Accretion

Accretion is the gradual and imperceptible addition of soil to a riparian or littoral property. The added waterborne soil deposits are known as alluvion or alluvium. Once added to the owner’s property, the accreted soil becomes a part of the owner’s property. If the geological process resulted in the sudden addition of soil to property due to a flood, then there is no change in title. The addition must be gradual, not immediate.
