Dataset for: "Shields diagram and the incipient motion of microplastic particles"

-''incipientMotion.mat'' is a MATLAB binary workspace file containing the particle dimensions, density, and friction velocities (mean and standard deviation) for the incipient motion of all microplastic particle groups, with their friction velocity data calculated from the related lid velocities.

-''incipientMotion.xlsx'' is an Excel worksheet listing the particle number, shape/particle code, material, dimensions, nominal diameter, Corey shape factor, sphericity, density, friction velocities (mean and standard deviation), grain Reynolds number, and critical Shields parameter of all microplastic particle groups. The water density, kinematic viscosity, as well as the median grain size of the bottom sediment are also included. 

-Example experimental videos for each microplastic particle group are provided with the naming convention "Particle_X(Shape).mp4", where “X” refers to the particle group number and “Shape” is the particle shape (e.g. sphere, circular disk, cube, etc.). Please note that the videos are low-quality when using the preview. For optimal quality, it is suggested to download the videos and play the files directly.
