Abstract
The authors of the original paper have proposed new explicit equations for the head loss and normal depth for the wide rectangular and triangular open channel sections using the Colebrook white equation and Lagrange’s inversion theorem.
The ASCE Task Force on friction factors in open channels (1963) expressed its belief in the utility of using the Darcy-Weisbach formulation for resistance to flow in open channels for other than fully rough flow, however, these recommendations have almost been ignored, and the Manning-Strickler formulation continues to dominate, maybe because the most pipes and channels flow under turbulent conditions (Boukhari et al, 2021), (Zeghadnia et al, 2007, 2014, 2014a, 2017).
