摘要:
The equations of continuity, momentum and energy are derived, incorporating depth-dependent correction factors for velocity distributions over compound cross sections. It is shown that the friction slope and the energy slope are equivalent in steady uniform flow but not in unsteady flow. The difference between the two forms is explained and reasons are given for the preferential use of the momentum equation. Comparisons of backwater profiles are presented.
