Landslides and Water: Slope saturation by water is a primary cause of landslides. Soil erosion is a major factor for desertification. 3⃣Cloudbursts. oversteepening of slopes, removal of support at base of the slope, weak slope materials, adding a load at the top of the slope, adding water or rain, reducing vegetation. In some cases, USGS scientists respond to landslides... Landslides can and do occur in every state and territory of the U.S.; however, the type, severity, and frequency of landslide activity varies from place to place, depending on the terrain, geology, and climate. Water availability, quantity, and quality can be affected by landslides. Landslides occur when gravitational and other types of shear stresses within a slope exceed the shear strength (resistance to shearing) of the materials that form the slope. Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors. A landslide is any geological process in which gravity causes rock,soil,artificial fill or a combination of the three to move down a slope. Mali yan New questions in Science. Desertification.
