Abstract
Three-dimensional model for rockfalls Assumes point-like boulders Simulates trajectories from user-defined starting points Trajectories are a sequence of falling, bouncing, rolling states Boulders stop when kinetic energy is exhausted by friction Input: digital elevation model (here, 10 m national DEM, 300,000 km2) Ancillary data: terrain geological/lithological information => terrain parameters (friction coefficient, normal & tangential restitution)File in questo prodotto:
