Line 176:
* '''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.
** If "design burst" is selected, this will cause the pre-burst temporal pattern to use the same temporal pattern number as the design burst (e.g. TP01 design burst will use TP01 pre-burst, TP02 design burst will use TP02 pre-burst, etc.)
The initial loss value output in this method will be the raw storm initial loss value from the datahub with no post processing. Note, the complete storm option and using probability neutral losses are mutually exclusive and aren't able to be used together.<br>
