Avalanche Simulation
Avalanche flow simulation over the topography of Mt. St. Helens, WA, USA
(Digital Elevation Map data courtesy of USGS, Unit of Vancouver, WA),
based on a shallow flow model
with friction and complex topography (Bouchut and
Westdickenberg, Comm. in Math. Sci., 2, 359-389, 2004).
Computation performed by SHALTOP2D, a numerical model developed
in the framework of a collaboration between
DMA/ENS and IPGP.
