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

= Vs/(Cc)4/3

Vk

Vs

= fall velocity of a sediment particle

V

= mean flow velocity

x

= primary flow direction, m

y

= direction perpendicular to x , m

ζ

= local coordinate
