OverFlowFormula Properties

The level of the weir crest. For structures with control, this is the initial creste level only. Type: River Structure Geometry Unit: [m] Default: 0

Integere indicating which weir type it is: 1: Rectangular 2: V-Notch 3: Trapezoidal 4: Irregular 5: Long weir

The width of the weir. Type: River Structure Geometry Unit: [m] Default: 0

For structure with control, the crest level may change. Use this property to get/set the current crest level.

ID of the table where the Q-h relation is located.

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]

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

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.

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

Invert level down stream

Invert level up stream

Coeffcient used to determine overall flow coefficient when weir coefficient is not used. Type: Undefined Unit: [] Default: Undefined

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

Location property.

Maximum crest level

Used when crest level is being controlled

Maximum crest level decrease speed

Used when crest level is being controlled

Maximum crest level increase speed

Used when crest level is being controlled

Calculation method: 1 for a Q-h table and 2 for weir formula Default: 2

Minimum crest level

Used when crest level is being controlled

Flag specifying whether the downstream end is out of the system (outlet boundary). If true, flow out of the system is always free outflow (critical flow conditions)

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

Type of structure

String used to identified cross sections

Coefficient used to make a continuos transistion between submerged and not submerged flow at the weir Unit: [] Default: 0.00.

Structure type, unique for each structure.

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

Flag telling if the weir coefficient should be used or the coefficient should be based on the angle of the weir.

Type of the valve Default: None

Flow coeffcient for the weir. If left undefined the flow coeeficient is calculated based on information on the WeirFlowAngle Type: Dimensional factor Unit: [] Default: 0.66

The angle of the weir to the flow direction of the branch Type: Angels Unit: [degrees] Default: 0
