The Vetiver System can effectively and at low cost mitigate most of these problems. This is because vetiver grass roots have a high tensile strength – average 75 MPa that can increase shear strength of soil by a factor of 40, and when planted on slopes vetiver will reduce slope hydraulic pore pressures through the removal (transpiration) of ...

The handbook: The Vetiver System for Slope Stabilization describes in detail VS applications. It has been written primarily for engineers and contains case studies and many color images of VS applications.

to vetiver grass’ extraordinary characteristics, VS also has important application as a bioengineering technique for steep slope stabilization, wastewater disposal, phyto-remediation of contaminated land and water, and other environmental protection purposes. What does the Vetiver System do and how does it work?

2020年2月1日 · Vetiver grass (Vetiveria zizanioides) is easily available in Bangladesh and widely known for its long fibrous roots which significantly increases shear strength of soil. This paper aims to...

2023年6月26日 · planting vetiver can enhance slope stability. Analysis of soil shear strength with vetiver grass reinforcement was also carried out by comparing the soil shear

2021年6月29日 · Bio-engineering technology, using vegetation, offers an effective solution to slope protection, as the roots of the vegetation reinforce the earthen slopes and enhance their stability. This study attempts to evaluate the improved shear strength parameters of rooted soil and to determine the stability of vegetated slopes.

2022年3月8日 · Compared to sand/silt, vetiver performs better in sandy silt in reducing chances of shallow slope failure at the same geometry of natural slope. This study recommends vetiver as a sustainable and cost-effective approach for restoration of hill slopes along with reducing the risk of shallow slope failures and eventually landslides.

2023年10月24日 · Multiple field studies demonstrating vetiver's ability to significantly improve slope stability and reduce erosion rates under diverse conditions are reviewed. Overall, findings indicate that vetiver grass is highly efficient for stabilizing steep slopes up to 75% incline and reducing erosion by more than 90% compared to bare slopes.

2023年2月1日 · Root morphology and effects on soil reinforcement and slope stability of young vetiver (Vetiveria zizanioides) plants grown in semi-arid climate

2024年2月29日 · This research records a basic infinite slope stability problem to demonstrate the beneficial effect of vetiver grass root reinforcement in preventing shallow slides. The root diameter and tensile strength of vetiver grass grown in local soil from Guam varied between 0.11–2.22 mm and 14.4–1259 MPa (N/mm 2 ), respectively.
