* The 'F1' data line contains Extran orifice data (Max of 200).
*============================================================================
* F1 line :
* NJUNC(1) : Junction number containing orifice, or
* junction name (enter in single quotes).
* NJUNC(2) : Junction number to which orifice discharges, or
* junction name (enter in single quotes).
* NKLASS : Type of orifice.
* = 1 Side outlet circular.
* = 2 Bottom outlet circular.
* = 3 Side outlet rectangular.
* = 4 Bottom outlet rectangular.
* = -1 Time-history side outlet circular orifice
* with data entered on data group F2.
* = -2 Time-history bottom outlet circular orifice
* with data entered on data group F2.
* = -3 Time-history side outlet rectangular orifice
* with data entered on data group F2.
* = -4 Time-history bottom outlet rectangular orifice,
* with data entered on data group F2.
* = 11 Side outlet circular orifice with timed closure
* with control data entered on data group F3.
* = 12 Bottom outlet circular orifice with timed closure
* with gated control data entered on data group F3.
* = 13 Side outlet rectangular orifice with timed closure
* with gated control data entered on data group F3.
* = 14 Bottom outlet rectangular orifice with timed
* closure with gated control data entered on data
* group F3.
* = 21 Side outlet circular orifice with head-dependent
* gated control with data entered on data group F4.
* = 22 Bottom outlet circular orifice with head-dependent
* gated control with data entered on data group F4.
* = 23 Side outlet rectangular orifice with head-dependent
* gated control with data entered on data group F4.
* = 24 Bottom outlet rectangular orifice with head-
* dependent gated control data entered on data
* group F4.
* AORIF : Orifice area, ft2 [m2]. Required only for circular
* orifices. Area for rectangular orifices computed from
* width and depth. Opened/closed area for types 11
* through 14 and 21 through 24.
* CORIF : Orifice discharge coefficient.
* Enter as a negative number if you want the invert
* elevation to change as the orifice opens and closes for
* time history, time closure, and head-dependent closure
* (e.g., inflatable dam). In this case, Zp should
* equal ZP when the orifice or gate is fully opened.
* ZP : Distance of orifice invert above junction
* invert (define only for side outlet orifices), ft [m].
* DEEPO : Vertical depth or height of rectangular orifice
* opening, ft [m].
* Not required for circular orifices.
* WIDEO : Horizontal width of rectangular orifice opening, ft [m].
* Not required for circular orifices.
* Note that DEEPO and WIDEO are interchangeable for
* bottom outlet rectangular orifices.
* DEEPO, WIDEO, AORIF define "open" dimensions for time
* closure and head-dependent orifices.
*
*============================================================================
* Enter time-history orifice data on line F2.
* Each F2 line follows the appropriate F1 line.
* Maximum of 50 time-history orifices.
*============================================================================
* F2 line :
* NTIME : Number of data points to describe the time
* history of the orifice (50 max.).
* VORIF(1,1) : First time, hours, that the orifice discharge
* coefficient and area change values from initial
* settings of group F1 above. Time zero refers to
* beginning (midnight) of beginning day of simulation.
* E.g., VORIF(I,1,1) = 22.0 means first change in
* orifice setting occurs at 10:00 p.m. on first day of
* simulation. Increase hours past 24 (e.g., 25, 26)
* for multi-day simulations.
* VORIF(1,2) : First new value of orifice discharge coefficient.
* VORIF(1,3) : First new value of orifice area, ft2 [m2].
* For rectangular orifices, only the depth is adjusted;
* the orifice width remains unchanged.
*
* Repeat for NTIME values of time/coefficient/area.
* Only one F2 group identifier is required, on the
* first data line. Subsequent lines (if required)
* should not include F2 identifier.
*============================================================================
* Enter timed closure gated control orifice data on line F3.
* Each F3 line follows the appropriate F1 line.
*============================================================================
* F3 line :
* ICNODE : Control junction at which the depth controls the opening
* and closing of the gate. Can be any junction in the system.
* OOPEN : Depth at control junction at which the gate opens, ft [m].
* OCLOSE : Depth at control junction at which the gate closes, ft [m].
* If OOPEN is greater than OCLOSE, the gate is open when
* depths are greater than OOPEN and closed when depths are
* less than OCLOSE.
* If OOPEN is less than OCLOSE, the gate is open when
* depths are less than OOPEN and closed when depths are
* greater than OCLOSE.
* OCAREA : Close orifice area, ft2 [m2]. In circular orifices,
* the diameter changes to match the area. In rectangular
* orifices, only the depth changes and the width remains
* unchanged.
* ORATE : Time required to move gate from open position to closed
* position or vice versa, hours. This controls the maximum
* rate of gate opening or closing during any time step.
* IDIR : Flow direction control
* = -1 Flow is only in the upstream direction when
* gate is open.
* = 0 Flow is in both directions when gate is open.
* = 1 Flow is in downstream direction when gate is open.
* IOPRNT : Controls intermediate output summary
* = 0 No intermediate output summary is produced.
* = 1 Intermediate output includes summary of orifice
* data each time a change is made in the orifice area.
*============================================================================
* Enter head-dependent gated control orifice data on line F4.
* Each F4 line follows the appropriate F1 line.
*============================================================================
* F4 line :
* ICNODE : Control junction at which the depth controls the opening
* and closing of the gate. Can be any junction in
* the system.
* OOPEN : Depth at control junction at which the gate is fully
* open, ft [m].
* OCLOSE : Depth at control junction at which the gate is fully
* closed, ft [m].
* If OOPEN is greater than OCLOSE, the gate is open when
* depths are greater than OOPEN and closed when depths are
* less than OCLOSE.
* If OOPEN is less than OCLOSE, the gate is open when
* depths are less than OOPEN and closed when depths are
* greater than OCLOSE.
* If depths are between OOPEN and OCLOSED, the gate
* opening is linearly interpolated between the open
* area and the closed area.
* OCAREA : Close orifice area, ft2 [m2]. In circular orifices,
* the diameter changes to match the area. In rectangular
* orifices, only the depth changes and the width remains
* unchanged.
* ORATE : Time required to move gate from open position to closed
* position or vice versa, hours. This controls the
* maximum rate of gate opening or closing during any
* time step.
* IDIR : Flow direction control
* = -1 Flow is only in the upstream direction when gate
* is open.
* = 0 Flow is in both directions when gate is open.
* = 1 Flow is in downstream direction when gate is open.
* IOPRNT : Controls intermediate output summary
* = 0 No intermediate output summary is produced.
* = 1 Intermediate output includes summary of orifice
* data each time a change is made in the orifice area.
