�ℎ = ��� vh increases if water depth (H) decreases Causing re-entrainment/scouring
�� = 8 ���� − ��

ρp = specific mass of particle (kg/m3)
ρf = specific mass of water (kg/m3)
f = proportionality constant (0.04 for unigranular sand, 0.06 for more sticky
dp = diameter of particle (m)
g = acceleration of earth (9.81 m/s2)
λ = a function of the Reynold number (0.03)

H
�0 = ��� v0 = the surface loading (to be assumed at 8.3 to 11.1 m/s)
To prevent bottom
scour, vh < vs
