Enter culvert geometry and hydraulic data for up to 5 culverts on the "Culvert Data" sheet (and "User Shape" sheets if necessary). Enter up to 10 boundary condition scenarios to be analysed.

Click the "XS Plot" button to verify accuracy of input geometry data. Click the "XS Properties" button to view a table of culvert properties including area, wetted perimeter, and hydraulic radius.

Click the "Calculate" button to generate flow profiles through each of the selected pipes for each of the specified boundary condition scenarios. If input errors are detected, the "Errors" sheet will appear, with information on the errors. Otherwise, results will appear in the "Summary", "Profiles" and "Profile Plot" sheets. The profile shown on the "Profile Plot" sheet can be selected by pressing the "Plot Profile" button on the "Profiles" sheet. Clicking on the "Culvert Data" sheet tab will hide the output sheets and enable a new analysis.
