Influence of Bulk Density and Slope on Debris Flows Deposit Morphology: Physical Modelling

Li, Shuai / Chen, Xiaoqing / Zhou, Gongdan / Song, Dongri / Chen, Jiangang

Abstract Prediction of the runout of a debris flow is of great significance for hazard mitigation. Laboratory tests were carried out to simulate debris flows under different bulk densities and slopes. A linear negative relationship between bulk density and runout-ratio-with and volume was found. Results show that the morphology of the deposited sediment is strongly influenced by the inclination of the channel. Moreover, a new empirical formula has been developed to estimation of inundated volume and runout-ratio-width.
