| Zusammenfassung |
| The two-phase fluid model is applied in this study to calculate the
steady velocity of a debris flow along a channel bed. By using the
momentum equations of the solid and liquid phases in the debris flow
together with an empirical formula to describe the interaction
between two phases, the steady velocities of the solid and liquid
phases are obtained theoretically. The comparison of those
velocities obtained by the proposed method with the observed
velocities of two real-world debris flows shows that the proposed
method can estimate accurately the velocity for a debris flow. |
