Bentley StormCAD lets you add tidal curves to outfalls in your model. You define a tidal curve for an outfall as a Time vs. Elevation curve.

To add a Cyclic Time vs. Elevation curve to an outfall:

1. Click an outfall in your model to display the Property Editor, or right-click an outfall and select Properties from the shortcut menu.
2. In the Boundary Condition section of the Property Editor, select Tidal in the Boundary Condition Type field. The Cyclic Time-Elevation Curve field becomes available.
3. Click the Ellipses (...) button next to the Cyclic Time-Elevation Curve field.
4. In the Cyclic Time-Elevation Curve dialog box, each row in the table represents a point on the Cyclic Time-Elevation curve. Type values for Time and Elevation for each row. Click the New button to add a row or press the Tab key to advance to the next field in the table.
5. Perform the following optional steps:
6. To delete a row from the table, select the row then click Delete.
7. To view a report on the curve, click Report.
8. To view a plot of the curve, click Graph.
9. Click OK to close the dialog box and save your curve data in the Property Editor.
