When you right-click this culvert object, a small menu will open. Selecting Edit Data from this opens the Culvert property sheet in which you can view and enter data.
Following a run, the peak water levels upstream and downstream of a culvert of this type are presented in the Main Window, beside the culvert symbol. Water levels upstream and downstream of culverts can be examined using the Pop-Up (right mouse button) menu that provides options for plotting levels calculated during a run, or for displaying the numerical values.
