forms are being completed propr'rly. Then
they may be sent directly to the nlost conven-
ient Geological Survey computer center.

Request that cards be punched and verified.
Verification will usually eliminate keypunch
errors and will reduce the number of costly
reruns and erroneous answers.

Specifications for job control cards have
been frequently changed in the past and have
varied among the Computer Center Division
terminals. Therefore, information on job
control cards should be obtained from the hy-
draulic specialist or from the nearest com-
puter center.

All requests for processing of computations
should include the following:

(a) User registration code assigned by
Computer Center Division.

(b) Account number to be charged.

(c) Estimated execution time in minutes.
Estimate the time for 1-25 "culverts as 2 min-
utes, 26-50 culverts as 3 minutes.

(d) Estimated lines of printout, in thou-
sands of lines. Estimate lines at) 200 times
the number of" culverts..

(e) Userls name and mailing address.

(f) Program number A526.

COMPUTATION

Card Deck

The data on form 9-1695 will be punched
on cards just as they are entered on the form.
The keypunch operator is in no position to de-
cide whether or not the data submitted are
correcf.

Printout

There are four sections of printout: U)
the input data as punched on the cards, (2)
approach- section properties, (3) barrel-
section properties, and (4) output data asso-
~iated wjth the stage-discharge relation.
See the example on page 16 for details.

The values of C in the printout are those
tabulated on the input form after adjustment
for all pertinent conditions, such as by k ,
r
k , and k . but not for the degree of
