Numerical simulations of the dynamic impact force of fluidized debris flows onto structures

The analysis of the dynamic interaction between fluids and solids involves different areas of civil engineering; referring to debris flows, hydraulic and geotechnical engineers devoted specific attention to the triggering (Musso & Olivares 2003), fluidization (Musso et al. 2004, Hungr 2003) and runout phenomena (Iverson 1997) rather than to the impact against structures (Armanini 1997, Scotton & Deganutti 1997).
