The wide flow ranges of H flumes make them ideal candidates for measuring edge-of-field or catchment flows. Likewise, Parshall flumes work well when measuring creeks, streams, rivers, and other watershed contributors. However, when flumes are used to measure flow in channels, catchments, or fields that are wider than the flume itself, flow must first be channeled into the flume or the approach section before it can be measured.
Over the years, our customers have been innovative in their use of different materials for flow collection / diversion into their flumes. We’ve collected photos of those installations, and others, to give you a feel for how this can be inexpensively accomplished in the field. Certainly not every installation will lend itself well to every material, but given the range of materials shown below, we are confident that at least one will work for you.
In addition to the materials shown in these examples, Openchannelflow can also offer fiberglass wing walls – either attached to the flume or shipped loose for field attachment.
