Hi,
I want to run a Monte Carlo analysis using GSDM storm patterns (for a 0.1% AEP event and a small catchment) instead of the regional temporal patterns extracted from the ARR 2016 data hub. What is the best way to prepare the incremental storm pattern file, as I essentially want to create temporal pattern file of Rare events only?

Many thanks,
JV

Hi JV
Thanks for your question. There are two options to achieve the result you are after.

One way would be to select ‘User Defined’ rather than ‘ARR2016’ under IFD Data Type in the Run Specification dialogue box. You will then need to copy and paste your design rainfall data in, but will also be able to provide single temporal patterns for each duration, or a set of Monte Carlo temporal patterns. The MC temporal patterns for this option use the file format similar to the file Melbourne_mc.pat which is available in the sample data folder when you install RORBwin.

The other alternative is simply to use the ARR2016 IFD, but manually edit the ARR Data Hub _increments.csv file to replace the Data Hub temporal patterns with the GSDM temporal patterns. This is probably the more straightforward option.

Hope this helps.
David

Hi David,
Thank you, was leaning towards the second option anyway, but good to have the alternative approach as well.
