ρ
= water density
L
= density of the failed layer
S
= source term
T1
= thickness of the failed layer
t
= time, sec
tc
= characteristic time
to
= time zero
t1
= time, 1 year
τ
= bed share stress
τd
= critical shear stress for deposition
τe
= critical shear stress for particle erosion
τs
= bulk shear strength of the layer
u
= flow velocity in x-direction, m/sec
uom
= maximum orbital velocity of waves
u*
= shear velocity
v
= flow velocity in y-direction, m/sec
γ
= kinematic viscosity of water
= Vs/(Cc)4/3
Vk
Vs
= fall velocity of a sediment particle
V
= mean flow velocity
x
= primary flow direction, m
