Supercritical flow flumes for measuring sediment-laden flow
A general type of supercritical flow flume has been developed over many years of experience and testing in discharge measurements at the Walnut Gulch experimental watershed, Tombstone, Ariz. The design and experience with the original type flume, called the Walnut Gulch flume, is discussed and its features and application difficulties are described. Methods have been developed to analyze flows that exhibited lateral asymmetry in cross sectional profile, and porous dikes have been developed to considerably reduce asymmetry in the alluvial approach section to these flumes. Rating relations have ...
