摘要：

The performances of four of the most commonly used methods for discharge calculation in compound channels of varying roughness, were assessed by comparison with laboratory data. The four methods are based on splitting the section into main channel and floodplain subdivisions using either horizontal or vertical interfaces. The accuracy of the four methods in calculating overall section discharge generally increases at greater floodplain depth and with smoother floodplains. However, the distribution of flow within the section is generally poorly modelled, which leads to very erroneous values for momentum and kinetic energy flux. Copyright © 1985 ASCE.
