Before revision: By using the shear stress velocity, the Shields parameter can also be written as: where: is de dimensieloze korreldichtheid Shields found that the parameter is a function of , in which is the kinematic viscosity.
After revision: By using the shear stress velocity, the Shields parameter can also be written as: where: is the dimensionless grainsize Shields found that the parameter is a function of , in which is the kinematic viscosity.
