Objectives

At the end of this laboratory experiment, students are able to:
 Calculate the discharge rate of water on the weir
 Compare the rectangular weir, triangular or V-notch weir and trapezoidal weir’s discharge rate.
 Determine the importance of weir installation on water way and in engineering aspect.

Significance:

Weirs are commonly used to measure or regulate flow in rivers, streams, irrigation
canals, etc. Weirs are also built to raise the water level in a channel to divert the flow to
irrigation systems that are located at higher elevations. Engineers should consider the proper construction of weirs in rivers, dams or reservoir to control the flow rate of it during periods of high discharge (Hanania, et. al, 2020).
