Gymea street drainage system run with selected individual storms
The file for this example is Gymea IL-Cl Model with Individual Storms.drn, located in the folder C:\ProgramData\Drains among the Lite examples. If this folder is hidden, in File Explorer select the View tab and tick the Show Hidden Items box to make it visible. It has been created from the file used in Example S4 by going to the Project Options window and selecting individual storms:
After closing this sheet and opening Project → Select Major/Minor Storms, you will see this property sheet.
You can then add up to 12 individual major storms and 12 minor storms from the ensembles in this sheet. One of the choices under Storm enables you to select all storms of a particular AEP and burst duration. You can then run the selected storms in a similar way to the runs with ARR 1987 storms.

More detailed information on the selection of storms is available here. The selected storms from the ensembles for each duration can be modelled.
Results for individual storms can be investigated, looking at features that may nor be shown in the ensemble results.
This process can also be applied with other hydrological models - Horton (ILSAX) and the extended rational method (ERM).
