Bottom level

BridgeGeometry

Overflow

Submergence

Holds the smoothed table Type : Water level or discharge depending on the chosen calculation mode Unit: [m3/s] or [meter] Default: 0.0

Holds the header for the columns Type : Water level Unit: [meter] Default: 0.0

Number of tubes for conveyance tube analyses.

The culvert used otherwise null

Calculated Discharge derivative with UpStreamWaterLevel. Upstream is relative to the direction of chainage. Unit: [m^2/s]

Calculated Discharge derivative with DownStreamWaterLevel. Downstream is relative to the direction of chainage. Unit: [m^2/s]

Level from where the variation is forced to be linear.

Calculated Discharge Unit: [m^3/s]

Loss factor Ratio Dis Coef Type, 0 - Contraction m = (1-M), 1 - Opening m = M

Downstream water level.Downstream refers to the direction of chainge. The water level is set by use of SetWaterLevels Unit: [m]

Dykes1 tables

Dykes2 tables

Eccentricity tables

Boolean telling if Enchroachment regenerate

Entrance tables

The discharge (and discharge derivatives) are scaled by the flow factor.

Froude tables

Slotsize of table downstream

Slotsize of table upstream

Name of the structure.

Used to get a consistent description of the structure. The ID comes in user units. Used e.g. when reporting errors, warnings and hints.

Flag to control if the structure is implicit or explicit. If the structure is explicit (Implicit == false) then the derivatives of the discharge are always zero. Default value: true

Invert level down stream The invert level is the level where water starts flowing in to the structure from the downstream side. It does not necessarily flow through the structure.

Invert level up stream. The invert level is the level where water starts flowing in to the structure from the upstream side. It does not necessarily flow through the structure.

Boolean telling whether to use IsAsymmetric

Boolean telling whether to use IsMultiWayOpen

Length of the structure. Unit: [m]

Location of structure.

Bridge Method - FHWA, USBPR, Energy, HR, Nagler, Yarnell

Piers tables

Road1 tables

Road2 tables

Holds the header for the rows Type : Water level Unit: [meter] Default: 0.0

The getter is used to get a list of errors. OBSOLETE

Bank side that side-structure is located on

If side structure contains reservoir, and has the Coordinate set, this is not used (and should be set to Undefined).

Reservoir at end of side structure. Null if not side structure, or no reservoir is defined

Skew tables

Enum describing Bridge Table smoothing filer, 0 - no filter, 1-3 different filters, -1 - Max filter

Number of iterations the smoothing filter is applied

Type of structure

SubFac tables

Submerged tables

Holds the table Type : Discharge Unit: [m3/s] Default: 0.0

Variable defining maximum number of iterations for precalculating tables.

Boolean telling if the tables are generated

Holds the smoothed table Type : Water level or discharge depending on the chosen calculation mode Unit: [m3/s] or [meter] Default: 0.0

Table input filetype 0 - DFS2 1 - ASCII Default: 0

Theta tables

Top level

TopoID used when structure is searching for neighboring cross sections in the reach.

Structure type, unique for each type of structure.

Upstream water level. Upstream refers to the direction of chainage. The water level is set by use of SetWaterLevels Unit: [m]

The velocity distribution coefficient for bridge calculations is set to unity per default. The coefficient may be calculated based on conveyance distribution. Default value: false

Boolean telling whether to use Eccentricity

The reach length for the FHWA method is determined based on an equal conveyance tube analysis. If the reach length should only be based on the physical distance from the adjacent cross section to the bridge the variable 'USE_FHWA_REACH_LENGTH' may be used.

Boolean telling whether to use overflow

Boolean telling whether to use Piers

Boolean telling wheter to use Piers Piles

Use preprocessed bridge tables

Boolean telling whether to use Skewness

Boolean telling whether to use SpurDykes

Boolean telling whether to use submergence

Datum to be applied to all water levels specified in the table. Type: water level Unit: [meter] Default: 0.0

The weir used otherwise null
