Warning Model for Shallow Landslides Induced by Extreme Rainfall [PDF]

Water, 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.

A Landslide Numerical Factor Derived from CHIRPS for Shallow Rainfall Triggered Landslides in Colombia

Remote Sensing, 2022
Despite great advances in remote sensing technologies, accurate satellite information is sometimes challenged in tropical regions where dense vegetation prevents the instruments from retrieving reliable readings. In this work, we introduce a satellite-based landslide rainfall threshold for the country of Colombia by studying 4 years of rainfall ...

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

First report on the soil seed bank damage due to fire at the Rohingya refugee camps in Bangladesh

JSFA reports, EarlyView.
Abstract Background The composition, density, and damage of the soil seed bank were studied at Kutupalong Rohingya refugee camp (the world's largest refugee settlement), Ukhiya, Cox's Bazar, Bangladesh, after a major human‐induced fire on March 22, 2021, causing huge damage to human lives, settlements, and the ecosystem.

Influence mechanism of vegetation infiltration effect on shallow landslides of granite residual soil

Shuiwen dizhi gongcheng dizhi, 2023
The landslides induced by typhoons and rainstorms in Southern China are often shallow, fluidized and clustered. A large number of investigations have shown that vegetation infiltration has a significant impact on the formation of granite residual soil ...

Vegetation Improves Hydro‐Mechanical Soil Resilience on Humid Tropical Slopes: Field Evidence for Sustainable Land Management

Land Degradation &Development, EarlyView.
ABSTRACT Landslides represent a recurring hazard in humid tropical regions, primarily driven by intense rainfall that weakens slope materials and reduces shear resistance. Vegetation is widely promoted as a nature‐based solution to improve near‐surface soil conditions; however, systematic field‐based hydro‐mechanical evidence from humid tropical ...

Disposition Model for Permafrost Degradation in Mountainous Regions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Incorporating light pollution into projections of the future distribution of Aspisoma sticticum Gemminger, 1870 under climate change in South America

Insect Conservation and Diversity, EarlyView.
Climate‐only models predict severe habitat contractions by 2100, especially in the Amazon, Cerrado and Caatinga, while southern and coastal Atlantic Forest areas remain refugial. Including artificial light at night increased projected stability and apparent suitability gains, especially in central and eastern South America.
