This paper is concerned with bed-load rate on movable beds ac companied by vegetation. Firstly, some flume experiments are carried out with two kinds of plant-models which are cylindrical and curved to downstream, and branched and inclined also to downstream. Secondly, a one-dimensional κ-e turbulent flow model is composed in order to estimate the efficient tractive force of bed-load. Model qualification is performed based on velocity data collected in the above experiments. Relation between… CONTINUE READING
