*     'C' data lines describe the conduit links in Extran.

*============================================================================

*     C1 line  :

*     NCOND    : Conduit number (any valid integer), or

*                conduit name (enclose in single quotes).

*     NJUNC(1) : Junction number at upstream end of conduit, or

*                junction name (enclose in single quotes).

*     NJUNC(2) : Junction number at downstream end of conduit, or

*                junction name (enclose in single quotes).

*     QO       : Initial flow, ft3/s [m3/s].

*     NKLASS   : Conduit Shape.

*                =  1  Circular.

*                =  2  Rectangular.

*                =  3  Horseshoe.

*                =  4  Egg.

*                =  5  Basket handle.

*                =  6  Trapezoidal channel.

*                =  7  Parabolic/power function channel.

*                =  8  Irregular (natural) channel.

*                =  9  Horizontal Ellipse (longest axis is horizontal)

*                = 10  Vertical Ellipse (longest axis is vertical

*                = 11  Arch

*                = 12  Bridge

*                     Note: Conduit shapes 9, 10, 11 must be entered

*                           as standard pipe sizes.  See file named

*                           SHAPE.DOC for standard sizes.   The size

*                           code is entered for the DEEP parameter.

*                           If METRIC=1, the standard U.S. sizes, in

*                           inches, will be converted to meters. 

*                     Note: A negative NKLASS(N) creates a flap gate

*                           that will only let water move from the

*                           downstream junction (lower elevation conduit

*                           invert) to the upstream junction (higher 

*                           elevation conduit invert). IF Q>0 THEN Q = 0.

*     AFULL    : Cross-sectional area of conduit, ft2 [m2],

*                enter only for NKLASS 3, 4, and 5.  (Geometric

*                properties for NKLASS 3-5 may be found in Section

*                6 of the main SWMM User's Manual.)

*     DEEP     : Vertical depth of conduit, ft [m] (diameter for NKLASS 1).  

*

*                Not required for NKLASS 8.  For NKLASS 8, if DEEP is 

*                zero then the section depth is computed as the maximum 

*                cross section elevation minus the minimum cross section 

*                elevation.  If flows are not expected to equal the 

*                full-section depth, then entering DEEP less than the 

*                maximum section depth will cause only the bottom 

*                portion of the cross-section data to be used and may 

*                result in improved definition of the cross-section 

*                properties when section is subdivided into 25 

*                equal-depth segments. 

*

*                Optional for ellipse NKLASS 9 and 10 and arch 

*                NKLASS 11. Enter Size Code for standard sizes 

*                summarized in file SHAPE.DOC.TXT. 

*

*If DEEP and WIDE are entered as negative numbers for horizontal

*and vertical elliptical pipes, then the full-flow area (Afull) and

*full-flow hydraulic radius (Rfull) will be approximated as a

*function of the minor axis length (AMINOR) as follows :

*

*          Afull = 1.2692 * AMINOR * AMINOR

*          Rfull = 0.3061 * AMINOR

*

*If DEEP and WIDE are entered as negative numbers for arch pipes,

*the full flow area (Afull) and full flow hydraulic radius

*(Rfull) will be approximated as the following:

*

*          Afull = 0.7879 * DEEP * WIDE

*          Rfull = 0.2991 * DEEP

*

*     WIDE     : Maximum width of conduit, ft [m].

*                Bottom width for trapezoid, ft [m].

*                Top width for parabolic/power function, ft [m].

*                Not required (see above) for NKLASS 1,8,9,10, or 11.

*     LEN      : Length of conduit, ft [m]. 

*                For irregular channels NKLASS 8, by default LEN on the 

*                C1 line must equal LEN entered on the C3 or X1 line.  

*                See IWLEN on the BA line options to modify the input of 

*                length for irregular channels.

*

*                Note: A negative LEN(N) creates a flap gate

*                      that will only let water move from the

*                      upstream junction (higher elevation conduit invert)

*                      to the downstream junction (lower elevation conduit

*                      invert).  IF Q < 0 THEN Q = 0

*     ZP(1)    : Distance of conduit invert above junction invert

*                at NJUNC(1), ft [m].

