Abstract

The classic sidewall correction procedure, Vanoni and Brooks' method, originates from Einstein-Johnson's work. However, Johnson's contribution is almost unseen in recent literature because his friction equation for the sidewall flow is difficult to solve. This note then revisits Einstein-Johnson's sidewall correction procedure and solves Johnson's friction equation explicitly and exactly. Besides, it extends Einstein-Johnson's procedure to transitional-, and rough-sidewall turbulent flows. The presented exact procedure facilitates Einstein-Johnson's sidewall correction for applications in flume experiments and sediment transport analysis in narrow canals, streams, and rivers.
