IBroadCrestedWeir Properties

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]

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

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

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).

Free overflow factor for negative flow.

Free overflow factor for positive flow.

Inflow head loss factor for negative flow.

Inflow head loss factor for positive flow.

Outflow head loss factor for negative flow.

Outflow head loss factor for positive flow.

Horizontal offset of the structures compared to its limiting cross sections.

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.

Length of the structure. Unit: [m]

Location of structure.

Part of the flow in a parallel strucutre that passes through this structure.

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

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.

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.

Type of structure

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]

Type of valve giving the direction of flow that is possible.
