A dam in a waterway over which water flows and that serves to raise the water level or to direct or regulate flow.

In hydrologic terms, (a) A low dam built across a stream to raise the upstream water level (fixed-crest weir when uncontrolled); (b) A structure built across a stream or channel for the purpose of mea [..]

A low dam built across a stream to raise the upstream water level. A structure built across a stream or channel for the purpose of measuring flow.

technically a dam; the term is used to refer to the spillway of a waterfall or the opening on a pond skimmer.

definition – Is an opening or water channel. It is measured by the width. For instance you might say, “ I want the weir to be 2 feet wide and I want water 1 inch deep moving through it” The term is often used to refer to the spillway width of a waterfall or the opening on a pond skimmer.

a barrier or fence in water that diverts something: fish, water flow, erosive material.

A vertical structure in an open channel with a calibrated opening that measures water's rate of flow. (See also Flume.)

A spill over device used to measure or control water flows.

A barrier constructed to restrict the flow of water from a canal, ditch or other body of water. Water will flow over, but the weir prevents the flow of water below a certain level. Weirs can also be d [..]

A low dam or wall across a stream to raise the upstream water level. Termed fixed crest weir when uncontrolled.

An underwater structure that controls the flow of water. Weir type oil skimmers use a damlike underwater barrier that lets oil flow into the skimmer while holding back the water.
