Comparison of flow resistance relations for debris flows using a one-dimensional finite element simulation model

  title={Comparison of flow resistance relations for debris flows using a one-dimensional finite element simulation model},
  author={Dominique Naef and Dieter Rickenmann and Peter Rutschmann and Brian W. McArdell},
This paper describes a one-dimensional finite element code for debris flows developed to model the flow within a steep channel and the stopping conditions on the fan. The code allows the systematic comparison of a wide variety of previously proposed one-phase flow resistance laws using the same finite element solution method. The onedimensional depth-averaged equations of motion and the numerical model are explained. The model and implementation of the flow resistance relations was validated… CONTINUE READING
