The important role of vetiver grass roots in preventing water erosion and mass movement has been well recognized, though the detailed influence of the grass roots on soil has not been addressed.
Through planting vetiver grass at the Kadoorie Farm in Hong Kong and leaving it to grow without artificial maintenance, the paper studies the influence of vetiver grass roots on soil properties and slope stability.
Under the natural conditions of Hong Kong, growth of the vetiver grass roots can reach 1.1 m depth after one and a half year from planting.
The percentage of grain size which is less than 0.075 mm in rooted soil is more than that of the nonrooted soil.
Vetiver grass roots can reduce soil erosion by locking the finer grain.
The rooted soil of high finer grain content has a relatively small permeability.
As a result, the increase in water content is therefore smaller than that of nonrooted soil in the same rainfall conditions.
Shear box test reveals that the vetiver grass roots significantly increased the peak cohesion of the soil from 9.3 kPa to 18.9 kPa.
The combined effects of grass roots on hydrological responses and shearing strength significantly stabilize the slope in local rainfall condition.
