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. As a consequence, the model result folders can get very large and the post processing of the results can be time intensive. The below page provides recommendations to minimise the effort and footprint of running TUFLOW for the latest ARR 2016 guidelines.
==Choice of Output==
As the model result folder can get large in size with the additional simulations, the preferred method of maximum grid output is to use FLT, which can be done directly from the 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>

. 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>
