18 de may. de 2018 · Approfondimenti. Un debris flow, ovvero una colata di detriti, è un miscuglio di acqua e sedimenti che si muove per effetto della gravità. Un debris flow è un fenomeno molto pericoloso a causa sia della estrema velocità con cui può percorrere grandi distanze, sia per la frequente assenza di chiari segni premonitori.
1 de ene. de 2016 · Debris flow is an extremely rapid, flow-like mass movement, traveling in a steep, established channel and involving a saturated, unsorted mixture of granular soils, organics, and other debris (Hungr et al., 2001). Most steep natural slopes are mantled by varying thickness of colluvial soils, disturbed by surficial phenomena known collectively as soil creep, as well as small-scale landslides.
Colata detritica. La colata detritica (in inglese debris flow) [1] è un tipo di frana che consiste nel movimento verso valle, lungo un versante o nel greto di un torrente, di materiale detritico anche di notevoli dimensioni, solitamente accompagnato da una notevole quantità d'acqua, anche se sono possibili colate anche in materiale asciutto.

1 de sept. de 2022 · The purpose of this paper is therefore to present a broad and critical overview of the mathematical models and solution methods for representing debris-flow propagation, addressing the latest contributions. Guidelines for model classification and selection are supplied, simplifying the task of including new models.
The debris flow laboratory at the WSL offers the possibility to investigate debris flows at a small scale. This allows scientists to study, for example, flow behavior for various natural materials, investigate debris flow impact, explore the erosion process, and test instruments before deployment in the field.
2 de abr. de 2022 · Debris flow is a disaster that frequently occurs in mountainous regions worldwide due to climate change and human activities and can lead to serious economic losses and casualties. Hence, it is a societal priority to understand debris flow and to develop effective control measures. This Special Issue aimed to contribute to the knowledge and ...
