Ways to prevent landslides

LESSON SUMMARY. Gravity moves earth materials from higher elevations to lower elevations. Landslides, avalanches, and mudflows are examples of dangerous erosion by gravity. Slump and creep move material slowly downslope. Plants, retaining walls, and good drainage are ways to help prevent landslides.

Landslides are the most widespread geological event; in fact, they are responsible for more than 18,000 deaths between 1999 and 2017. They also affected more than 4.8 million people worldwide during the same period of time. As technology advances, ways to prevent landslides are increasing in number and effectiveness. There are also various direct methods of preventing landslides; these include modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage. Such direct methods are ... 5. Which is/are the possible way/s to mitigate rainfall-induced landslide in a landslide prone area? a. Plant more trees, grasses, and other vegetation to prevent erosion and for compaction of soil. b. Do not build your house on or near steep slopes, mountain edges, drainages, or natural erosion valleys.Feb 7, 2020 · Topsoil, which lies closest to the surface of the land, contains essential nutrients for crops.

By preventing the soil from being washed away, the mesh helps to prevent landslides. Soil erosion is a serious problem especially in sloped areas where the slope is large and there are a lot of smaller rocks and particles. The soil can be carried away by rain or water runoff, leaving the slope unprotected and susceptible to landslides.

Trees prevent floods, landslides They help the groundwater supply recharge, prevent the transport of chemicals into streams and prevent flooding. The trees’ roots suck water deep from under the ground to as low as 200 feet. They hold the soil together so that erosion is prevented.Many things the authors predicted would be important, including the size or the intensity of landslide events, made little difference to the death toll for landslides below about 20 feet depth. Similarly, the distance between a building and the landslide slope, or an inhabitant’s age and gender, didn’t make a big difference to their survival.Landslide Hazards Program (LHP) The program's goal is to reduce long-term losses from landslides.
