Abstract
Conventionally, the effectiveness of vegetation revetments is determined by experience, observation and investigation at the river site, rather than quantitatively in a hydraulic laboratory. But as more river improvement projects seeking to make better use of the natural environ ment are pursued, it is necessary that a more scientifically based understanding be achieved of the ability of vegetation to resist erosion, and the effects of vegetation on the hydrological regime and on suspended sediment.
In this study, bank erosion experiments were couducted using a large-scale experimental water channel with sodded slopes, in a study of the erosion-controlling effects of vegetation, and of the accumulation of suspended sediment, which adversely affects the growth of vegetation.
