C32 SURFACE ELEV OR PRESSURE DEPENDENT FLOW INFORMATION

*

* IQCTLU: I INDEX OF UPSTREAM OR WITHDRAWAL CELL

* JQCTLU: J INDEX OF UPSTREAM OR WITHDRAWAL CELL

* IQCTLD: I INDEX OF DOWNSTREAM OR RETURN CELL

* JQCTLD: J INDEX OF DOWNSTREAM OR RETURN CELL

* NQCTYP: FLOW CONTROL TYPE

*                = -1 FLOW AS FUNCTION OF UPSTREAM DEPTH (STAGE RATING CURVED)

*                = 0 FLOW AS FUNCTION OF ELEVATION OR PRESSURE DIFFERCENCE TABLE

*                = 1 SAME AS 0 WITH ACCELERATING FLOW (E.G. TIDAL INLET)

*                = 2 FLOW DERIVED FROM UPSTREAM AND DOWNSTREAM WS ELEVATIONS

*                = 3 LOWER CHORD OPTION USING UPSTREAM DEPTH WHEN WSEL > BQCLCE

*                = 4 LOWER CHORD OPTION USING ELEVATION DIFFERENCE WHEN WSEL > BQCLCE

*                = 5 CULVERT

*                = 6 SLUICE GATE

*                = 7 WEIR

*                = 8 ORIFICE

*                = 9 FLOATING SKIMMER WALL (EE8.1)

*                = 10 SUBMERGED WEIR (EE8.1)

* NQCTLQ: ID NUMBER OF CONTROL CHARACTERIZATION TABLE

* NQCMUL: MULTIPLIER SWITCH FOR FLOWS FROM UPSTREAM CELL

*                = 0 MULT BY 1. FOR CONTROL TABLE IN (L*L*L/T)

*                = 1 MULT BY DY FOR CONTROL TABLE IN (L*L/T) ON U FACE

*                = 2 MULT BY DX FOR CONTROL TABLE IN (L*L/T) ON V FACE

*                = 3 MULT BY DX+DY FOR CONTROL TABLE IN (L*L/T) ON U&V FACES

* HQCTLU: OFFSET FOR UPSTREAM HEAD (m)

* SET TO CELL'S BOTTOM ELEVATION TO USE ELEVATION INSTEAD OF DEPTH FOR NQCTYP = -1 or 3

* HQCTLD: OFFSET FOR DOWNSTREAM HEAD (m)

* QTCLMU: NOT USED

* QTCLMD: NOT USED

* BQCLCE: LOWER CHORD ELEVATION (m) [ONLY USED IF NQCTYP = 3 OR 4]

* NQCMINS: MINIMUM NUMBER OF STEPS REQUIRED ABOVE LOWER CHORD [ONLY USED IF NQCTYP = 3 OR 4]

*

* *** LOOKUP TABLE HEAD DETERMINATION (HUP & HDW) FOR LOW CHORD

* *** NQCTYP = 3: HUP = HP(LU) + HCTLUA(NCTLT) + HQCTLU(NCTL)

* *** NQCTYP = 4: HUP = HP(LU) + BELV(LU) + HCTLUA(NCTLT) + HQCTLU(NCTL)

* *** NQCTYP = 4: HDW = HP(LD) + BELV(LD) + HCTLDA(NCTLT) + HQCTLD(NCTL)

*

*HS_FACTOR: DISCHARGE DISTRIBUTION FACTOR (ONLY USED FOR NQCTYP>4)

*HS_NTIMES: NUMBER OF TIMES HYDRAULIC STRUCTURE DEFINITION CHANGES (IN DEVELOPMENT)

*HS_TRANSITION: NUMBER OF SECONDS TO TRANSITION FROM TIME (T) TO TIME (T+1) (IN DEVELOPMENT)
