Abstract: Monflo is a two-dimensional numerical model that was developed to calculate the flow characteristics of channels with compound cross sections. That is, it includes the effect of momentum transfer between the main channel and the flood plains. The model was adapted to run both with and without the inclusion of momentum transfer. A series of numerical tests was then run to compare the water level and flow distribution in a compound channel predicted with both versions of the model. It was found that the effect of momentum transfer on the water level was minimal. The impact on the flow distribution varied depending on the cross-sectional shape and the surface roughness.
