Abstract

Viscous debris flow characterized as high density, ranged from clay to meters boulders and destroyed seriously. Due to disaster always emerged on the deposit process, so this paper began with a survey of literature on deposit process and depositional characteristic of viscous debris flow. By reviewing on the theory model, deposit process and depositional characteristic combined with experiment and field work, found that theory models were too simple to use in natural debris flow. Modeling always ignored some important characteristics, such as scaling effect, boundary effect, time effect, etc. Experiment research also rather limited and can’t consider scale and boundary effect very well. Field work was the only way to recognize the physical feature of debris flow, and it’s very necessary to improve the quality and quantity of the data available in the next work. Reveal the deposition mechanism from a single surge model was proposed to build, which will consider both interstitial flow and coarse granular. Based on real topography, the simulation result will have practical significance in forecasting deposition area and destroy degree in some way.
