The ARR to TUFLOW utility has been developed to help users set up a TUFLOW model that uses Australian Rainfall and Runoff (ARR) input parameters and the Australian Bureau of Meteorology (BOM) rainfall by automating the collection and processing of the data. The inputs and outputs of the tool are explained in detail below. '''''Note:''''' this tool helps with data processing, however is not a substitute to reading ARR. Similarly this wiki page discusses the use of the tool and the options, however context should be derived from ARR directly. Please see the [https://arr.ga.gov.au/arr-guideline ARR Website] for more information.

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>
[[File: ARR_complete_storm_checkbox_01a.png]]<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
Currently the ARR to TUFLOW tool supports the following preburst temporal pattern methods:
* '''Constant Rate''' - This will apply the preburst depth equally over a given time period. The time period can be specified as an absolute time (either as minutes or hours) or proprotional to the design storm e.g. a proportional value of 0.5 will apply a 30 min preburst to a 1 hr storm and a 15 min preburst to a 30 min storm.
