VillemonteWeir Properties |
The VillemonteWeir type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | dDischargedDownStreamWaterLevel |
Calculated Discharge derivative with DownStreamWaterLevel. Downstream is relative to the direction of chainage.
The value is calculated by SetWaterLevels.
Unit: [m^2/s]
(Inherited from Structure.) |
| dDischargedUpStreamWaterLevel |
Calculated Discharge derivative with UpStreamWaterLevel. Upstream is relative to the direction of chainage.
The value is calculated by SetWaterLevels.
Unit: [m^2/s]
(Inherited from Structure.) |
| Delhs |
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
|
| Discharge |
Calculated Discharge. The value is calculated by SetWaterLevels.
Unit: [m^3/s]
(Inherited from Structure.) |
| DownstreamWaterLevel |
Downstream water level.Downstream refers to the direction of chainage. The water level is set by use of
SetWaterLevels
Unit: [m]
(Inherited from Structure.) |
| ExtensionData |
Property used by (de)serializer, when it can not find proper target for
a data field. Support of forward compatible data contracts.
(Inherited from Structure.) |
| FlowArea |
Flow area through structure. Used by most (but not all) structures.
(Inherited from Structure.) |
| FlowFactor |
The discharge (and discharge derivatives) are scaled by the flow factor.
(Inherited from Structure.) |
| Height |
Height above invert level.
Type: River Structure Geometry
Unit: [m]
Default: 1
|
| HorizontalOffSetFromMarker2 |
Value used when plotting the structure
Unit: [m]
Defualt: 0
|
| ID |
Structure ID
(Inherited from Structure.) |
| IDInUserUnit |
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 Structure.) |
| Implicit |
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 Structure.) |
| InvertLevel |
Bottom datum level.
Type: River Structure Geometry
Unit: [m]
Default: 1
|
| InvertLevelDownstream |
Invert level down stream
(Overrides StructureInvertLevelDownstream.) |
| InvertLevelUpstream |
Invert level up stream
(Overrides StructureInvertLevelUpstream.) |
| Length |
Length of the structure.
Unit: [m]
Default value: 0m
(Inherited from Structure.) |
| Location |
Location property.
(Inherited from Structure.) |
| RunTimeDiagnostics |
The getter is used to get a list of errors.
(Inherited from Structure.) |
| SideStructureBank |
Bank side that side-structure is located on
(Inherited from Structure.)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 Structure.) |
| StructureType |
Type of structure
(Inherited from Structure.) |
| TopoID |
String used to identified cross sections
(Inherited from Structure.) |
| Type |
Structure type, unique for each structure.
(Overrides StructureType.) |
| UpstreamWaterLevel |
Upstream water level. Upstream refers to the direction of chainage. The water level is set by use of
SetWaterLevels
Unit: [m]
(Inherited from Structure.) |
| Valve |
Type of the valve
Default: None
(Inherited from ValvedStructure.) |
| WeirCoefficient |
Multiplication factor in the weir formula.
Type: Chezy number
Unit: [m^(1/2)/s]
Default: 1.838
|
| WeirExponent |
Exponential coefficient in the weir formula.
Type: Dimensional factor
Unit: []
Default: 1.5
|
| Width |
Width of the weir opening. Width is perpendicular to the flow direction, i.e. "across the river"
Type: River Structure Geometry
Unit: [m]
Default: 1
