The University of Calgary, the University of La Rochelle and INRAE are pleased to invite applications for a PhD position (3 years) to model the mechanical behavior of granular materials subjected to cyclic hydraulic loading and to analyze the induced instabilities. This PhD project is part of the StabDigue project supported by the French Region Nouvelle Aquitaine on the analysis of both the stability and durability of dikes and retaining structures along the coastline. The PhD candidate will benefit from both a French-Canadian double PhD degree and the International Research Network Multi-Physics and Multi-scale Couplings in Geo-environmental Mechanics (GDRI CNRS GeoMech).
