This

program
...
draws
...
the
...
slopes
...
into
...
the
...
bottom
...
of
...
the
...
floctank
...
to
...
provide
...
access
...
for
...
the
...
water
...
to
...
flow
...
out
...
of
...
the
...
valves
...
when
...
draining.
...
Since
...
drains
...
must
...
always
...
be
...
put
...
in
...
the
...
first
...
and
...
last
...
channels
...
of

the

flocculator,

in

the

event
...
of

an

even

number

of

channels,

there

will

be

two

drains
...
placed

contiguously
...
in

the

channels

closest

to

the

tank.

This

is

the

for

Technical Program Information
1) A new layer, "flocdrainslopes,"
...
is
...
created.
...
2)
...
The
...
slopes
...
are
...
iteratively
...
drawn
...
as
...
wedges
...
in
...
each
...
channel
...
from
...
the
...
channel
...
closest
...
to
...
the
...
sedimentation
...
tank
...
to
...
the
...
channel
...
closest
...
to
...
the
...
entrance
...
tank.
...
- The
...
- width
...
- of
...
- a
...
- slope
...
- is
...
- equal
...
- to
...
- the
...
- diameter
...
- of
...
- the
...
- valves,
...
- the
...
- center
...
- of
...
- which
...
- is
...
- aligned
...
- with
...
- the
...
- middle
...
- of
...
- its
...
- channel.
...
- The
...
- depth
...
- of
...
- the
...
- slope
...
- into
...
- the
...
- bottom
...
- of
...
- the
...
- floctank
...
- is
...
- half
...
- of
...
- a
...
- valve
...
- diameter,
...
- putting
...
- the
...
- center
...
- of
...
- the
...
- opening
...
- at-grade.
...
- The
...
- length
...
- of
...
- the
...
- slope
...
- is
...
- determined
...
- by
...
- setting
...
- the
...
- angle
...
- of
...
- the
...
- slope
...
- to
...
- 30
...
- degrees.
...
- If
...
- the
...
- slope
...
- is
...
- so
...
- long
...
- that
...
- it
...
- extends
...
- beyond
...
- the
...
- nearest
...
- baffle,
...
- the
...
- length
...
- is
...
- recalculated
...
- to
...
- be
...
- 5
...
- cm
...
- away
...
- from
...
- the
...
- nearest
...
- baffle.
...
3)
...
All
...
wedges
...
are
...
unioned.
...
4)
...
The
...
"floctank"
...
layer
...
is
...
thawed
...
so
...
that
...
it
...
may
...
be
...
edited.
...
5)
...
The
...
unioned
...
slopes
...
are
...
subtracted
...
in
...
a
...
single
...
command
...
from
...
the
...
floctank.
...
6)
...
The
...
"floctank"
...
and
...
"drainslopes"
...
layers
...
are
...
frozen.
