weir


weir
/wear/, n.
1. a small dam in a river or stream.
2. a fence, as of brush or narrow boards, or a net set in a stream, channel, etc., for catching fish.
[bef. 900; ME were, OE wer, deriv. of root of werian to defend, dam up]

      any control or barrier placed in an open channel to permit measurement of water discharge. The latter may be computed from a formula expressing the discharge in terms of crest length of the weir, depth of flow above the weir, weir geometry, and other factors. A variety of weirs have been used in streams, the so-called sharp-crested and trapezoidal forms being relatively common; but broad-crested, triangular, and contracted weirs are also favoured in certain circumstances. Spillways, controls, and embankments designed to permit discharge measurements are simply different kinds of broad-crested weirs.
