Antarctic Circumpolar Current flows more rapidly in warm phases
ACC warm phases climate change
2021/8/4
Our planet's strongest ocean current, which circulates around Antarctica, plays a major role in determining the transport of heat, salt and nutrients in the ocean. An international research team led b...
Mass-flux subgrid-scale parameterization in analogy with multi-component flows: a formulation towards scale independence
Mass-flux subgrid-scale multicomponent flows a formulation towards scale independence
2014/12/10
A generalized mass-flux formulation is presented, which no longer takes a limit of vanishing fractional areas for subgrid-scale components. The presented formulation is applicable to a~situation in wh...
Estimating mass-wasting processes in active earth slides–earth flows with time-series of High-Resolution DEMs from photogrammetry and airborne LiDAR
mass-wasting processes active earth slides earth flows time-series High-Resolution DEMs
2009/12/16
This paper deals with the use of time-series of High-Resolution Digital Elevation Models (HR DEMs) obtained from photogrammetry and airborne LiDAR coupled with aerial photos, to analyse the magnitude ...
Terraces cover large areas along the flanks of many alpine and prealpine valleys. Soil slips and soil slips-debris flows are recurrent phenomena along terraced slopes. These landslides cause damages t...
A GIS-based numerical model for simulating the kinematics of mud and debris flows over complex terrain
GIS-based numerical model kinematics of mud debris flows complex terrain
2009/12/10
This article presents MassMov2D, a two-dimensional model of mud and debris flow dynamics over complex topography, based on a numerical integration of the depth-averaged motion equations using a shallo...
Simulating debris flows through a hexagonal cellular automata model: SCIDDICA S3–hex
debris flows a hexagonal cellular automata model
2009/12/10
Cellular Automata (CA) represent a formal frame for dynamical systems, which evolve on the base of local interactions. Some types of landslide, such as debris flows, match well this requirement. The l...
