Valve Properties

For structure with control, the valve opening may change. Use this property to get/set the current valve opening. Unit: fraction [0;1]

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

The diameter of the valve Type: River Structure Geometry Unit: [m] Default: 0

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.

The flow area of the valve if the gate is fully open Type: River Structure Geometry Unit: [m2] Default: 0

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

Table holding flow factor as a function of opening (as fraction [0;1]).

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

The invert level of the valve Type: River Structure Geometry Unit: [m] Default: 0

Invert level down stream

Invert level up stream

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

Location property.

Maximum valve opening, when valve is controlled Unit: fraction [0;1]

Maximum valve speed, i.e. speed with which it can open and close Unit: [/s] - fraction per second

Minimum valve opening, when valve is controlled Unit: fraction [0;1]

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

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]

Type of the valve Default: None

The opening of the valve as a fraction. This is the initial value only, the actual value may be changed if RTC is applied. Type: River Structure Geometry Unit: fraction [0;1] Default: 0
