Luckily, the Parshall flume is the exception.
calculation flume flow Round bottom
These flumes are simpler to construct, can be more easily fit into an existing channel, and can trap less sediment than a Parshall flume. Palmer-Bowlus flumes were originally designed to measure piped flows. However, our software scales the y-axis based on the maximum value on the curve. All of the heads in the range entered for the graph result in parameters such as C d , C s , or C u that are invalid, so no flow rates could be computed.
