Advancing the understanding of sediment mobilisation and trans-port becomes essential for better understanding anthropogenic foot-prints in coastal zones and supporting practical strategies for sustain-able development of ocean resources. Many factors such as waves,currents, multi-scale meteorological events,

where F is the erosion flux; E is a parameter that characterises the
bottom sediment properties; $\tau$ is the bottom shear stress induced by
waves and currents; $\tau_{cr}$ cr is the critical shear stress required for erosion;
and n is a constant ranging from 2 to 6 in the existing literature
