Hi,
The data for user defined hydrographs are inputted in the storm file, how to construct the storm file and enter the data for inflow hydrographs are detailed in Table 5-2 of the RORB manual. If you have multiple input hydrographs then they will need to be entered into the storm file in calculation order. You can check the calculation order of the input hydrographs by going to the View tab in the RORB GE, click on “View Calculation Order” and ticking the bottom check box “Code 9 – Inflow / Outflow”.
Kind regards,
Benson
