Yes / In this paper, an improved Shiono-Knight model (SKM) has been proposed to calculate the
rectangular compound open channel flows by considering a Multi-Zonal (MZ) approach in
modelling turbulence and secondary flows across lateral flow direction. This is an effort to
represent natural flows with compound shape more closely. The proposed model improves the
estimation of secondary flow by original SKM model to increase the accuracy of depthaveraged
velocity profile solution formed within the transitional region between different
sections (i.e. between main-channel and floodplain) of compound channel. This proposed MZ
model works by sectioning intermediate zones between floodplain and main-channel for
running computation in order to improve the modelling accuracy. The modelling results have
been validated using the experimental data by national UK Flood Channel Facility (FCF). It
has been proven to work reasonably well to model secondary flows within the investigated
compound channel flow cases and hence produce better representation to their flow lateral
velocity profile.
