alluvion
River-borne soil accumulation
Alluvion is the gradual accumulation of land along a shoreline or riverbank through natural deposit of sediment.
In legal contexts, land gained by alluvion typically belongs to the adjacent property owner.
The term also refers to the deposited material itself, or to a flood or inundation: The spring alluvion left rich soil across the floodplain.
