====Output Complete Storm====

The user can choose to output the complete storm (preburst + design burst) rather than just the design burst by checking on the following option (please see ARR Book 2 Chapter 5 [Section 5.9.9] for more information):<br>

The complete storm generated by the tool will be the preburst depth (from the '''Preburst percentile''' extracted from the datahub) plus the design burst. The user will be required to select a preburst temporal pattern from the options listed below. The options below have been included at the request of users and are not a direct reference to any specific methodology outline in ARR. If you would like to see another method included, please email <b><u>[mailto:support@tuflow.com support@tuflow.com]</u></b>.<br>

Currently the ARR to TUFLOW tool supports the following preburst temporal pattern methods:

Preburst temporal pattern and duration details are ignored if the "Use Complete Storm" checkbox is not selected.

====Why Is the Tool Outputting Negative Loss Values?====

The tool will output negative loss values when the preburst depth is greater than the storm initial loss. The tool will not floor loss values at zero since the value may be useful in helping the user determine the appropriate course of action. E.g. if IL = -1mm, this may be considered negligible and can be simply set to zero. An IL = -50mm may be considered significant enough that it simply can't be set to zero and alternate, or sensitivity runs, may need to be carried out, like using a <u><b>[[#Output_Complete_Storm | Complete Storm]]</b></u>.
