The broad crested weir at the Thorp grist mill in Thorp, Washington, US Commonly, weirs are used to prevent flooding , measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures.
The Weir formula is a formula used in indirect calorimetry, relating metabolic rate to oxygen consumption and carbon dioxide production. According to original source, it says: [ 1 ] Metabolic rate (kcal per day) = 1.440 (3.9 VO 2 + 1.1 VCO 2 )
The hydrology of the Braden River was altered in 1936 when the city of Bradenton created Ward Lake, a reservoir with an 838-foot (255 m) broad-crested weir 6 miles (9.7 km) upstream from the mouth. In 1985 the reservoir was expanded and supplies an annual average of 5.7 million US gallons (22,000 m 3 ) of water per day.
In hydraulic engineering, a nappe is a sheet or curtain of water that flows over a weir or dam. The upper and lower water surface have well-defined characteristics that are created by the crest of a dam or weir. [1] Both structures have different features that characterize how a nappe might flow through or over impervious concrete structures. [2]
Hydraulic jump in a rectangular channel, also known as classical jump, is a natural phenomenon that occurs whenever flow changes from supercritical to subcritical flow. In this transition, the water surface rises abruptly, surface rollers are formed, intense mixing occurs, air is entrained, and often a large amount of energy is dissipated.

H = depth of flow over the crest (or floor) of the inlet (ft) H e = specific energy head in reference to the crest of the inlet, or the head over the crest of the inlet (ft) v a = mean velocity of approach at which the depth H is measured (ft/s) g = 32.16 ft/s 2
