WebChezy katsayısı 1768'de tanıtılırken, Gauckler-Manning katsayısı ilk olarak 1865'te, 1920-1930'lardaki klasik boru akış direnci deneylerinden çok önce geliştirilmiştir. Tarihsel olarak hem Chezy hem de Gauckler-Manning katsayılarının sabit olması ve yalnızca pürüzlülük fonksiyonlarının olması beklenmekteydi. The Chézy formula is an semi-empirical resistance equation which estimates mean flow velocity in open channel conduits. The relationship was realized and developed in 1768 by French physicist and engineer Antoine de Chézy (1718–1798) while designing Paris's water canal system. Chézy discovered a similarity parameter that could be used for estimating flow characteristics in one channel based on the measurements of another. The Chézy formula relates the flow of water th… WebManning’s formula shall not be applied in situations where Reynolds number effect is predominant.
