Abstract
Hurricanes
can
benefit
wetland
accretion
by
augmenting
the
delivery
of
mineral
sediment,
an
essential
process
allowing
marshes
to
offset
submergence
during
rising
sea
levels.
Using
Hurricane
Gustav
(2008,
Louisiana)
as
a
control,
we
examined
eight
synthetic
storms
with
varying
characteristics
(track,
speed,
intensity,
size)
evaluate
sediment
exchange
between
inner
shelf
and
bay
bay‐to‐marsh
interfaces.
All
showed
net

marsh—storms
closer
proximity,
higher
slower
forward
speed
positively
correlated

storm
size
had
little
impact.
Except
for
slow‐moving
(½
Gustav),
our
analyses
suggest
that
most
hurricane
scenarios
cause
erosion,
because
more
is
