Abstract It was claimed that the characteristics of free overfall with supercritical inflow conditions were not studied to date. That is incorrect and the Canadian Journal of Civil Engineering published a pertinent study about 10 years ago (Chanson and Toombes 1998). After a review of that study, it will be emphasised that the writers' results must be considered with caution. The supercritical flow at an abrupt drop is strongly three-dimensional and unsteady, and this aspect has direct implications for engineering designs.
