The need to understand and predict flows that carry large suspended sediment loads has become acute in the Yellow River basin where significant erosion and siltation associated with hyperconcetrated flood give rise to many river problem. Mud flows, debris flows or slurries, made up of a large amount of clay and/or silt particles suspended in water, often show non-Newtonian properties but remain poorly understood concerning their rheological properties. This paper concerns an experimental study of the rheological properties of mudflows that were investigated by using coaxial cylinder. Shear stress and viscocity of the experimental results have relation with shear rate, sediment concentration, temperature and particle size distribution. In addition the relation between shear stress and shear rate is described by Power law model at low shear rate that shear rate did not fit to Bingham model.
