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 been developed by both experimental and theoretical means. The experience with the Walnut Gulch flumes has led to an improved design of supercritical flume, called the Santa Rita flume. The Santa Rita .flume design is presented in several sizes, along with a discussion of design requirements for stilling well intakes to minimize sediment inundation, record lag interpretation, and construction methods. 000157053 546__ $$aEnglish 000157053 650__ $$aResearch and Development/Tech Change/Emerging Technologies 000157053 650__ $$aResource/Energy Economics and Policy 000157053 6531_ $$aOpen channel 000157053 6531_ $$aflow 000157053 6531_ $$aflume 000157053 6531_ $$astilling well 000157053 6531_ $$asediment transport 000157053 6531_ $$ameasurement 000157053 6531_ $$asupercritical 000157053 6531_ $$aalluvial 000157053 6531_ $$asonar 000157053 6531_ $$apressure transducer 000157053 6531_ $$ainstrumentation 000157053 6531_ $$adesign 000157053 6531_ $$aintake 000157053 700__ $$aSmith, R.
