Step-by-step guide
ICM models culverts as a sequence of culvert inlet, conduit, and culvert outlet. In previous ICM versions, this was done using three links. From 2023.1, it is simplified with a culvert conduit type.
To complete this exercise, open the transportable database .icmt file for this tutorial or continue from the previous lesson.
- From the Explorer, under Database, double-click the 1D River Model to open it on the GeoPlan.
Click Find in GeoPlan.
- Perform a Quick Find for Culv_In.
- Once the culvert is located, Close the Quick Find window.
- On the GeoPlan, zoom out until both Culv_In and the Culv_Out outfall node are in view.
- From the GeoPlan Tools toolbar, expand the New Object Type combo box and select Link.
- On the GeoPlan, draw a new link line between Culv_In and Culv_Out.
- In the Create New Link popup, set the Type to Conduit.
- Click OK.
- In the Conduit inlet Properties window, set the Conduit type to Culvert.
- Set the Shape ID to ARCHSPRUNG.
- Set the Width to 11400.
- Set the Height to 3000.
- Set the Springing height to 500.
- Set the Bottom roughness to 50.000.
- Set the Top roughness to 50.000.
- Set the US invert level to 32.040.
- Set the DS invert level to 31.880.
- Set the Culvert code to 9.
- Set the Reverse flow model to Nominal.
