IValve 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.

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

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 flow area of the valve 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 fractions [0;1]).

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

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

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.

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. 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

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.

The opening of the valve in percent. This value is overwritten if RTC is applied. Type: River Structure Geometry Unit: fraction [0;1] Default: 0
