Funding from the Swiss National Science Foundation is available for a
PhD student to begin 1st May 2007 for a project entitled “Application of
Cellular Automata and Lattice Boltzmann methods for the study of tephra
transport and deposition”. The project will be supervised by Prof.
Costanza Bonadonna (Section des Sciences de la Terre) and Prof. Bastien
Chopard (CUI) of the University of Geneva and will be based at the
Section des Sciences de la Terre, University of Geneva, Switzerland
(http://www.unige.ch/sciences/terre/).
With this interdisciplinary project we are planning to use a combination
of multiparticle cellular automata (CA) and lattice Boltzmann (LB)
models to describe tephra dispersal and to investigate crucial tephra
deposit features, such as cone-like structures in proximal areas of
basaltic deposits, medial-to-distal sheet-like deposits, erosion
processes during sedimentation and toppling due to slope instabilities.
Results from this project will have important implications for the
assessments of tephra hazard in active volcanic areas. The project will
also involve field work in Ecuador and Chile (Cotopaxi and Villarrica
volcanoes) to collect dedicated data for the validation of the model.
Applicants must hold a diploma/master degree, or an equivalent level of
education, in Geology, Physics, Geophysics, or Computer Sciences (with a
taste for natural phenomena). A background in numerical methods and
programming is advantageous.
Interested applicants are encouraged to apply as soon as possible.
Please email a CV, a list of 2 referees, description of motivation and
experience relevant to the research project to Costanza Bonadonna, at
