Current Velocity Calculation of Debris Flow Based on Excess-Height in Bend

The current velocity is an important parameter of debris flow, and it is more difficulty to be measured and calculated. Based on analysis to every known calculating formulas of excess-height in bend, the calculating models of excess-height in bend m every debris flows are explored. Further, the formulas calculating current velocity of mudflow, dilute and viscous debris flows based on excess-height in bend are improved, and are tested with real examples.
