Embankment slope vegetation is important for flood control such as contributing to the erosion resistance of the levee against running water. With regard to Noshiba etc. of the vegetation of the embankment in Honshu, the relationship of vegetation covering condition, amount of roots, root system strength etc. and endurance time to erosion is shown. On the other hand, there has been no quantitative measurement or evaluation of embankment slope vegetation in Hokkaido. Therefore, we investigated the vegetation condition and the strength of the root system after embankment work, and analyzed the factors that affect the strength of the root system. As a result, it became clear that it is necessary to measure soil hardness in addition to root system strength in order to estimate the amount of roots..
