TRL Report 515 : Vegetation for Slope Stability
Shallow slip failures on embankment and cutting slopes are more likely in certain geologies, particularly over-consolidated clays. The reinstatement of these shallow failures can be costly and the potential for slips may be reduced not only by the use of vegetation planted to provide reinforcement, through the plant root system, but also by a reduction in moisture content and pore water pressure. Report reviewing the potential for vegetation as a preventative measure in high-risk areas as well as investigating associated aspects such as the use of vegetation on reinforced steepened slopes in road widening and the use of live willow poles in reducing the risk of shallow failures.
