There is an increasing need for quantitative rockfall hazard and risk assessment that requires a precise definition of the terms concepts used this particular type landslide. This paper suggests using appear to be most logic explicit as possible describes methods derive some main hazards descriptors. The presented concern process (failure, propagation, fragmentation, modelling) descriptors, dis...

[1] The 166,000 km fan-shaped deposit at Arsia Mons contains three characteristic facies (ridged, knobby, and smooth), which are interpreted as the depositional remains of a cold-based glacier that was present on the west–northwestern flanks in the Late Amazonian period of Mars history. Here, we consider several high-elevation graben on the western flank of Arsia Mons that are interpreted as th...

The transport infrastructure of a country facilitates the development and growth its economy improves quality life inhabitants. Increasing resilience to different types risks improve performance is becoming more important. In current context climate change, natural hazards are severe frequent. this article, we focus on rockfall as hazard for roads that occurs in small areas vicinity or cut slop...

Rockfalls pose a substantial threat to ground transportation, due their rapidity, destructive potential and high probability of occurrence on steep topographies, often found along roads railway routes. Approaches for the assessment rockfall susceptibility range from purely phenomenological methods statistical methods, suitable modeling large areas, deterministic ones, usually easier use in loca...

O objetivo desse trabalho é propor um modelo de predição da probabilidade queda blocos em taludes rochosos utilizando o método K-Nearest Neighbors (KNN). Foi utilizado banco dados composto por 220 rochosos, cujas variáveis estão relacionadas à presença água, características do maciço rochoso, descalçamento blocos, entre outras. Para cada talude dados, a (alta, média ou baixa) conhecida e foi de...
