Abstract
1 January 2009 ISSN 1816-7950 = Water SA (on-line) 14 Water Project. 0. In this assessment it was recognised that the DWAF equations were designed to cover a wide range of upstream pool depths and describe these flow conditions better than alternative formulae. Rating of sharp-crested (thin-plate) weirs for non-modular flow conditions Thin-plate weirs are usually designed to operate only under modular flow conditions. In South Africa, sharp-crested weirs are widely used to gauge flow in natural streams. It happens quite often that downstream water levels are higher than the crest elevations of these weirs.
