IBroadCrestedWeir Interface |
Interface for the special weir. Gives access to the Weir geometry data (Datum and LevelWidth) and to
the cross section data for up- and down- stream cross sections.

SyntaxThe IBroadCrestedWeir type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | dDischargedDownStreamWaterLevel |
Calculated Discharge derivative with UpStreamWaterLevel. Upstream is relative to the direction of chainage.
Unit: [m^2/s]
(Inherited from IStructure.) |
| dDischargedUpStreamWaterLevel |
Calculated Discharge derivative with DownStreamWaterLevel. Downstream is relative to the direction of chainage.
Unit: [m^2/s]
(Inherited from IStructure.) |
| Delhs |
Level from where the variation is forced to be linear.
(Inherited from ILinearZeroVariation.) |
| Discharge |
Calculated Discharge
Unit: [m^3/s]
(Inherited from IStructure.) |
| DownstreamWaterLevel |
Downstream water level.Downstream refers to the direction of chainge. The water level is set by use of
SetWaterLevels
Unit: [m]
(Inherited from IStructure.) |
| FlowFactor |
The discharge (and discharge derivatives) are scaled by the flow factor.
(Inherited from IStructure.) |
| FreeOverFlowQHRelations |
Table that specifies the relations betweem upstream water level, discharge, water level at the weir,
and flow area. The relations holds for critical flow only, i.e. for flow that is not influenced by
the downstream waterlevel. Data are specified for both positive and negtive flow (HPos and HNeg).

| HeadLossFreeOverflowNegativeFlow |
Free overflow factor for negative flow.
(Inherited from IHeadLossStructure.) |
| HeadLossFreeOverflowPositiveFlow |
Free overflow factor for positive flow.
(Inherited from IHeadLossStructure.) |
| HeadLossInflowNegativeFlow |
Inflow head loss factor for negative flow.
(Inherited from IHeadLossStructure.) |
| HeadLossInflowPositiveFlow |
Inflow head loss factor for positive flow.
(Inherited from IHeadLossStructure.) |
| HeadLossOutflowNegativeFlow |
Outflow head loss factor for negative flow.
(Inherited from IHeadLossStructure.) |
| HeadLossOutflowPositiveFlow |
Outflow head loss factor for positive flow.
(Inherited from IHeadLossStructure.) |
| HorizontalOffSetFromMarker2 |
Horizontal offset of the structures compared to its limiting cross sections.
(Inherited from IPlotableStructure.) |
| ID |
Name of the structure.
(Inherited from IStructure.) |
| IDInUserUnit | Obsolete.
Used to get a consistent description of the structure. The ID comes in user units. Used e.g. when
reporting errors, warnings and hints.
(Inherited from IStructure.) |
| Implicit |
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
(Inherited from IStructure.) |
| InvertLevelDownstream |
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.
(Inherited from IStructure.) |
| InvertLevelUpstream |
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.
(Inherited from IStructure.) |
| Length | Obsolete.
Length of the structure.
Unit: [m]
(Inherited from IStructure.) |
| Location |
Location of structure.
(Inherited from IStructure.) |
| PartOfCompositeFlow |
Part of the flow in a parallel strucutre that passes through this structure.
(Inherited from ISolvesEnergyEquation.) |
| RunTimeDiagnostics |
The getter is used to get a list of errors. OBSOLETE
(Inherited from IStructure.) |
| SideStructureBank |
Bank side that side-structure is located on
(Inherited from IStructure.)If side structure contains reservoir, and has the Coordinate set, this is not used (and should be set to Undefined). |
| SideStructureReservoir |
Reservoir at end of side structure. Null if not side structure, or no reservoir is defined
(Inherited from IStructure.) |
| SpecialWeir |
Flag specifying whether the special weir formulation is enabled.
For the special weir, the Q-h relations are defined by the user, and the WeirGeometry is not used and need not be defined. The CalculateFreeOverFlowQhRelation(Int32) will have no effect. |
| StructureIterationCentering |
Used when making relaxation when iterating to find the subcritical solution for structures solved using the energy equation.
When it equals 1 no relaxation is made.
(Inherited from IHeadLossStructure.) |
| StructureType |
Type of structure
(Inherited from IStructure.) |
| TopoID |
TopoID used when structure is searching for neighboring cross sections in the reach.
(Inherited from IStructure.) |
| Type |
Structure type, unique for each type of structure.
(Inherited from IStructure.) |
| UpstreamWaterLevel |
Upstream water level. Upstream refers to the direction of chainage. The water level is set by use of
SetWaterLevels
Unit: [m]
(Inherited from IStructure.) |
| Valve |
Type of valve giving the direction of flow that is possible.
(Inherited from IValvedStructure.) |
| WeirGeometry |
Weir geometry
