CHARACTERISTICS OF TOPOGRAPHIC CHAGE FOCUSED ON THE VARIATION OF DRY BULK DENSITY BY SLIP-OUT

Abstract

 We conducted numerical analysis on changes in dry bulk density, hydraulic experiments on changes in fine particle fraction under uniform flow. The effect of the change in density on the change characteristics of the topography consisting of mixed sediment was investigated. As a result, when considering the total suspended amount, in sandy mixed earth and sand, it was suggested that it is necessary to consider the increase in the total suspended amount due to the increase in the proportion of fine particles and the decrease in the suspended amount due to the increase in the adhesive strength in the adhesive mixed sediment and sand.
