Question

what are the method that can be used to prevent landslides

Answer 1

For temporary landslide prevention, sandbags can be used to divert water from uncontrolled spilling just as retaining walls or diverted pathways do. Another method is to protect unstable areas with plastic sheeting, tarps or even burlap, especially in areas without vegetation because of recent fires.

To achieve this result, some actions are required:

1.Covering the land with impermeable membranes in order to prevent water infiltration in the landslide.
2.Directing surface water sources away from the landslides.
3.Draining ground water streams away from the landslides.
4.Minimizing irrigation on the surface of the soil.
