The Italian technical standard of construction (NTC-2018) defines the standards for designing, building and testing all kinds of constructions, considering their performances in terms of mechanical resistance, stability and durability. These standards give us the general safety criteria, stating that the effect of actions and material characteristics must be included in the design. Moreover, NTC-2018 transposes requirements suggested in the EN Eurocodes (EN 1990 - EN 1999).

This paper analyses an important aspect of the continuum numerical modelling of rapid landslides as debris flows: “By using the same rheological parameter values, are the results obtained with codes that implement the same constitutive equations, but a different numerical solver, equal?” To answer this question, the two numerical codes RASH3D and GeoFlow_SPH are used here to back-analyse the debris flow event that occurred in the Nora stream (northwestern Italian Alps) in October 2000.
