Abstract

Abstract:

Bioclastic sediments are an important part of marine sediments, and the motion characteristics are the key to study their depositional process. From the characteristics of bioclastic sediments, we summarize the two main characteristics of shape and internal pore space that affect sediment motion. From the experimental studies of settlement, inception and bank evolution, the influence of bioclastic sand properties on sediment motion characteristics was analyzed. Existing studies have only explored the effect of shape on the motion of single-particle bioclastic sediments and lacked the exploration of the motion of clusters of particles. Due to the limitation of the research tools, the influence of internal pore properties on the motion of bioclastic sediments was not discussed. In the future, we should take into account the shape of bioclastic sediments and internal porosity characteristics in the context of oceanic hydrodynamic conditions to characterize the motion of bioclastic sediments, to quantify the influence of the characteristics of bioclastic sediments, and to apply the results to the practical application in order to predict the evolution of the geomorphology of the shore and beach in the environment of bioclastic sedimentation.

Key words: bioclastic sediments, bioclastic sediment characterization, sediment settlement, incipient motion of sediment, beach evolution
