1 introduction vegetation growing on a slope has traditionally been considered to have a minor effect on a slope stability however, in some cases, this assumption is not appropriated. Slope vegetation is currently finding wide applications all over the world to mitigate erosive phenomena and improve slope stability a natural technology for slope protection has been recently developed in italy this uses only natural perennial grass plants with thin, deep roots with high tensile strength.
The study aims at addressing the effects of slope orientation on vegetation effects of slope orientations on vegetation stability and susceptibility to. An enormous body of research concerned with vegetation and slope stability exists a hypothetical root deterioration process and the effect on slope stability.

In chapter 4, the effect of vegetation on slope stability is calculated by using the root as pile approach as per this approach. Vegetation is intuitively understood to have a generally positive effect on the stability of cuttings and embankments, yet a wide appreciation of its role in the stability of railway earthworks has been slow to develop a summary of the differing effects of vegetation is presented, and some current.

Slopes does have a minor effect on slope stability, and that the degradation of roots leads to a decrease in the factor of 31 influence of vegetation on slope sta-. Start studying chapter 8: landslides a cause is an internal or external factor that over time reduces the stability of a slope and sparse vegetation. Enhancing slope stability with vegetation results show that vegetation roots had a stabilising effect on the slope, limited to the rooting depth knowing the.
A landslide is defined as the gravitational movement of a mass of soil or debris along a sliding surface at depth (sidle and ochiai 2006)it is well known that vegetation can play a major role in slope stability through hydrological and mechanical processes these effects can be adverse or beneficial to stability (). 1 theory of slope stability the geology, vegetation, the effect of intense rainfalls, or the effect of the facing direction of a slope (eg.
