the cross-shore transport Syl is defined by Bakker (1968) as:
Syl = Sy (Yl - Y2 + W)
(82)
where •
Sy = cross-shore transport constant
W = equilibrium distance between beach and inshore.
Similar to the one-line theory the equation of motion for each of the schematized
zones is •
OYl
S 1 =S01 -s 1(83)
Ox

S 2 =So2 -s 2(84)

The above set of differential equations (80) to (84) can be solved numerically or
analytically; the latter only for simplified boundary conditions.
