Can I apply rainfall uplift factors for climate change assessments?

You can add a climate change factor to any FEH13 design rainfall return period using the ReFH 2.3 model.

These should be entered as a factor e.g., enter 1.3 for a 30% climate change uplift to the rainfall. This creates additional design rainfall series; the name will identify it as a climate-change adjusted series, e.g., “10 year 1.3 CC”.
