What are weirs used for

What Are Weirs Used For. Good accuracy when properly sized installed. A weir is a small dam built across a river to control the upstream water level. The substance is now being used to test drugs before approval by the FDA as well as to make sure that devices such as pacemakers are sterile. Alternatively fish weirs can be used to channel fish to a particular location such as to a fish ladder.

Sharp-crested weirs are useful only as a means of meas- uring flowing water. Compound weirs for dual flow range measurement. In contrast weirs not sharp crested are commonly incorporated into hydraulic structures as control or regulation devices with measurement of flow as their secondary function. A weir is generally used to regulate flow of water at a large scale like in rivers or canals.

But broad-crested triangular and contracted weirs are also favoured in certain circumstances. Rectangular weirs are used to extract water in order to emulate the effect. Unlike large dams which create reservoirs the goal of building a weir across a river isnt to create storage but only to gain some control over the water level.
