Mass Gravity Flows Modelling

2002
In the last decade, offshore pipeline engineering extended its action field to very deep waters and continental slopes. This implies the necessity to deal with continental slopes instability and mass gravity flows. Even if a standard classification of mass gravity flows does not exist in literature, they can be divided in two main different classes ...
