Abstract

The use of plants against shallow landslides and erosion has received considerable attention over time as it is believed that vegetation provides mechanical and hydrological reinforcement to the soil. However, neither the soil-root mechanical reinforcement under different hydrological regimes, nor the hydrological effects of vegetation on soil reinforcement have been properly studied.

This paper explores how plants are able to provide mechanical and hydrological reinforcement to soil under different soil hydrological regimes. To do this, we first defined a novel, simple and reproducible laboratory protocol to investigate how changes in soil moisture affect the mechanical effects of vegetation on soil reinforcement. We then explored how plants modify the relevant soil properties and what implications this may have on soil reinforcement. We finally attempted to evaluate the suction stress functions for both fallow and vegetated soil, as a proxy to quantify the hydrological plant-derived soil reinforcement.
