"

source--directory containing the
FORTRAN source-code files
(dateJalc.j77. date_conv.f77,
meanday.f77, and rev.mean.f77)
for the four executable program
files that are used in computing
the daily mean discharges and that
are described in the next listings.

dateJaJc.run-file containing the executable
code for a program
(date.JaJc.j77) that calculates the
dates for which a computation of
daily mean discharge is to made
by using either the meanday.run
or rev.mean.run executable files.

dare_conv.run-file containing the executable
code for a program
(dateJonv.j77) that converts a
date to a suitable output formal.

meanday.run-file containing the executable
code for a program (meanday.f77)
that computes the dai I Y mean
discharges at the gaging stations
for the appropriate 24'hour period
(fig. 3).

"

rev. mean. run-file containing the executable
code for a program (rev.mean.f77)
that computes the daily mean
discharges at the gaging stations
for the appropriate 24-hour period
(fig. 3) when there has been a
change in the shi ft data

run_mean.cpl-file containing the computer script
code used to (I) retrieve the 15-
minute interval discharge data
from the streamflow data base, (2)
invoke the programs use to
calculate and reform dates, (3)
invoke the program used to
compute daily mean discharges
from the IS-minute data, and (4)
write the daily mean discharge
data to an output file.

runJev.cpl-file containing the computer script
code having the same functions as
the run_mean.cpl file just

'described, except that the
nmJev.cpl script code is used
when there has been a change in
the shift data for a previous daily
mean discharge computation.

USER MANUAL FOR THE CURRENT
(1997) VERSION OF THE TRANSIT-LOSS
ACCOUNTING PROGRAM

The current (1997) version of the accounting
program certainly is more complex than the original
program described in the first part of this report;
understanding the curren! version depends, in part, on
an understanding of (I) the original accounting
program, including figures 4 and 5; (2) the description
of the two sets of program changes; and (3) the various
input and output files used by the program. This
section contributes (0 the understanding of the current
version of the program by presenting descriptions of
(I) the program options, (2) the data input and some
internal data checks, and (3) additional discussion of
the computational procedures to indicate where and
how the 1991-92 and the 1994-95 program changes
fit in the basic computational procedures (figs. 4
and 5).

Program Options

The first operation of the accounting program is
to load into memory the data in the bsfile.dat file (see
the "Contents of the Trloss Directory" section,
p. 29); these data are used later in the subreach compu-
tations. Once this operation is completed, the program
displays the available program options:

PROGRAM OPTIONS ARE:

1. Compute transilloss for a day in
interactive mode.
2. Analyze diversion alternatives for
current day.
3. Recompute transit loss for
prior day.
4. View/update account tables.
5. Exit.
