The experiments for the erosion of tall and flexible vegetation by non-disturbed large scale samples were carried out in order to establish an evaluation method for the erosion resistence of the vegitation on river levees.
The mechanism of the erosion resistence was described by the results of the experiments. Then, the framework of the evaluation method was examined by the analysis of the relation between the condition of the vegitation, such as plant species, plant height and vegitation density; and the hydraulic condition, such as water depth and surface slope.
