Julien Chauchat

Je suis Maître de Conférences à l’ENSE3 (INPG) depuis 2009 où j’enseigne l’hydraulique à surface libre et les méthodes numériques associées. Mes recherches portent essentiellement sur la modélisation du transport sédimentaire par des approches diphasiques et sur la modélisation des écoulements granulaires denses.
