Sediment Fall Velocity
The sediment fall velocity may be user-specified or is calculated using the formula by Soulsby (1997):

where:
v = kinematic viscosity [m2/s]
d = grain size [m]
d* = dimensionless grain size [-].
The dimensionless grain size is given by

where:
s = sediment specific gravity or relative density [-]
g = gravitational constant (9.81 m/s2).
