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.

They then compared the requirements to specific existing accretion models, which have predicted specific power and mass flow rates.
They cover mass and spin evolution of super-massive black holes, accretion and outflows, jets, news from the gamma-ray sky, feedback from AGN, and the radio-loud/radio-quiet dichotomy.
These methods and other ones under development assures for the rapid prototyping by material accretion an increasing rate of its diffusion, the spread of these new methods into the broader market place, and of its infusion, the process of developing applications of these new methods to their maximum potential.

Results: Calcium supplementation significantly influenced bone accretion in young females during the pubertal growth spurt.
If strata are correlative from one to the other, such relationships may indicate there was no major terrane; if they are not correlative, the accretion boundaries are cryptic.
According to Karpat, "The genesis of Turkish nationalism was a multifaceted process occurring in several stages of identity accretion proceeding from universal Ottomanism and Islamism to specific ethnic Turkishness and Turkism"(13).
Although this accumulation is most conspicuous in the tonsils, progressive accretion of these esters also occurs in nerves (neuropathy) and vessels (atherosclerosis).
