TI(K)

Time associated with QI(K) inflows: if DHF (card 15)
is non-zero, or if ITEH (card 2) is eq~al to zero,
omit this card, K goes from 1 to ITEH.

NS

Number of cross sections ~sed to describe the channel
and valley downstream of dam: first cross section
should be immediately downstream of dam; last cross
section should be at farthest point downstream of
dam where flood information is desired: other cross
sections can be located as desired by user; maximum
of 90 and minimum of 2 cross sections can be used
to describe the downstream channel valley. Also,
if dynamic routing is used in reservoir, specified
cross sections for reservoir are included as part
of the NS sections with the first cross section
located near ~pstream end of reservoir.
Maximum number of top widths used to describe a cross
section. Maximum allowable value is 8.
Total number of cross sections at which discharge
hydrographs will be plotted; maximum number is
limited to 6. The location of the cross sections,
at which plots are provided, is specified by the
parameter NT(K). which is on card (21). If NTT-O,
no plots are provided. If NTT=a negative val~e
between 1 and 6, the profile plots are s~ppressed.
Parameter to specify the type of outp~t other than
plots which will be provided: if JNK=O, a minimum
of output is provided--this incl~des all input data
and hydrograph plots: if NTT:O, no hydrographs or
other o~tput printed; if JNK:l. reservoir depletion
table printed, profile of downstream crests and
times, and designated hydrographs; if JNK=4,
additional information is printed at each time step
for debugging; if JNK>9, considerable information
is printed for debugging. For normal r~ns JNK = ~
is recommended since eno~gh information is printed
to allow some analysis b~t not excessive o~tput,
JNK can have the following val~es: 0, 1, 4. 5. 9.
10; the higher the number, the more information is
prin ted-out,
Pal'ameter to indicate type of cross-section
smoothing. If KSA<O, then smoothing of cross
sections will be a~tomatically performed. Type of
smoothing is specified on card (22).
Parameter to indicate if flow is supercritical. If
KSUPC-O, flow through entire downstream channel-
valley reach is s~bcritical and no special
treatment is required; if KSUPC-l. the flow is
known to be supercritical throughout the entire
