Ownership and Land Use, 15% of the examination
Accretion
The gradual deposit of soil along a watercourse, adding to the owner's land.
The soil deposited is called alluvion and the riparian owner takes title to it. Avulsion is a sudden change, such as a river jumping its bank in a flood, and it does not move boundaries. Reliction is the gradual withdrawal of water exposing land. Erosion is gradual loss.
