Earthflows
WebJul 25, 2014 · Persistent Scatterer Interferometry (PSI) has been widely used for landslide studies in recent years. This paper investigated the spatial patterns of PSI point targets and landslide occurrences in the Arno River basin in Central Italy. The main purpose is to analyze whether spatial patterns of Persistent Scatterers (PS) can be recognized as … WebHowever, earthflows never leave such scars. Debris flows generally occur within semiarid areas and tend to be restricted to channels, whereas earthflows most often occur on hillsides in humid areas. Debris flows are composed entirely of very large rocks and boulders, whereas earthflows are composed of very small sediments.

WebMay 18, 2015 · In this study, the geophysical properties of the landslide-prone catchment of the Gaoping River in Taiwan were investigated using zones based on landslide history in conjunction with landslide analysis using a deterministic approach based on the TRIGRS (Transient Rainfall Infiltration and Grid-based Regional Slope-Stability) model. Typhoon … WebJun 24, 2016 · The larger earthflows tend to concentrate in natural swales (Fig. 2).The smaller earthflows often occur on the flanks of natural swales (Fig. 2, Fig. 3).Earthflows commonly begin as small rotational slumps, failing along log-spiral shaped rupture surfaces (Rendulic, 1935, Terzaghi, 1950).When these materials begin to translate downslope, …
An earthflow (earth flow) is a downslope viscous flow of fine-grained materials that have been saturated with water and moves under the pull of gravity. It is an intermediate type of mass wasting that is between downhill creep and mudflow. The types of materials that are susceptible to earthflows are clay, fine … See more Earthflows are just one type of mass movement that can occur on a hill slope. It has been recognized as its own type of movement since the early 20th century. Earthflows are one of the most fluid types of mass movements. … See more Earthflows vary in velocity of flow depending partly on the consistency of the flow for the speed of the entire movement, usually meaning how much water is in the material of the hill slope before the slope fails. Though water is often the key factor in slope failure, … See more The areas most at risk for earthflows are: • Slopes that have been undercut or loaded with more sediment for human construction See more Earthflows can have sudden impacts on the amount of sediment that is deposited into a river system, which can have effects on the life in and around the river itself. They can also cause damage to roads and constructions built near the slope.
