Abstract

The presence of vegetation has a significant impact on the flow conditions in streams and rivers by changing the roughness, which has an important effect on flow velocity distribution. The article focuses on modelling and analysing the depth-averaged velocity distribution in a rectangular channel partially covered by submerged grassy vegetation. The possibility of using two selected models (CCHE2D flow model and Shiono and Knight model) has been evaluated using the measurement data from a laboratory experiment. The measurements and modelling have been carried out for different flow conditions. Applied models calibrated for low velocities were found to be extendable to the same vegetative condition during high velocities.
