remoun.

Brit.

/rəˈmuː/, U.S.

/rəˈmu/

Forms: 1800s– remous, 1800s– remou.

Origin: A borrowing from French. Etymon: French remous.

Etymology: < French remous tumult, agitation (late 14th cent. in Middle French), turbulence created in the wake of a moving boat (1687 as remoux ), swirling of a liquid around an obstacle (1765), apparently < remoudre to grind (something) again (although this is first attested later: 1481 as remouldre ; < re- re- prefix + moudre : see muller n.¹), apparently arising from a comparison of the swirling movement of the water with the rotating movement of a grindstone.

†1. A part of a flow of water where the water level is raised or the flow altered as a result of an obstruction. Obsolete.

1780 Philos. Trans. 1779 (Royal Soc.) 69 607 There are..two different and opposite currents in the river; that whereby the waters flow towards the sea..and that of the waters which remount, either by the flowing of the tide, or by their meeting with local obstacles, which form a counter current... This counter current is what the French call a remous.]

1852 G. R. Burnell Rudim. Hydraul. Engin. III. 61 It may..be as well to adopt the French phrase ‘remous’ to express the increase of height and the change of direction produced in a current by the intervention of any obstacle... The greatest depth of the remous..will exist immediately over the edge of the dam.

1858 J. Bennett tr. J. F. d'Aubuisson de Voisins Treat. Hydraul. ii. ii. 176 Subtracting from this depth that of the primitive current, we shall have the height of the remou or flow.

1865 Amer. Jrnl. Sci. 89 155 The water is sufficiently high to flow over the dam without much remou.

1889 Trans. Amer. Soc. Civil Engineers 20 31 The back-water curve or ‘remous’ caused by accretions at the lower manhole would practically not extend up to the upper manhole.

2. An area of turbulence in a stream, an eddy; (also) a region of turbulence in the air (now rare).

1858 J. Bennett tr. J. F. d'Aubuisson de Voisins Treat. Hydraulics ii. ii. 174 A remou, or eddy, in the strict acceptation of the word, is water without progressive motion..which turns back on itself.

1889 Scribner's Mag. May 531/1 They are..going out on the tops of the long glassy rollers at the tail of the main eddy into the white water of the main current, which carries them back again to the other end of the remou.
