WebJan 19, 2010 · Critical flows may occur at more than one depth in channels having compound cross-sections (cross-sections with flood plains). The possibility of multiple critical depths affects the water-surface-profile calculations. Presently available algorithms determine only one of the critical depths which may lead to large errors. In this paper ... Webdischarge in compound channels is to divide the cross section into subsections by drawing vertical lines that start from the junction of the main channel and the floodplain as shown in Fig. 1. In this study, the velocities in the main channel and in the floodplains calculated by this division method are referred to as Vmc-VIM and
