Paper reviews streamlined broad-crested weir and determines limitations on its use as structure of flow measurement; number of theoretical methods are put forward to explain characteristics of flow and are verified by analysis of experimental data; coefficient of discharge is derived from application of critical-depth theory allowing for development of boundary layer on crest; modular limit is determined by treating it as special case of hydraulic jump; study of water surface profile over weir leads to recommendations for length of crest, radius of nose and position of upstream level gaging position which give most economic design.
