Abstract
Unsatisfactory features of the equation that is recommended in HEC-18 (Richardson and Davis, 2001) for predicting pressure-flow scour are pointed out. These are found to stem from the basic model of the regression analysis performed by Arneson (1997), and an unfortunate transformation resulting in the final form of the equation. Alternative approaches are examined.
