Effect of structural setting of source volume on rock avalanche mobility and deposit morphology

Abstract. Deposit morphologies and sedimentary characteristics are methods for investigating rock avalanches. The of structural geology source volume, namely the in-place mass structure, will influence these two deposit avalanche mobility. In this study, a series experiments were conducted by setting different initial configurations blocks to simulate specifically including long axis perpendicular strike inclined plate (EP), parallel (LV), (LP), randomly (R) without (NB) as control experiment. experimental materials comprised both cuboid granular large matrixes, respectively, in natural results revealed that mobility flows was enhanced LV, LP R configurations, whereas it restricted EP configuration. decreased with increase slope angles at LV configurations. Strand protrusion made elevation deposits configuration larger than EP, A zigzag structure is created resulting from lateral spreading causing rotate. Varying degrees deflection demonstrated levels collision friction interior flows; most intensive observed EP. deposits, blocks' orientation affected their motion process flows. This research would support studies relating volume landslide morphology.
