AbstractThe paper analyzes the hydraulic calculation of channels with composed cross section having horizontal benches. Influences ofthe computation models on results of flows key are shown. There single cross section flow and parallel flows, by dividing thecross section, are considered.The nearest key of flows to the actually one corresponds to results of the model of dividing the composed cross section intosimply by horizontal, defined the banquet elevation....
