Discharge Data
There are options to enter discharge data into HY-8: "Minimum, Design, and Maximum", "User-Defined", and "Recurrence". The "Minimum, Design, and Maximum" is the default option and historically was the only option available.
Minimum, Design, and Maximum
HY-8 will perform culvert hydraulic calculations based on the input minimum, design, and maximum discharge values. Calculations comprising the performance curve are made for ten equal discharge intervals between the minimum and maximum values. If desired, input a narrower range of discharges in order to examine culvert performance for a discharge interval of special interest.
MINIMUM DISCHARGE
Lower limit used for the culvert performance curve. Can be edited to a number greater than '0'.
DESIGN DISCHARGE
Discharge for which the culvert will be designed. Always included as one of the points on the performance curve.
MAXIMUM DISCHARGE
Upper limit used for the culvert performance curve.
User-Defined
The user first specifies the number of flows they wish to enter. The user then enters the flows in ascending order (smallest flows at the top, highest at the bottom). The user can assign a name to a flow if desired. If no name is given the name column will not be shown in the results or report.
Recurrence
The user simply specifies the flow next to the recurrence year. The user does not need to enter all the years in the table and any flows that are left at zero will not show up in the results or report.
