Natural Hazards

Natural Hazard Models

The following is a list of natural events and exisiting models, procedures, or works in the relative field. Please feed the list with other phenomena and resources.

Rockfall

• r.rockcone (soon in GRASS-Addon)

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

• r.dfw (porting to GRASS)

Flood

r.sim.water, HydroFOSS, r.topkapi, r.water.fea, r.hydro.CASC2D

Landslide

missing, existing slope instability zonation (Ciolli and Zatelli, 2002)

Erosion