*     ZP(2)    : Distance of conduit invert above junction invert

*                at NJUNC(2), ft [m].

*                Note: If JELEV on line BB is nonzero then ZP(1) and ZP(2)

*                      are actual elevations referenced to an absolute

*                      datum.

*     ROUGH    : Manning's N coefficient (should include entrance, exit,

*                expansion, and contraction losses if NEQUAL on line B2

*                equals 0 or 1).  Not required for NKLASS 8.  Uses XNCH in 

*                data group C2.

*     STHETA   : Slope of one side of trapezoid.  Required only for

*                NKLASS = 6, (horizontal/vertical; 0 = vertical walls).

*

*                For NKLASS 7, the channel exponent(2.0, 3.0, etc.).

*

*                For NKLASS 8, the cross-section identification number

*                (SECNO, group C3) of the cross section used for

*                this Extran channel.  Unlike HEC-2, Extran uses only

*                a single cross section to represent a natural

*                channel reach for NKLASS 8 channels.  A negative

*                STHETA(N) will eliminate the printing of the dimension-

*                less curves associated with each natural channel or

*                power-function channel.

*

*                For NKLASS 12, the bridge section identification number

*                (BRDGNO, group C5) of the bridge data input to use for

*                this Extran conduit.  Note: AFULL, DEEP, WIDE, AND ROUGH

*                are computed from bridge input data.

*

*                Alphanumeric inputs cannot be used for STHETA !!

*

*                For closed conduits (other than NKLASS 6, 7, 8, and 12),

*                STHETA can be used to limit the maximum negative flow

*                in a conduit.  Enter maximum negative flow as a negative

*                number.  Note that this is in the direction adopted by

*                Extran (i.e., negative flow is from end of conduit

*                with lower invert to end of conduit with higher invert).

*                Entering a positive flow may produce unexpected results.

*

*     SPHI     : Slope of other side of trapezoid. Required only for

*                NKLASS = 6, (horizontal/vertical; 0 = vertical walls).

*

*                The average channel slope for NKLASS 8 or 12.

*                This slope is used only for developing a rating

*                curve for the channel.  Routing calculations use invert

*                elevation differences divided by length.  If a slope

*                approximately equal to the true slope, or HGL slope

*                is used, than the capacities listed for the section will

*                approximate the actual capacity.

*

*                SPHI can also be used to limit the maximum positive

*                flow in a conduit.  For NKLASS other than 6, 8, 7, or 12

*                enter a non-zero SPHI to use this option.

*                The maximum flow in the conduit is then limited to

*                this value:  IF Q > SPHI THEN Q = SPHI

*                Note that positive flow in Extran is defined as flow

*                from end of the conduit with the higher invert elevation

*                to the end of the conduit with the lower invert elevation.

*                Entering a negative number may produce unexpected results.

*

*

*   The following parameters are read for closed conduits (NKLASS 1, 2,

*   3, 4, 5, 9, 10, and 11 when NEQUAL on card group B2 is set equal

*   to 2, 3, 4, or 5.  The loss coefficients are then incorporated into

*   the Manning's roughness value used for the conduit.  

*     ENTK     : Entrance loss coefficient.

*     EXITK    : Exit loss coefficient.

*     OTHERK   : Additional loss coefficient for losses other than entrance

*                and exit losses, e.g., expansions, contractions, bends

*                and valves.

*

*   The following parameter is read if IPIPESED on line BB is set equal 

*   to 1.  While it is read for all conduit shapes, this option works 

*   for only circular conduits in this version of the program.

*     SEDEPTH  : Depth of sediment in the conduit in feet.  Full depth, 

*                area, hydraulic radius, and flow capacity will be 

*                adjusted accordingly.  Conduit invert (ZP values) 

*                are adjusted for depth of sediment.  Conduit shape 

*                characteristics used to compute flow at partial depths

*                (e.g., curves relating area, hydraulic radius, and 

*                wetted perimeter to depth) are adjusted accordingly.  

