Boundary Line
Boundary lines can be the Outflow Element of one or more Catchment elements.
If the Flow Boundary is Selected:
- Boundary Flow Type: Choose how to define the flow source. Choose either a time variable hydrograph, or a constant flow.
- Flow: If the Flow Type is Constant simple set the flow value for the current Boundary Point.
- Hydrograph (Surface): If the Flow Type is Hydrograph, click the (…) button in the field to edit the hydrograph.
If the Elevation Boundary is Selected:
- Boundary Elevation Type: Choose how to define the elevation boundary: either a constant value or variable over time.
- Elevation (Constant): If the Boundary Type is constant than this value which applied over the course of the simulation.
- Time-Elevation Curve: If the Boundary Type is Time Series, then can enter how the elevation at the boundary varies over time. Simply, click the (…) button to edit the curve when the field is active.
