Fig. 6From: The failure of the Stava Valley tailings dams (Northern Italy): numerical analysis of the flow dynamics and rheological propertiesFlow velocity difference, Δv, defined as the difference between the computed (RASH3D) and measured (Takahashi 1991) values. a T: Turbulent rheology; b V: Voellmy rheology; c B: Bingham rheology; d F: Frictional rheology. -t: indication of the test number. In the B-t3, B-t4 and B-t5 tests, the flowing mass stopped before reaching sectional reach 12′-13Back to article page
