    Summary
    Steady open channel flow with curved streamlines cannot be treated with a hydraulic approach unless an extended Boussinesq-type energy equation is considered to account for the non-hydrostatic pressure distribution. The paper reviews approximate modeling of these flows by the notable theory of Carlos Fawer. This discussion intends to add to Fawer's model by comparing it with the Dressler curved-flow equations, not quoted in the original paper. Based on a comparative analysis of the present comments Fawer's theory is demonstrated to be relevant as compared to other formulations, supporting its importance, as highlighted in the original paper
