Sharp-crested weirs cause a defined backwater and are often used to determine the discharge of an open channel. In this set, the rectangular weir with optional aeration demonstrates the fundamentals of flow over sharp-crested weirs, while the other three serve as measuring weirs with defined triangular, rectangular and trapezoidal openings. All four fit the EXPERIMENTAL FLUME FLOW CHANNEL APPARATUS at an identical weir height, using one holder for the measuring weir under study.
