Abstract: Based on the vectorial analysis of forces acting on non-cohesive sediment particle to be on arbitrarily vegetated riverbed, the basic equation of coarse particle movement is derived, a vectorial bed-load formula is founded under non-equilibrium condition. To verify above-mentioned formulas, some flume experiments are done by means of a straight channel with different planting length and density. The observed data on channel width adjustment are compared with calculating results of channel processes using above vectorial formula.
