Abstract: In this paper, based on the analysis of the ovserved data, a set of theories is proposed of the transport of heper-concentrated sediment, the basic points of which are: (1) The hyperconcentrated flow can be divided into homogeneous and non-homogeneous flow. The former is in the sphere of resistance work, while the latter is in the sphere of suspension work. With the hyperconcentrated flow in natural rivers, including volcanic lava and debris flows, the theory in sediment transport follow the non-equilibrium hyperconcentrated sediment transport theory.
