You can define an inflow collection for any node element in Bentley StormCAD . An inflow collection can contain any combination of fixed, hydrograph, or pattern inflows. An inflow collection can contain any combination of fixed and hydrograph inflows.

To define an inflow collection:

1. Click a node element in your model to display the Property Editor, or right-click a node element and select Properties from the shortcut menu.
2. In the Inflow Collection section of the Property Editor, click the Ellipses (...) button. The Inflow Collection Editor appears.
3. Click the New button, then select the type of inflow you want to create from the submenu (Fixed Inflow, Hydrograph Inflow, Pattern Inflow).
4. For a Hydrograph Inflow, enter the data points in the hydrograph table. For Fixed and Pattern Inflows, enter the data in the appropriate fields. For a hydrograph, if the last time in the table is less than the total simulation time, the simulation time and last flow will be appended to the hydrograph table.
5. Repeat steps 3 and 4 for each inflow you want to add to the collection.
6. Click the Composite Hydrograph button to see a graph of the composite hydrograph.
7. Click the Composite HydrographData Table button to see a tabular view of all the data points in the composite hydrograph.
8. Click OK to close the dialog box and add the collection data to the Property Editor.

Inflow Collection Editor

This dialog box lets you define fixed loads, hydrograph loads, and pattern inflows for any node element. A node may have any combination of fixed loads, hydrograph loads, and pattern inflows.

The dialog box contains an Inflow list pane and the following controls:

The Inflow Collection Editor also contains the following controls:
