Webmaster's Ph.D. Thesis

[Pyroclastic flows and surges generated by column collapse. Time and location unknown.]

As requested by many visitors, I made here available my Ph.D. and other publications around it. I would really love to hear from you. If you have the least comments, inputs, question just feel free to email me at sebastien@granular.org. Thanks.

The official reference of this Ph.D. is:
Dartevelle, S., Numerical and granulometric approaches to geophysical granular flows, Ph.D. thesis, Michigan Technological University, Department of Geological and Mining Engineering, Houghton, Michigan, July 2003.
