, in See also:engineering, a See also:mound of See also:earth or See also:- STONE
- STONE (0. Eng. shin; the word is common to Teutonic languages, cf. Ger. Stein, Du. steen, Dan. and Swed. sten; the root is also seen in Gr. aria, pebble)
- STONE, CHARLES POMEROY (1824-1887)
- STONE, EDWARD JAMES (1831-1897)
- STONE, FRANK (1800-1859)
- STONE, GEORGE (1708—1764)
- STONE, LUCY [BLACKWELL] (1818-1893)
- STONE, MARCUS (184o— )

stone, usually narrow in comparison with its length, artificially raised above the prevailing level of the ground

Embankments serve for two See also:main classes of purpose
.
On the one See also:hand, they are used to preserve the level of See also:railways, canals and roads, in cases where a valley or piece of See also:low-lying ground has to be crossed
.
On the other, they are employed to stop or limit the flow of See also:water, either constituting the retaining See also:wells of reservoirs constructed in connexion with water-See also:supply schemes, or protecting low-lying tracts of See also:land from See also:river floods or the encroachments of the See also:sea
.
The word embankment has thus come to be used for the See also:mass of material, faced and supported by a stone See also:wall and protected by a See also:parapet, placed along the See also:banks of a river where it passes through a See also:city, whether to guard against floods or to gain additional space
.
Such is the See also:Thames Embankment in See also:London, which carries a broad roadway, while under it runs the Under-ground railway
.
In this sense an embankment is distinguished from a See also:quay, though the See also:mechanical construction may be the same, the latter word being confined to places where See also:ships are loaded and unloaded, thus differing from the See also:French quai, which is used both of embankments and quays, e.g. the Quells along the See also:Seine at See also:Paris
