Abstract
Many engineering practices analysis of flow characteristic in compound channel becomes essential for adequate design. Several studies have been carried out since last three decades, where results of conventional methods are not well defined. It happens because of neglecting the concept of “Momentum transfer mechanism”, which occurs at interface of main channel and flood plain. Therefore, an effort is made to develop a method considering “Momentum transfer mechanism” for steady flow conditions in case of both symmetrical and unsymmetrical multi-stage compound channels, i.e., for generalized condition of compound channel. A computer program has been developed for this purpose. Observations of stage-discharge diagrams using different equivalent roughness formulae have been presented. Apparent shear stress, velocities, and discharges were compared with previous studies for symmetrical compound channel. Furthermore, stage-discharge curves are presented for a four stage compound channel.
