Sediment Fall Velocity
The sediment fall velocity may be userspecified or is calculated using the formula by Soulsby (1997):
(1) 
where:
v = kinematic viscosity [m^{2}/s]
d = grain size [m]
d_{*} = dimensionless grain size [].
The dimensionless grain size is given by
(2) 
where:
s = sediment specific gravity or relative density []
g = gravitational constant (9.81 m/s^{2}).
