HRBridge Properties

Back water ratio table

(Inherited from BridgeBase.)

BridgeGeometry

Overflow

Submergence

Holds the filename and path of the bridge table file

Holds the header for the columns, the upstream water levels. Type : Water level Unit: [meter] Default: 0.0

Number of tubes for conveyance tube analyses.

(Inherited from BridgeBase.)

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

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

Linear flow variation. For water level differences less than delhs use a linear Q variation between h1-h2=delhs and h1-h2=0. This is to avoid stability problems for small water level differences where dQdh goes to infinity. Unit: [m] Default: 0.01

Calculated Discharge. The value is calculated by SetWaterLevels. Unit: [m^3/s]

(Inherited from BridgeBase.)

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

Boolean telling if Enchroachment regenerate

Property used by (de)serializer, when it can not find proper target for a data field. Support of forward compatible data contracts.

Flow area through structure. Used by most (but not all) structures.

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

Slotsize of table downstream

Slotsize of table upstream

Structure ID

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 dicharge are always zero. Default value: true

(Inherited from BridgeBase.)

Boolean telling whether to use IsAsymmetric

Boolean telling whether to use IsMultiWayOpen

Length of the structure. Unit: [m] Default value: 0m

Location property.

Enum BridgeType defining the Bridge method used

Number of columns in the table

Number of rows in the table

Holds the header for the rows, the downstream water levels. Type : Water level Unit: [meter] Default: 0.0

The getter is used to get a list of errors.

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

(Inherited from BridgeBase.)

(Inherited from BridgeBase.)

Type of structure

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

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

(Inherited from BridgeBase.)

String used to identified cross sections

Structure type, unique for each type 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

Online or offline bridge equations. (calculate on the fly or read from table) Default: true

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
