Input

Control words in columns 1 through 10
of the input cards direct the storage of
data and the operation of the program.
Spelling must be exact, but the user can
insert blanks in control words as desired.
If data are entered that are not needed,
they are simply ignored. Some data are
optional. For example, if acres flooded in-
formation is unimportant only the first two
length fields on the reach card need to be
coded.
WSP2 disregards blanks inserted within
digits. For example, both 2379bbbbbb and
b237b9bbbb are read as 2379.0 (b repre-
sents a. blank column in an input field). If
the correct input is 23.79, the user must
insert the decimal point.

Card Entry Order

The major requirement is that all data
needed to perform a compute instruction
must precede the COMPUTE card. The
order of REACH and ROAD cards estab-
lishes the order of computations that follow
after a COMPUTE card is read. The user
must place these cards in the desired order
but the cards need not be adjacent to each
other in the input deck. The input cards
th"t must be in a specific location are:

1. The first card of any job must be a WSP2
card.
2. REACH and ROAD cards must be in the
order of computation,
3. For bridge openings, the BPR or CONTR
card must be first. If a PIER card is used,
it must follow the BPR card. The GIRDER
cards must be last in the'set, followed by
an END TABLE card.
4. A CULV2 card must foliow each CULV1
card.
5. An NVALUE card must foliow each
SEGMENT card.
6. A REACH2 card (if used) must follow the
REACH card. Since the flood-plain velocity
option is not yet operational, the REACH2
card should be used only if the valley sec-
tion of that reach has the same shape as
the valley section of another reach. The
valley section that is displaced and copied
can be either upstream br downstream
from the reach under consideration.
7. All information necessary to compute
profiles, such as DISCHARGE, STARTE,
TRIB, etc., for a given compute must pre-
cede the COMPUTE card.
8. A LINK card must be used if a job
exceeds a combined totai of 50 reach and
road sections. The section that precedes
