Deep-seated and shallow-rapid landslides: know the difference
Nov 17, 2017 · Shallow-rapid landslides are debris-flow slides that occur within the forest rooting zone, generally less than 10 feet deep. They are typically initiated by intense rainfall and/or rapid snowmelt. Sudden saturation of the ground loosens the soil and triggers the slide.
Controls on the size distributions of shallow landslides - PNAS
Feb 26, 2021 · Shallow landslides are destructive and widespread natural hazards, but what controls their size distribution is poorly understood. We present a generalized theory to explain landslide size distribution at specific locations by combining a mechanistic slope stability model with a spatial-statistical description of the variability in hillslope ...
Landslide - Wikipedia
A landslide in which the sliding surface is located within the soil mantle or weathered bedrock (typically to a depth from few decimeters to some meters) is called a shallow landslide. Debris slides and debris flows are usually shallow.
Landslide Basics | U.S. Geological Survey - USGS.gov
Landslides are the downslope movement of earth materials (rock, debris, and soil) at rates that range from inches per year to tens of miles per hour. Some landslides can move faster than a person can run. Landslides can happen with no notice or can take place over a period of days, weeks, or longer.
Shallow landslides and vegetation at the catchment scale: A …
Dec 1, 2021 · Shallow, rainfall-triggered landslides are an important catchment process that affect the rate and calibre of sediment within river networks and create a significant hazard, particularly when shallow landslides transform into rapidly moving debris flows.
Deep learning forecast of rainfall-induced shallow landslides
Apr 28, 2023 · The ability to forecast accurately the possible occurrence of populations of rainfall-induced shallow landslides over large and very large areas without detailed information on the terrain...
Full article: Detection and forecasting of shallow landslides: …
Feb 23, 2022 · Shallow landslides occur where material fails in the upper layers of a soil profile, usually up to approximately 2 m depth. These landslides usually have little precursory warning and may fail rapidly (e.g., debris flow; Persichillo et al. 2016) or slowly (e.g., creep deformation; Hungr et al. 2014).
Deforestation Effects on Rainfall‐Induced Shallow Landslides: …
Oct 22, 2019 · Key Points. We quantify potential effects of deforestation on enhanced landslide activity on steep slopes. Deforestation effects are limited to a time window before forest regrowth reinforces the soil. STEP-TRAMM model captures salient features of deforestation practices and climate effects on landslides.
What is a landslide and what causes one? | U.S. Geological Survey
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows.
What Controls Shallow Landslide Size Across Landscapes?
Shallow landslides also play an important role in landscape evolution, dominating erosion in steeper landscape, unleashing debris flows that carve valley networks, and delivering sediment to rivers.
