RadialGate Class |
The radial gate divides the flow into an underflow part and an overflow part. When specifying gate
levels for a radial gate the user should specify the level for the underflow part,
i.e. the level of the bottom of the gate. The gate level for the overflow part is then calculated
based on geometric considerations.
The under flow gate is a controllable structure. It allows the gate level to be varied.

SyntaxThe RadialGate type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | RadialGate |

|
Properties| Name | Description | |
|---|---|---|
 | ActualGateLevel |
Actual gate level.
Type: River Structure Geometry
Unit: [m]
Default: 0
(Inherited from Gate.)this is not a setup parameter, but a run parameter, which will change during the run (if the gate is controlled). If the gate is not controlled, this can be used to change the gate (manual/user defined control). |
| dDischargedDownStreamWaterLevel |
Calculated Discharge derivative with DownStreamWaterLevel. Downstream is relative to the direction of chainage.
The value is calculated by SetWaterLevels.
