Also found in: Dictionary, Thesaurus, Medical, Financial, Encyclopedia, Wikipedia.
The act of adding portions of soil to the soil already in possession of the owner by gradual deposition through the operation of natural causes.
The growth of the value of a particular item given to a person as a specific bequest under the provisions of a will between the time the will was written and the time of death of the testator—the person who wrote the will.
Accretion of land is of two types: (1) by alluvion, the washing up of sand or soil so as to form firm ground; and (2) by dereliction, as when the sea shrinks below the usual watermark. The terms alluvion and accretion are often used interchangeably, but alluvion refers to the deposit itself while accretion denotes the act. Land uncovered by a gradual subsidence of water is not an accretion; it is a reliction.
