HY8 will also allow you to compute the hydraulics of multiple culverts. When choosing the Compute button with this option specified HY8 determines the amount of discharge through each of the culverts as well as the discharge overtopping the roadway. When computing with the multiple culvert option you will see the DOS window shown below. In order for the balance.exe program to finish its computations you must press the Enter key. Once balance completes the computations you can view the full report (on the screen, or sent to a text file or the printer) by selecting the "R" key as directed by the menu at the bottom of the calculations DOS window. You can also get to the report after dismissing the balance DOS window by selecting the View Report button from the main dialog.
