 . Cf . alluvion ; avulsion .[1]
