luto-, lut-, luv-, lu- +

The phase in liquid-liquid extraction that has a lower concentration of the material of interest.

That which makes something thinner or more liquid by admixture or mixing something else into it.

1. The weakening or reducing the concentration of something by the addition of water or a thinner.
2. A thinning or weakening of a substance, usually a liquid, by the addition of another substance; such as water.

The rate at which populations grow due to births and immigration.

That which can be weakened, made thinner or less concentrated, by adding some other liquid.

1. A reference to or caused by a flood or deluge.
2. Relating to the great Flood described in the Bible.

Pertaining to a deluge, or flood; diluvial.

A deposit of superficial loam, sand, gravel, stones, etc., caused by former action of flowing waters, or the melting of glacial ice.

1. The extraction of one material from another, usually by means of a solvent.
2. A process of removing and separating substances absorbed on a fixed bed by a stream of liquid or gas.
3. A method for removing materials from a mixture through washing, then decanting by pouring off without disturbing the sediment.

1. To purify, separate, or remove (ore, for example) by washing, decanting, and settling.
2. To wash away the lighter or finer particles of; for example, soil.

A method of removing interstitial (narrow space in a rock or soil) organisms from a sediment sample by continuous flushing with water.

1. Composed of or relating to eluvium, fine soil material that has been deposited by the wind.
2. A soil horizon that has lost material through eluviation.

The leached (emptied or drained) upper layer of a soil profile.

A mineral deposit concentrated near the decomposed outcrop of the source and deposited by rain wash, rather than by stream action.

1. The movement of soil material from one place to another within the soil, when there is an excess of rainfall over evaporation.

It may take place downward or sidewards depending on the water movements.

2. The translocation or suspended or dissolved soil material by the action of water; usually the removal of substances in solution is termed leaching (dissolving or passing out by a percolating or passing through a porous substance or small holes) liquid.

Eluviation differs from leaching in that it affects suspended, not dissolved, material and usually results only in the movement of the material from one soil horizon to another.
