eluviation (s) (noun), eluviations (pl)
1. The movement of soil material from one place to another within the soil, when there is an excess of rainfall that is much greater than evaporation: Eluviation may take place downward or sidewards depending on the water movements.
2. The translocation of suspended or dissolved soil material that exists as a result of the action of water: When nature causes the removal of substances with water, they are termed leaching liquids. That means that they are dissolved by passing out by means of percolating or passing through porous substances or small holes, however eluviation differs from leaching in that it affects suspended, not dissolved, material and it usually results only in the movement of the material from one soil height to a different level.
