Abstract

In this paper, Non-Newtonian character of the mud-flow is discussed upon the baseof the experimental data, and the mean velocity of the mud-flow is calculated as non-Newtonian liquid. The mud flow of the prototype in the mountainous region is con-cluded as the same character as the experimental flow. The boundary shearing stressin a trapezoid section of the mud flow, and the pseudoplastic viscosity of the mud isestimated in order to caluculate the velocity of the mud flow.
