The purpose of this study is to examine the hydraulic stability of the vegetation mat method on
high water revetment. Recently, the river is managed not only for the flood control also for the
environmental friendliness. For improving the environmental function of the river, the ecological river
restoration projects are being performed. To ensure the stability of flood control, instead of removal of
concrete revetment, the vegetation mat method has been widely used on the recovery soil. However, the
recovery soil method often failed to be stable against the flood, which has caused the economic loss. In
this study, the rate of soil loss is evaluated by the hydraulic experiments. Also, the velocity distribution
on high water revetment is analyzed by both the hydraulic and numerical experiments.
