Vegetation of embankment plays an important role in river management, such as contributing to erosion resistance of embankments. Therefore, in this research, in order to prevent serious damage caused by the erosion of the embankment, it is necessary to survey of the number of vegetation after the end of embankment vegetation construction, visual evaluation of 5-stages and root strength We conducted surveys and organized their respective relationships. As a result, a positive correlation was found between the 5-stage evaluation of coating condition and root strength. The actual condition of vegetation until the second year after the embankment construction finish was clarified, and valuable results were obtained for the construction and management of embankment vegetation.
