### Defination / Uses

Broad Crested Weirs are a sturdy structure used to determine the channel's entire width. A broad crested weir is often a flat-topped item that obstructs the channel and spans across it. m Broad crested weirs are overflow structures on which the nappe is supported for a significant length in the flow direction.

Broad crested weirs are overflow structures on which the nappe is supported for a significant length in the flow direction. When compared to the flow thickness of water in canals and rivers, it is a flat-crested structure with a lengthy crest. The diffrance between broad crested weir and sharp crested weir is that, the sharp crested weir aids in the measurement of water discharge from minor rivers and canals, and it is positioned in the flow of water. The water flow discharge from large water bodies such as canals and rivers is measured by a broad crested weir. For quick calculation use our weetools.
