Theoretical and experimental study of use of free overfall as flow meter which needs no calibration; although flow at overfall is not parallel, crest section is that of true minimum energy and hence is actual control section; furthermore, crest depth is constant percentage of computed critical depth for parallel flow; pressure distribution in region of crest; depth of flow at crest; effects of breadth of weir. (See also - n 10 discussion Oct p 690)
