Review of Natural Hazard
The following is a list of natural events and relative existing models, procedures, or works. Please feed the list with other phenomena and resources.
Rockfall
- r.rockcone (soon in GRASS-Addons)
Rockcone implement a quick and low-cost determination of areas endangered by rockfalls following an heuristic approach: a block tarting from a source will travel down the slope and stop at the intersection point of the topography with a so called energy line drawn from the source point and making an angle φ with horizontal.
- r.sass3D (in development by the IST-SUPSI)
Sass3d is 3D rock fall model accounting for flying routine (air trajectory), rebound routine (energy loss) & rolling routine (equivalent sliding approach).
Avalanche
missing, existing slope instability zonation applications (Raghavan et al. 2004)
Debris Flow
- r.debris paper
- r.dfw
Is an empirical model to estimate areas involved by the diffusion of the debris. It uses a Monte Carlo approach based on wolkers. The outputs are raster estimates of velocity, sedimentation height, and number of random walk. The Perla velocity model is applied.
