a weir

Definition of a weir in English English dictionary: were
weir: an adjustable dam placed across a river to regulate the flow of water downstream
weir: A discharge structure used for the controlled release of water volumes
weir: An enclosure set in a waterway for catching fish
weir: An enclosure set in a waterway for counting fish, or measuring water flow
weir: A small dam that causes water to back up behind it and flow over or through it Often has a notch used to control or regulate flows over it
weir: Also called skimmer weir - Part of a skimmer that adjust automatically to small changes in water level to assure a continuous flow of water to the skimmer The small floating "door" on the side of the skimmer that faces the water over which water flows on its way to the skimmer The weir also prevents debris from floating back into the pool after the pump shuts off
weir: a structure that extends across the width of a channel and is used to impound, measure, or in some way alter the flow of water through the channel
weir: a low dam built across a stream to raise its level or divert its flow a fence or wattle built across a stream to catch or retain fish
weir: a notch in the top of a photo processing tank for measuring flow
weir: {i} dam, sluice-gate, levee; fish-snaring net or fence
weir: A fence or enclosure set in a waterway to raise the water level or to gauge or divert its flow Return to top Notice To Users
weir: A low DAM or wall across a STREAM to raise the upstream WATER LEVEL Termed fixed crest weir when uncontrolled
weir: Weirs are concrete basins sited on streams that measure stream and stormflow by a water level recorder Scientists at Coweeta also take weekly samples for chemical analysis They can see the effects of any land disturbance, storm, insect infestation, etc Any water that is not absorbed by the vegetation or the soil ends up running through the weir The location for the lab was originally chosen in the Coweeta Valley basin because of it's unique sub-watersheds, high rainfall, and tight impermeable bedrock
weir: A barrier placed across a stream, river, or canal to catch or hold fish, or to raise or divert the water in order to regulate its flow
weir: a fence placed across a river to catch fish
weir: A low structure across a watercourse retaining only a small proportion of the mean annual flow
weir: A low dam or fence constructed across a stream or river to control water level or to direct water in another direction or into another facility
weir: 1 A wall or plate placed in an open channel to measure the flow of water 2 A wall or obstruction used to control flow from settling tanks and clarifiers to ensure a uniform flow rate and avoid short-circuiting (See: short-circuiting )
weir: Part of the skimmer that adjusts to changes in water level so skimmer is continuously supplied with water, prevents debris that has entered the skimmer from reentering the pool after the pump is off
weir: A man-made blockage across a stream allowing water to pass over
weir: an obstruction placed in a stream, diverting the water through a prepared aperture for measuring the rate of flow
weir: a low dam built across a stream to raise its level or divert its flow
weir: 1) A fence set in a waterway for catching fish; 2) A dam in a stream to raise the water level or divert its flow
weir: a fence or wattle built across a stream to catch or retain fish
weir: A long notch with a horizontal edge, as in the top of a vertical plate or plank, through which water flows, used in measuring the quantity of flowing water
weir: A weir is a wooden fence which is built across a stream in order to create a pool for catching fish. a low fence or wall that is built across a river or stream to control the flow of water, or to make a pool where people can catch fish
weir: 1) A wall or plate placed in an open channel to measure or regulate the flow of water 2) A wall or obstruction used to control flow from settling tanks and clarifiers to assure a uniform flow rate and avoid short-circuiting
weir: A weir is a low barrier which is built across a river in order to control or direct the flow of water
weir: A fence of stakes, brushwood, or the like, set in a stream, tideway, or inlet of the sea, for taking fish
weir: stone enclosure erected in a shallow waterway, used for trapping and spearing fish
weir: 1) A wall or plate placed in an open channel and used to measure the flow of water The depth of the flow over the weir can be used to calculate the flow rate, or a chart or conversion table may be used 2) A wall or obstruction used to control flow (from settling tanks and clarifiers) to assure uniform flow rate and avoid short-circuiting
weir: A dam in a river to stop and raise the water, for the purpose of conducting it to a mill, forming a fish pond, or the like
weir: A dam type of structure installed to provide additional head from a river supply to a farm, or for measurement of the flow of the river Measurement weirs are either flat crested or V shaped V notch weirs are often the option chosen as they give good accuracy at both low and high flows, whereas flat topped weirs can be inaccurate at low flows
weir: A wall across a river to control its flow, such as the ‘locks’ on the Murray They are dangerous, because the flow at the surface immediately downstream of the weir will be upstream objects (i e boats and people) can be trapped in the circulating flow Keep well away from weirs, both upstream and downstream
weir: An enclosure set in a waterway for taking fish
