Additional Alternatives

On this page you can optionally select additional alternatives to create per unique storm event profile, listed on the left. This is useful if you are using season-based storm event profiles and your hydrology data differs between seasons.

If an alternative type is selected, the alternatives are created as such:

• A new base alternative is created of the alternative type using the label of the first storm event profile in the list.
• For each subsequent storm event profile, a child alternative is created below the base alternative created in the first step.

Using the list of storm event profiles above, a new base alternative is created labeled “50% Summer Profile”. A child alternative of that alternative is then created using the label “75% Winter Profile”.

When using the United Kingdom workflow, this can be useful as you can have additional Hydrology alternatives created.