*                JELEV does not affect this input.

*  OPTIONAL CS DATA LINE to read or save irregular cross-section data

* on file associated with NSCRAT(4).

=======================================================================

*     CS line  :

*     IREAD    : Alphanumeric indicator variable (enclose in single quotes).

*                = 'SAVE', save C2, C3 and C4 data to NSCRAT(4).

*                = 'READ', read C2, C3 and C4 data from NSCRAT(4) and

*                   do not read any irregular crosssection data from

*                   C2, C3 and C4 lines in this input file.

*=======================================================================

*CS  'SAVE'

*=======================================================================

*        The C2 (NC), C3 (X1), and C4 (GR) data lines are for any NKLASS 8

*   conduit.  They follow as a group after all C1 lines have been entered.

*   The sequence for channels must be in the same order that they appear 

*   on the C1 lines.  The same cross-sectional information on

*   lines C2-C4 can be used by more than one channel.  I.e., different

*   channels can have the same STHETA values. 

*

*        Data groups C2, C3 and C4 correspond to HEC-2 lines NC,

*   X1 and GR.  HEC-2 input may be used directly if desired.  Lines

*   may be identified either by Extran identifiers (C2, C3, C4) or

*   HEC-2 identifiers (NC, X1, GR).

*============================================================================

*        The C2 line is used to input natural channel roughness.

*   This is an optional data line that permanently modifies the Manning's

*   roughness coefficients (N) for the remaining natural channels.  This

*   data group may be repeated for later channels.  It must be included for

*   the first natural channel modeled.

*============================================================================

*   C2 or NC line :

*         XNL     : n for the left overbank.

*                   = 0.0  No change.

*                   > 0.0  New Manning's N.

*         XNR     : n for the right overbank.

*                   = 0.0  No change.

*                   > 0.0  New Manning's N.

*         XNCH    : n for the channel.

*                   = 0.0  No change.

*                   > 0.0  New Manning's N.

*                   Note:  XNCH is used to develop the normalized

*                          flow routing curves.  Tabulated values

*                          of hydraulic radius account for variability

*                          of n when a constant N (XNCH) is used

*                          during the flow routing process.

*     XLOBR     : Not required for Extran (enter 0.0).

*     LEN       : Length of channel reach represented

*                 by this cross section, ft [m].

*     PXSECR    : Factor to modify the horizontal dimensions

*                 for a cross section.  The distances between

*                 adjacent C4 (GR) stations (STA) are multiplied by

*                 this factor to expand or narrow a cross section,

*                 including STCHL and STCHR on this line.

*                 The STA of the first C4 (GR) point remains the same.

*                 The factor can apply to a repeated cross section

*                 or a current one.  A factor of 1.1 will increase

*                 the horizontal distance between the C4 (GR) stations

*                 by 10 percent.  Enter 0.0 for no modification.

*     PSXECE    : Constant to be added (+ or -) to C4 (GR)

*                 elevation data on next C4 (GR) line.  Enter

*                 0.0 to use C4 (GR) values as entered.

*     EL(1)     : Elevation of cross section at STA(1).  May be

*                 positive or negative, ft [m].  In SWMM Extran the 

*                 elevation-station pairs define the shape of the irregular 

*                 cross section.  The elevations are adjusted such that the 

*                 minimum cross-section elevation equals the elevation of 

*                 the channel invert specified by the Zp on the C1 lines 

*                 and the elevation of the upstream and downstream junctions.

*     STA(1)    : Station of cross section 1, ft [m].

*     EL(2)     : Elevation of cross section at STA(2), ft [m].

*     STA(2)    : Station of cross section 2, ft [m].

*

*        Enter NUMST elevations and stations to describe the cross section.

*  Enter 5 pairs of elevations and stations per data line.  (Include group

*  identifier, C4 or GR, on each line.)  Stations must be in increasing

*  order progressing from left to right across the section.  Cross-section

*  data are traditionally oriented looking downstream (HEC, 1982).
