Be analysis of bottom sediments in dynamic fluid-structure interaction problems

Sediment materials play an important role on the dynamic response of large structures where fluid-soil-structure interaction is relevant and materials of that kind are present. Dam-reservoir systems and harbor structures are examples of civil engineering constructions where those effects are signifi...
