Boundary Point

The Boundary point provides a point source for either flow injection onto (or removal from) the computational grid during the 2D simulation. Positive flows are injected on the corresponding grid cell at that point, whereas negatively signed flows provide for outflow via that single grid cell.

Boundary points can be the Outflow Element of one or more Catchment elements.

The boundary point has the following properties:
  • 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.

See 2D Boundary Conditions.
