What is the meaning of Weir?
1 : a fence or enclosure set in a waterway for taking fish. 2 : a dam in a stream or river to raise the water level or divert its flow. Weir.
Do we still use weirs?
In fact, many old weirs that are no longer needed are being replaced or completely removed to restore the river to its natural state. But as long as we need to control the flow of water in our constructed environment, weirs will continue to be an important tool for a hydraulic engineer.
What is the best shape for a weir?
Different shapes of weirs can pass flow more efficiently and thus have a higher discharge coefficient, but this has a practical limit. The most efficient shape for a weir is to match the curve that the water would take off of a sharp crest. This part of the flow is called the weir’s nappe, and the shape that matches it is called an ogee.
What is an ogee crested weir?
This part of the flow is called the weir’s nappe, and the shape that matches it is called an ogee. With ogee-crested weirs, we can get discharge coefficients as high as around 4, but that’s pretty much the limit.
