Abstract
The direct step method is proposed to replace the computations by trial and error used in the standard step method for tracing water-surface profiles in natural channels. It is a semigraphical method applying Bernoulli’s theorem and includes the effect of velocity-head changes. The effect of eddy losses, bridge-pier losses, and overbank flow can also be included when necessary. The proposed method, which is conveniently applicable in general, has been found by the author to be especially advantageous when several water-surface profiles must be determined in the same channel.
