A class of portable, long-throated flumes, the RBC is a relatively recent (1984) flume developed to measure flows in earthen channels and furrows by researchers at the U.S. Department of Agriculture and the International Institute for Land Reclamation.
Named for its developers, Messer's Replogle, Bos, and Clemmens, the RBC flume is a series of 5 different flumes that are intended to be highly portable, easy to make, and extremely accurate.
The RBC flume has a constant, truncated V-shape allowing it to conform to the normal shape of furrows and irrigation channels. The throat of the flume consists of a sloped ramp (similar to a Palmer-Bowlus flume).
As a long-throated flume, the RBC flume can be designed and calibrated through the use of computer analysis. This analysis eliminates the need to laboratory or field rate new or nonstandard RBC flumes sizes with excellent accuracy.
As with other long-throated flumes, the RBC flume has a high modular limit (submergence transition) of 90%.
