10.5: Landslide Types and Processes - Geosciences LibreTexts

21/01/2017· The term “landslide” describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these. The materials may move by falling, toppling, sliding, spreading, or flowing. Figure 1 shows a graphic illustration of a landslide, with the commonly accepted terminology describing its features.

Landslide Types and Processes - USGS

24/03/2014· The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time. For example, sedimentary rock shale becomes slate when heat and pressure are added. The more heat and pressure you add, the further the rock …

Understanding landslides - British Geological Survey

A landslide is a mass movement of material, such as rock, earth or debris, down a slope. They can happen suddenly or more slowly over long periods of time. If the force of gravity acting on a slope exceeds the resisting forces of a slope then the slope will fail and a landslide occurs. External factors, such as heavy rainfall leading to saturation of the ground, erosion of the base of a slope or changes to …

Geographical Processes - The Formation - Landslides

Geographical Processes in the formation of Landslides Landslides occur when the downward force of gravity acting on the slope is greater than the force holding the soil particles together. The downward force can occur in many different ways. The factors that contribute whether landslides will occur are the steepness of the slope, the shape of the slope and the properties of the materials in the slope.

Landslides - an overview | ScienceDirect Topics

A landslide is a movement of a mass of rock, debris, or earth down a slope ( Cruden, 1991). Several systems have been proposed in literature to classify landslides, but probably the most used system is that of Cruden and Varnes (1996) that emphasizes the type of movement and the type of affected material.

Landslide mitigation - Wikipedia

Landslide mitigation refers to several man-made activities on slopes with the goal of lessening the effect of landslides. Landslides can be triggered by many, sometimes concomitant causes. In addition to shallow erosion or reduction of shear strength caused by seasonal rainfall, landslides may be triggered by anthropic activities, such as adding excessive weight above the slope, digging at mid-slope or at the …

Activated by the landslides, geochemical processes on slopes, such as the capillary processes or washing out by groundwater, cause a redistribution of ions within the active layer and upper permafrost (Geertsema et al. 2009). Due to this, besides the C and N redistribution, soil active layer loose nutrients, which might in part accumulate beneath the permafrost table, then wash away and reach the drainage …

15/11/2018· The landslide probability is the probability that a hazard (landslide) will occur at a specific site. A landslide is the downward mass movement of slope-forming materials, such as soil, rock, artificial fills, or a combination of these, resulting from nature's pursuit of equilibrium ().A landslide can be classified depending on the type of soil (rock, debris, soil) and the type of movement ...

Monitoring Slope Movements (U.S. National Park Service)

19/01/2018· A hollow metal tube can be installed within a drilled hole, which can then be periodically measured to determine the variation of the original inclination of the tube. Ideally, the subsurface location of a landslide rupture can be detected with the inclinometer. Measurement of inclinometer systems can be connected to data loggers so that movement can be regularly monitored and recorded on ...

Landslide-Induced Wave Hazard in the village of …

The size of the expected landslide zone was determined based on available geological information and surrounding landslide observations. A 30,000 m³, 100 m high landslide was simulated with a mesh of 3.1 million cells. Uniform cells of 3 m sides, by 1 m high were used. Maximum sliding velocity reached 23 m/s at point of entry. The wave reached the dam with a height of 8 m and a velocity of 10 ...

Scrap - Wikipedia

Scrap metal originates both in business and residential environments. Typically a "scrapper" will advertise their services to conveniently remove scrap metal for people who don't need it. Scrap is often taken to a wrecking yard (also known as a scrapyard, junkyard, or breaker's yard), where it is processed for later melting into new products.
