Based on the field observation data of debris flow and slurry, the two parameters of the non-dimensional linear cohesion mixed model are modified according to the rheological characteristics of different types of viscous debris flow to obtain the rheological model of high concentration debris flow. Correction of parameters means: (i) Correction of high viscosity media for linear concentration indices; (ii) Correction of volumetric concentration with non-uniform particle composition for ultimate concentration
