Having to simulate a debris flow, which criteria must be considered to best set the resistance coefficient (default = 72)? What is the range of values it can take in a real cases? I have read the information provided in the manual and in the article “Numerical Simulation of a Debris Flow on the Basis of a Two-Dimensional Continuum Body Model” (Hiroshi Takebayashi, Masaharu Fujita), but I don’t understand if it is possible to determine a resistance coefficient based e.g. on physical characteristics of the soil, roughness of the running surface and more.
Thanks in advance for your kindly reply.
