This paper shows the conditions of the occurrence of waves on the high viscous flow with solid particles as viscous debris flow surges. And it is discussed about the theoretical and experimental results considering the flow mechanism of the viscous debris flow as a high viscous laminar flow laden with solid particles. Under the rectangular channel, laminar flow condition and the flow with constantly dispersed solid particles in the depth, the occurrence of the roll wave dose not depend on the viscous and concentration of the particles.
