Abstract This study proposes a comprehensive method, which consists of field
investigation, flume test and numerical simulation, to predict the velocity and sediment
thickness of debris flow. The velocity and sediment thickness of the debris flow in
mountainous areas can provide critical data to evaluate the geohazard, which will in turn
help to understand the debris runout. The flume test of this debris prototype can provide
friction coefficient and viscosity coefficient which are important for numerical simulation
of debris flow. The relation between the key parameters in the numerical modelling using
the Voellmy model and debris-flow rheology is discussed. Through simulation… More >
