Line 141:
The user can choose to output the complete storm (preburst + design burst) rather than just the design burst by checking on the following option:<br>
[[File: ARR_complete_storm_checkbox.PNG | 300px]]<br>
The tool will use the preburst depth from the '''Preburst percentile''' option and the user will be required to select a preburst temporal pattern from the
* '''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.
* '''Temporal Pattern''' - This will apply the preburst depth using a temporal pattern obtained from the datahub for a given duration. The preburst duration can either be an absolute time or be proportional to the design storm. The user will need to select which temporal pattern to use (e.g. TP01, TP02,... TP10). Note: there is a minimum preburst duration of 10 min for this method.
