Prevent landslides by vegetation

The use of vetiver grass perpendicular to the flow direction will help reduce the speed of surface erosion agents such as water, wind, limit erosion, keep the soil washed away above the grass fence, stabilize the water regime. heat.

Explain more about the use of vegetation to prevent slipping - sliding , Associate Professor - Dr. Nguyen Ba Ke - former Director of Institute of Construction Science and Technology, Ministry of Construction - said: "The purpose of the way Legal measures to prevent landslides - landslides by vegetation are to control surface water (rain water), not to allow or limit the situation of surface water flowing into streams. face, control soil drift, stabilize hydrothermal mode, keep soil moisture ".

Vetiver grassland.

One of the most commonly used grasses is vetiver grass with a hard, flat, vertical stalk, ranging from 1.2 to 1.8 m high, growing in the form of seed growth into dust. This grass has a bunch of roots, deep into the ground, length from 1.5-2m, forming a core mesh system that links soil layers and soil particles. After 4-6 months of planting, vetiver will significantly improve the physical and chemical properties of the soil, keeping soil particles from being washed away.

The use of vetiver grass perpendicular to the flow direction will help reduce the speed of surface erosion agents such as water, wind, limit erosion, keep the soil washed away above the grass fence, stabilize the water regime. heat, moisturizing, enabling other types of plants to grow and cover the entire slope. Vetiver grass is applied to most soil types where other plants grow.
