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.
-
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.
