This page summarizes recommended approach for processing a large amount of ARR 2016 ensembles.
==Introduction==
The ARR 2016 guidelines require the use of ten temporal patterns to be applied for each design Annual Exceedance Probability (AEP) and storm duration combination. This multiplies the number of design simulations by ten and requires additional processing in comparison with the previous approach recommended in ARR 1987. TheAs a consequence, the model result filesfolders can get very large, and the creation of thepost processing tools can lead to tedious work andof the computerised processingresults can be time intensive.
==Choice of Output==
As the model results might get large in size the preferred method to process the ensembles is to use FLT grid output format to export the maximums of required values (water level, depth, velocity, hazard, ...) directly from TUFLOW simulation. FLT files are ESRI binary (float) version of the ASC files and their size is about 1/5 of an ASC file. Binary files can also be processed faster by TUFLOW utilities.<br>
