Abstract
The results of experiments discussed in this paper show that some characteristics of gravity waves in finite-depth water can be used in the case of steady flows with a pronounced nonuniformity in open channels. In particular, in addition to the classical critical velocity and depth, the higher (second) critical velocity and (second) critical depth can be used.
