What is a notch?

A Notch is a device used for measuring the rate of flow of a liquid through a small channel or a tank. It may be defined as an opening in the side of a tank or vessel such as liquid surface in the tank is below the level of opening.

What is a trapezoidal notch or weir?

A trapezoidal notch is a combination of a rectangular notch and two triangular notches. It is, thus obvious that the discharge over such a notch will be the sum of the discharge over the rectangular and triangular notches.
