What causes slumps to develop?
A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. Causes of slumping include earthquake shocks, thorough wetting, freezing and thawing, undercutting, and loading of a slope.
Where do slumps mostly occur?
Slump is common where clay-rich materials are exposed along a steep slope. Such oversteepend slopes naturally occur on the outside of meanders along the Red River. Slump is typically identified as the downward movement of a block of earth material along some curved surface of failure.
How can slumps be prevented?
Engineering solutions include barriers and retaining walls, drainage pipes, terracing the slope to reduce the steepness of the cuts, and immediate revegetation. Rockfalls can be controlled or eliminated by the use of rock bolts, cables, and screens and by cutting back slopes to lesser gradients.
What causes soil creep to occur?
Soil creep usually occurs during and after rain. The amount of creep caused by one rainfall has a positive correlation with the amount of rain and increase in soil moisture. Soil gradually concentrates directly below the knick point, and the slope becomes steeper and unstable.
What are the causes of rotational slide?
Rotational slides occur when the a landslide occurs in a curved manner concave to the sky. When this type of slide occurs, the upper surface of the slide tilts backward toward the original slope and the lower surface moves away from the slope.
Where do creeps occur?
creep, in geology, slow downslope movement of particles that occurs on every slope covered with loose, weathered material. Even soil covered with close-knit sod creeps downslope, as indicated by slow but persistent tilting of trees, poles, gravestones, and other objects set into the ground on hillsides.
What is slumps in geography?
slump, in geology, downward intermittent movement of rock debris, usually the consequence of removal of buttressing earth at the foot of a slope of unconsolidated material.
What are the slumps?
Slump is the measure of concrete consistency and fluidity. It shows the flow and overall workability of freshly mixed concrete. Simply put, the higher the slump, the wetter the mix. Four-inch (4”) slump is very common with normal weight concrete and is a good for pumping.
What are slumps in geography?
Can creep be prevented geology?
Cover exposed soil with a variety of plants — trees, shrubs, perennials and annuals — to create a barrier that stops soil movement from both wind and water. The plants’ roots will hold the soil in place, as well. Lay mulch or stone between plants to provide additional coverage of exposed dirt.
