Time patterns of R
slr
(top) and Q
s
(bottom) reconstructed on the basis of the autoretreat model. For calculation of R
slr
,
Q
s
is assumed to have been constant. y
i
(km) is an assumed height of the initial shoreline position at site i, the exact location
of which is not given a priori. Magnitudes of R
slr
and time t are here non-dimensionalised by dividing with R
slr
0P
and t
D
,
respectively, where R
slr
iP
is R
slr
averaged for time interval during which shelf edge migrated from site i to site P and t
D
is time
elapse for shelf-edge migration from the initial point i to site D. On the other hand, for calculation of Q
s,
R
slr
is assumed to
have been constant. Magnitudes of Q
s
are non-dimensionalised by dividing with Q
sMD
, where Q
sMD
is Q
s
averaged for time
interval during which shelf edge migrated from site M to site D. Adopted from Muto & Steel (2002a).
