An obstruction that allows the liquid to flow over it is called a weir.

Crest is a horizontal top edge of weir on which the liquid flows.

Broad crested weir: A broad crested weir is a rectangular block of width (or length) , w and height, p and w>p. As its name implies that this type of weir has a broad (large width) crest. In broad crested weir the width of the crest of the weir is more than half the height of water above the weir crest.
