| 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 the velocity for a debris flow. |
