Idealized
inlet
model
research
facility
that
may
be adjusted
for
one,
two,
or three
bay
channels
or a
uniform
flow
across
the
bay.
Water is
either
released
(flood
flow)
or
taken
from
(ebb
flow)
the
ocean
headbay to complete the
circulation
energized by the
pumps
located
in the
upper
right
side
of
Figure
2.
Figure
3
shows
bottom
contours at a
1:50
scale.
The
ocean-side
parallel
contours were
specified
by
applying
an
equilibrium
profile
equation
from
Dean
(1977):
d
=
Ax
0.67
(1)
where
d
=
still-water
depth
x =
distance
offshore
and
A
is
determined
by sediment
characteristics.
A
value
of
A
=
0.24
ft
1/3
was
specified
to
represent
a
relatively
steep
beach.
The
contoured
beach
slope
extends to the 18.3-cm
(0.6-ft)
mean
low
water
(mlw)
depth
(or
9.1
m
(30
ft)
scaled
by
1:50).
The
inlet
throat
region
converges
to a
depth
of
15.2
cm
(or
if
scaled
to
1:50,
to a
depth
of
7.6
m
(25
ft))
relative
to an
mlw
datum.
The
minimum
width
is
267
cm
(8.76
ft)
(or
if
scaled
by
1:50,
133.4
m
(438
ft))
across
the
inlet
between
mlw
contours.
Figure
4
shows
the
inlet
with
a
parallel
jetty
configuration.
