The present paper deals with hydraulics in compound open channels with vegetation, the purpose of which is the application of the experimental results to planning and design of actual rivers. The experimental study was performed by measuring the resistance to flow in channel with artificial reeds and lateral velocity distribution at various design discharges. The laboratory tests indicate that the resistance coefficient is increased considerably (by 53%) even if the vegetation locates only at low banks. As an experimental technique, it was found that fine nylon-filament was the best to simulate flexible vegetation.
