Output

An 80/80 list of all input data is printed
first (see sample output on page 31). The
end of the input list is noted "END of 80/80
LIST." This means that a COMPUTE card
has been encountered and computations
will follow. The standard output (valley sec-
tion and bridge rating tables) appears next.
Requested optional output (segment and
KD tables and rating curve plots) is inter-
mixed with the rating tables. Only one KD
table and rating curve plot is reproduced
in the sample.
The velocity under the total column in
the segment table is a weighted velocity.
It is the velocity that, when squared and
divided by 2g, yields the velocity head (see
step 3, Valley Section Analysis). Stated an-
other way, it is the average section velocity
adjusted (usually increased) for nonuni-
form velocity distribution within the valley
section.
Each output sheet has its own page iden-
tification. The standard output contains

Helpful Hints

Quite often it is necessary for someone
other than the person who prepares the
input to study the output. For a person un-
familiar with the data, it is much easier to
find specific pieces of information if a set
input pattern is followed. Therefore, the
pattern shown in the sample job is recom-
mended. The standard forms can aid in
coding input in this manner.
The sample job was put together as fol-
lows: The information on form SCS-ENG-16
was put first. The complete reach and road
file was put next on a general input form.
The complete reach and road file should
be put here even if the section information
is split by LINK cards. This was followed by
the SECTION and BPR or CULV informa-

only the page number. The other sheets
contain the same number plus a letter iden-
tification. K for' KD table, P for plotted
rating table, and S for segment information
table. All output sheets pertaining to the
same cross section have the same page
number. The title part of the identification
is indicated by the input title cards. The
points on the plotted rating table are
labeled 0 for lowest cross section eleva-
tion, 1 to 9 for profiles 1 to 9, and A to F
for profiles 10 to 15.

The cost to run the sample job on
the USDA computer (IBM 370 model 168)
in Washington, D.C., was approximately
$17: 22 percent for reading data; 8 percent
for building the section tables of elevation
versus KD, Q'dt" etc.; 8 percent to bal-
ance energy between the valley sections;
1 percent to analyze the bridge; 33 percent
to analyze the culverts; and 28 percent to
print the output (Of which 1 percent was
for printing the rating curve plots).

JOB and ENDRUN cards.

WSP2 requires a large amount of input
data. The user should make every possible
check to eliminate errors. Use of the sort-
routine precludes WSP2 from checking for
correct station (x) values. Section 90963 in
the sample job is a good example of the
use of the sort-routine. After the section
was coded, it was noted that elevation at
the first end of the section was inadequate
The user coded a point at the end of the
section that WSP2 placed at the beginning
of the section. A warning message stating
